Mademuasel [1]

Answer:

(D) The protein that is first made gets modified afterwards

Explanation:

The first amino acid in any protein in eukaryotes is always methionine (Met). But, in some proteins any amino acid other than methionine may be found at N terminus of a protein. Like in this example, the HBB protein starts with a valine (Val) instead of methionine. It happened because of post-translational modification which includes the action of aminopeptidases which cleave 1 or 2 amino acids from N terminus of a protein as a result of which any  amino acid other than methionine may exist at amino terminus.

What structure will form during synapsis in Prophase I if there is a partial chromosome deletion or duplication?
Mariana [72]

Answer:

The correct answer is option e, that is, unpaired loop.

Explanation:

For base pairing to take place, the duplicated or the deleted region will not possess any kind of complementary region. Thus, it produces an unpaired loop. The formation of the inversion loop takes place at the time of paracentric and pericentric inversion. A high-level packaging composition produced by chromatin is known as a solenoid. A bead on string structure produced by enveloping DNA around the core of histone proteins is termed a nucleosome.
