Question

please tell me which one I got worng

Depurination involves the removal of a purine (G or A) from the DNA there's a 75% chance of a mutation Covalent bond between deoxyribose and a purine base is somewhat unstable a and b a and all of the above are correct Huntington's Disease caused by TNRE As # of (CAG) repeats increases (above 36), the rate of deterioration of mental and physical abilities increases is a genetic phenomenon called anticipation all of the above are correct

Answer 1

1. Answer: Option E is correct
Explanation:
Durination involves removal of a purine (A or G) from the DNA.
The bond connecting the purine and the C1 of sugar is intrinsically unstable.

2. Answer: Option D is correct
Explanation:
Huntington disorder is triplerepeat expansion disorder (Expansion of CAG repeats)
It exhibits genetic anticipation.

Translation occurs in the cytoplasm in both prokaryotes and eukaryotes.

An organism's genetic information is stored in the sequence of DNA. This information is transcribed into a sequence of RNA, which are then translated into a sequence of amino acids (Protein/polypeptide)

Answer: Option B is correct
Explanation:
Enhancer = Activator binding site
Silencer = repressor binding site
