Sagot :

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
