Which of these sequences signals
mRNA to start translation?
A. UAG
B. GUA
C. AUG
D. AGU
Answer:
AUG
Explanation:
The sequences signals mRNA to start translation is AUG. The correct option is C.
The start codon and signal for the beginning of mRNA translation is the sequence AUG. It is recognised by the ribosome as the starting point for protein synthesis and codes for the amino acid methionine.
The ribosome binding site, which comes before the initiation codon AUG, is normally located close to the 5' end of an mRNA molecule.
The ribosome recognises the AUG start codon during translation, assembles the essential parts, and starts constructing the polypeptide chain.
The other choices (UAG, GUA, and AGU) are stop codons, which mark the end of translation as opposed to its beginning.
Thus, the correct option is C.

What is the overall net gain of ATP in aerobic respiration per one molecule of glucose? between 0-10 between 10-20 between 30-40 between 40-50.
Answer:
C on edge
Explanation:
C. 30-40 i took the test on edge for biology so trust me, I got 100% :D have a good day
The overall net gain of ATP in aerobic respiration per one molecule of glucose is 38 ATP, that means between 30-40.
What is meant by aerobic respiration ?Aerobic respiration is defined as the process of respiration in which glucose is broken down by using oxygen in order to make energy from carbohydrates.
Here,
Aerobic respiration is the cellular respiration which includes some chemical processes for the production of energy from glucose in the presence of oxygen.
In respiration, the energy is released in the form of ATP or adenosine triphosphate.
Aerobic respiration consists of various steps like, Glycolysis, Krebs cycle and the electron transport system. The energy generated during all of these processes is called the net ATP.
During the process of glycolysis, a total of 8 ATP is produced.
During Krebs cycle and electron transport chain, a total of 30 ATP is produced.
So, the overall net ATP produced is 38.
Hence,
The overall net gain of ATP in aerobic respiration per one molecule of glucose is 38 ATP, that means between 30-40.

During independent assortment, what are separated from one another?
Answer:
The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop.... During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.
During independent assortment, alleles of different genes located on different chromosomes are separated from one another.
Independent assortment is a fundamental principle in genetics that describes how alleles of different genes segregate into gametes independently of each other. This phenomenon occurs during meiosis, the process by which cells divide to produce gametes (sperm and egg cells).
In meiosis, homologous chromosomes (chromosome pairs) separate during the first division (meiosis I), ensuring that each gamete receives one chromosome from each pair. Additionally, independent assortment occurs during meiosis I as well as meiosis II.
During independent assortment, alleles located on different chromosomes are sorted into gametes without regard to the alleles of other genes. This means that the inheritance of one gene does not influence the inheritance of another gene located on a different chromosome. As a result, different combinations of alleles from different genes can end up in gametes, leading to genetic diversity in the offspring. This genetic variation is a crucial factor in evolution and the adaptation of populations to changing environments.
Overall, independent assortment contributes to the shuffling of genetic material and the creation of unique genetic combinations in sexually reproducing organisms, enhancing genetic diversity within a species.
