|
Which do DNA and RNA have in common?
|
|
Both are double stranded.
|
|
|
Both contain ribose molecules.
|
|
|
Both contain phosphate groups.
|
|
|
Both contain uracil.
|
Explanation:
Detailed explanation-1: -One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach. Because of the phosphate group, this backbone is negatively charged-a quality many genetic techniques appreciate and exploit.
Detailed explanation-2: -An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G).
