Question

lysine is important in functioning of particular enzyme. A mutation resulted due to which lysine is replaced with either glycine, glutamate,valine or arginine. which mutation would be least harmful and which mutation
would be most harmful for the enzyme?
A. glycine arginine
B. valine glutamate
c.arginine glutamate
d. arginine glycine



​

Answer 1

arginine glutamate

Explanation:

i hope it helps you

Answer 2

Answer:

Most: Glutamate

Least: Arginine

Explanation:

• The persistent positive charge of lysine frequently bonds to DNA's negative phosphate backbone. The positive charge of arginine makes it possible for similar interactions to occur. The negative or hydrophobic amino acids glutamate or valine would prevent binding.
• A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations. Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
• A missense mutation is a DNA alteration that causes the protein produced to encode a different amino acid at a specific location. Some missense mutations change how the resulting protein functions.
