Question

1. How are the structures of DNA in prokaryotes and eukaryotes the same?
The DNA is packaged into several linear chromosomes.
They both have a singular circular chromosome.
They both have a sugar and a phosphate group backbone.
The DNA histones are present in the nucleosomes.

2. How are the structures of DNA in prokaryotes and eukaryotes different?
Prokaryotes have DNA in circular chromosomes, and eukaryotes have linear chromosomes.
Prokaryotes have DNA in linear chromosomes, and eukaryotes have circular chromosomes.
DNA in prokaryotes is circular and lacks sugar and phosphate backbones.
DNA in eukaryotes is circular and lacks sugar and phosphate backbones.

Answer 1

Answer:

1. Option C, They both have a sugar and a phosphate group backbone

2. Option A, Prokaryotes have DNA in circular chromosomes, and eukaryotes have linear chromosomes.

Explanation:

1. Both the circular and linear DNAs in prokaryotes and eukaryotes respectively are made up of sugar-phosphate backbone. However, the arrangement is different due to which they have different shapes. Thus, option C is correct

2. Eukaryotes have multiple linear DNAs while prokaryotes have circular DNA having simplified structure.

Thus, option A is correct
