2. All of the following are differences between RNA and DNA except
ORNA has uracil instead of thymine.
O RNA is single stranded and DNA is double stranded.
ORNA has ribose sugar instead of deoxyribose.
ORNA is found only in prokaryotic cells, while DNA is found in both.

Option D. RNA is found only in prokaryotic cells, while DNA is found in both, is the correct option.

Explanation:

RNA is found in all cells i. e. Prokaryotic and eukaryotic cells. RNA is a molecule which is responsible for the production of protein for the cell. The main difference between DNA and RNA structure is uracil in place of thymine and ribose sugar in place of deoxiribose.

RNA is found only in prokaryotic cells, while DNA is found in both.

Explanation: RNA is found in all cells both prokaryotic and eukaryotic cells. RNA is a single stranded nucleic acid that contains the information for the production of proteins. There are three classes of RNA: messenger RNA, transfer RNA and ribosomal RNA, and they are all found in every living cell whether prokaryotic or eukaryotic cells.

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

i don't know. if i were you, i would search it up online : d
