Question

both dna and rna consist of a phospno - sugar backbone
both dna and rna have a double helix structure
both dna and rna carry genetic information
rna is single stranded
where does dna replication occur? *
in the nucleus of a cell
in the chloroplast of a cell
in the cell membrane of a cell
in the cytoplasm of a cell

Explanation:

• First question:
• DNA and RNA both have a phospho - sugar backbone. DNA has a double - helix structure, while RNA is usually single - stranded. Both can carry genetic information (DNA is the main store, but some viruses use RNA).
• Second question:
• DNA replication occurs in the nucleus of a eukaryotic cell. Chloroplasts have their own DNA but are not the main site for general DNA replication of the cell. The cell membrane is not involved in DNA replication, and the cytoplasm (except for organelles like mitochondria which have their own limited DNA replication) is not the site for nuclear DNA replication.

Answer:

• First question: Both DNA and RNA consist of a phospho - sugar backbone; Both DNA and RNA carry genetic information; RNA is single stranded.
• Second question: in the nucleus of a cell.
