Answer:
B) missense mutation
Explanation:
A type of base substitution that results in the replacement of one amino acid by another is called missense mutation. Missense mutations affect the mutated proteins in several ways. It may alter the amino acid composition of the active site of enzymes and render the enzymes inactive.
The wild type polypeptide chain has the following sequence of amino acids: Met-Ala-Gln-Arg-Glu-Leu. The mutated polypeptide has glycine in place of arginine. The rest of the amino acids are the same in wild type and mutated protein. This means that the mutation changed the genetic code of arginine into the genetic code of glycine resulting in the incorporation of glycine in position 4. This is an example of a missense mutation.
I believe it is C, but i cant be sure
I hope i helped a little :)
Point mutations are the substitution of a single nucleotide, which creates a different codon and therefore a different amino acid. the incorporation of a different amino acid in the protein can completely disrupt the normal function of proteins.
Explanation:
Conjunctivitis is the inflammation of the transparent mucous membrane, that covers the white part of the eye.
- Bacterial conjunctivitis can be cure with the help of antibiotics, but viral cannot.
- The discharge from eye is clearer and less thick in viral conjunctivitis as compared to bacterial.
- Viral conjunctivitis is self-limited, while bacterial is not.
- Viral can cause painful swelling in lymph node nearest the ear, which is not there in bacterial conjunctivitis.
