A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation. It can be a deletion, addition or inversion of a single nucleotide base.
In the following, the mutations that occurred are 1. C and 2. B.
<h3>How the mutation can be explained?</h3>
- <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.
- <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.
Therefore, silent and nonsense mutations are the correct options.

Also may decline with age in older adults as a result of the yellowing of the lens of the eye. Decline is most likely to occur in the green blue violet part of the color spectrum. Result is trouble accurately matching closely related colors.
Answer:
The tail of an ATP molecule is made up by 3 phosphate groups link together by the help of 2 high energy phospho anhydride bonds.
Explanation:
ATP or adenosine tri phosphate is an energy rich compound that contain adenine base, ribose sugar and 3 phosphate groups.
These 3 phosphate groups makes up the tail of ATP molecule.The 3 phosphate groups are designated as alpha phosphate,beta phosphate and gamma phosphate starting from the C5 atom of ribose sugar.
When ATP undergo hydrolysis the terminal phosphate group or the gamma phosphate group is cleaved from the ATP molecule resulting in the formation of ADP and inorganic phosphate along with the generation of high amount of free energy that is utilized by the cell to perform various cellular and physiological activities.

Explanation:
The sequence of DNA is transcribed into mRNA, containing the sequence for protein synthesis, protein is synthesized according to the codons in mRNA. This sequence of nucleotide on DNA/ RNA is divided into a series of three nucleotide units, and one unit of three nucleotide is known as codons.
There are overall 64 codons, 61 codons out of 64 codons, codes for overall 20 amino acids, and the remaining three are stop codons.
These there codon do not code for any amino acid.
And these 61 codons, they code for total 20 amino acids. So one amino acid can be coded by one or more than one codons.
