If the two oligonucleotides are allowed to anneal and the DNA polymerase and all substrates (4 dNTPs, etc.) are added to the mix, what will the first nucleotide incorporated in the DNA be?
a. A
b. C
c. G
d. T
e. U
Answer:
d. T
Explanation:
For a given DNA sequence, the array is represented as:
5'ATCCTGGACACTGTACCATCGGTACCAATCACAGGTCCTTACAGT 3'
And the premier; 5' GGACCTGTGA 3' attaches to the complementary base on the DNA sequence.
i.e.
5'ATCCTGGACACTGTACCATCGGTACCAATCACAGGTCCTTACAGT 3'
*AGTGTCCAGG
Thus, the first nucleotide that will be incorporated into the DNA will be T
What would happen in a cell if the DNA was destroyed completely or changed in any way?
Answer:
If the DNA of a cell is destroyed completely the cell would die i.e. cease to exist. A change in the DNA (germ-line mutation) would change the structure and/or functions of proteins in the cell.
Explanation:
The central dogma theory indicates that DNA is replicated to produce daughter cells. These daughter cells are then transcribed into mRNA (micro RNA) which are in turn translated into structural and functional proteins.
If the DNA is totally destroyed, no mRNA is formed and by implication, such a cell has no proteins. Now proteins are practically the "godfather" molecules in any cell, they maintain the selectively permeable cell membrane's integrity, they form the structural component of most cellular organelles, they are essential for transport of essential/toxic substances in/out of the cell, etc.
Looking at these functions, cessation of protein production is equivalent to cessation of cell life (apoptosis if DNA destruction is not stimulated externally).
A mutation (change in DNA) changes which protein is produced. A practical indication of this is when a single point mutation in hemoglobin produces sickle cell anemia!!
Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.
Explanation:
In simple terms, the term bipedalism refers to a term used to classify organisms that are equipped and use two legs or limp to walk, stand, jump or run.
One other nonprimate animal that is also a biped is the ostrich. When we compare the bipedalism of an ostrich with our (humans) bipedalism we discover that in terms of
Speed; an ostrich can move faster than an average human, reaching speeds of up to 70 km/h (43 mph).
limb length; its limb length can range from 10 to 16 feet (120 inches to 192 inches) which is far greater than the average length of an adult human's legs.
In the Hershey/Chase experiment phage proteins and DNA were radioactively labeled and allowed to inject coding material into bacteria. It was found that only radioactively labeled DNA was present in the bacterial cells which had been transformed. If radioactively labeled protein had been discovered in the transformed cells, what would this have told us about the molecules acting in genetics
A virus is made of two main components. A proteic capsid and genetic material. The Hershey/Chase experiment demonstrated that the virus introduces it's genetic material(DNA) inside the host cell to force it to make more viruses. This proved that genetic information is stored in DNA. If the marked proteins were found in the host cell that would have meant that proteins carry genetic information which they don't.

What causes uncontrolled cell division at the genetic level?
Answer:
mutations affecting proteins that normally regulate the cell cycle.
Explanation:
The function of the cell cycle is the duplication of DNA molecules in chromosomes and precisely separated by copying into two genetically identical daughter cells.
A tumor is an abnormal mass of tissue that results from the uncontrolled growth of cells.

Which statement best describes how organisms demonstrate the transformation of energy?
Light energy from the Sun is converted into mechanical energy in a rabbit, which is converted into thermal energy and dispersed into the atmosphere.
Light energy from the Sun is converted into chemical energy in a wildflower, which is converted into mechanical energy in a deer that eats the wildflower.
Light energy from the Sun is converted into mechanical energy in a deer, which produces waste that is absorbed by a wildflower to produce chemical energy.
Light energy from the Sun is converted into chemical energy in a mushroom, which is converted into thermal energy as the mushroom breaks down dead matter.

Explain the all-or-none law of action potentials and describe the effect of increased stimulus strength on action potential production. How do the refractory periods affect the frequency of action potential production
If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.

Which two things are found on a molecule of tRNA
Answer: Ribose nucleotides and the nitrogenous bases
Explanation: RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.
Answer:RNs and nitrogenous bases
Explanation:
Ribose nucleotides and the nitrogenous bases

What change is most likely
responsible for the trout decline? *
Answer:
Rise in temperature.
Explanation:
Increase in temperature is responsible for the decline in the population of trout because trout needs low temperature for better growth and survival. Due to more consumption of fossil fuels in vehicles and industries, more carbondioxide gas is released which causes air pollution. This air pollution increases the temperature of the earth surface known as global warming due to which the cold areas become warm and as a result the trout population decreases.

Which of the following do sage grouse and California tiger salamanders have in common?
They both thrive on ranchlands used for grazing.
They both consume vegetation that cattle cannot eat.
They both play a critical role in balancing the ecosystem of ranchlands.
They both establish mutualistic relationships with grazing herd animals.
Answer:
The answer is "They both play a critical role in balancing the ecosystem of ranchlands"
Explanation:
The more prominent sage-grouse, otherwise called the sagehen, is the biggest grouse (a kind of bird) in North America. Its reach is sagebrush nation in the western US and southern Alberta and Saskatchewan, Canada. It was known as essentially the savvy grouse until the Gunnison sage-grouse was perceived as a different animal groups in 2000. The Mono Basin populace of sage grouse may likewise be unmistakable.
The more noteworthy sage-grouse is a lasting occupant in its favorable places however may move short distances to bring down heights during winter.
Answer:
They both thrive on ranchlands used for grazing.

Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
an increase in food availability
an increase in pollution
a decrease in tuna fishing
a decrease in tuna predators
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
Other options, such as an increase in food availability, a decrease in tuna fishing or a decrease in tuna predators, are environmental factors that contribute to increased genetic variability.Answer:
B

important tasks a cell must complete to divide
Answer:
Cells must divide to perform functions such as growth of the organism, replacement of damaged or old cells, and asexual reproduction in some organisms.
Explanation:
Answer:
To divide, a cell must complete several important tasks: it must grow, copy its genetic material (DNA), and physically split into two daughter cells.
Explanation:
Cells perform these tasks in an organized, predictable series of steps that make up the cell cycle.
