Question

a) 1:3
b) 3:1
c) 1:2
d) 2:1

Answer 1

Answer:

answer b correct 100 percent warrinty

Answer 2

The ratio of capsomere nucleotide in TMV is a) 1:3.

Explanation:

• Tobacco mosaic virus (TMV) is a positive sense single stranded RNA virus that infects a wide range of plants especially tobacco and other members of the family solanaceae.
• TMV is a simple rod shaped helical virus consisting of single stranded RNA enveloped by a protein coat called capsid.
• There are 49 capsomeres on every three turns of the helix.
• The protein sub unit that assembles into a capsid protecting the genetic material of the virus.
• A nucleotide is the basic building block of nucleic acids.
• RNA and DNA are polymers made of long chains of nucleotides.
• A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen containing base.
