explain why it is important to keep the levels of nucleotides relatively balanced in the context of dna and rna synthesis
juin [17]

Answer:

Read Below

Explanation:

Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

A male bird has a genetic mutation that influences its mating behavior. This male bird performs a ritualistic dance that is very
mafiozo [28]

Answer:

This is a case of natural selection

Explanation:

Mutations are a fundamental part of the process of evolution by natural selection. These are a random genetic modifications that occur on every organism - some are beneficial and others could be harmful or disadvantageous. Therefore, natural selection decides which mutations will stay on a population and which ones will be eliminated.

In this scenario, this mutation enables the male bird to carry out better mating rituals, therefore it would be considered beneficial as it helps the species to reproduce and survive. So, it will be passed on from generation to generation, making other individuals fit for survival.

Explain how in glycolysis that the splitting of one glucose molecule results in 4 ATP but there is only a net gain of 2 ATP.
suter [353]
During glycolisys in cytoplasm, first step involves adding two phosphates to glucose molecule. This step requires the use of two ATP molecules. The next step is splitting 6 carbons glucose into two 3 carbons pyruvates. This step produces 4 ATPs and 2 NADHs. However, since we used up two ATPs during the initial phosphorylation, the net gain is only 2 ATPs
