Answer:

Removing a phosphate group from an ATP molecule

Explanation:

ATP or Adenosine Triphosphate molecule is called energy currency of the cell because organisms store energy in them. It is used for energy storage for reactions inside body and used whenever energy is required. It is made of adenine base which is attached to a ribose sugar. The sugar moiety is further attached to three phosphate groups.

The three phosphate groups are bonded to each other by two phosphoanhydride bonds which are high energy bonds. When the first phosphoanhydride bond is broken by hydrolysis, a phosphate group is removed from ATP and it is converted into ADP releasing a lot of energy. Second phosphoanhydride bond can also be broken to convert ADP to AMP again releasing energy.

Original Codon: CTC GAG

Vesna [10]

The original codons code for Leucine and Glutamic acid. The mutated codons code for Valine and Glutamine.

<h3>Genetic codes and amino acids</h3>

Each of the genetic codes. otherwise known as codons, translates to an amino acid.

Following the table of genetic codes with their respective amino acids:

CTC (CUC) codes for Leucine
GAG codes for Glutamic acid
GTC (GUC)codes for Valine
CAG codes for Glutamine

Thus, the glutamic acid in the original codon has been replaced with glutamine in the mutated codon while Leucine has been replaced with Valine.

Is natural selection the only means of evolution? Explain.

Sunny_sXe [5.5K]

Answer:

Much change is due to random genetic drift rather than positive selection. Some are harmful and are likely to be eliminated by natural selection – by death of the embryo, for instance. ...
