Question

1. complete the following chart.

compare by	dna	rna
type of sugar
# of strands
types

Explanation:

DNA uses thymine and deoxyribose, is double-stranded, and has types like nuclear DNA. RNA uses uracil and ribose, is single-stranded, and includes mRNA, tRNA, rRNA. These are core structural and functional differences between the two nucleic acids.

Answer:

Compare by	DNA	RNA
Type of sugar	Deoxyribose	Ribose
# of strands	Double-stranded	Single-stranded
Types	Nuclear DNA, Mitochondrial DNA, Chloroplast DNA	mRNA, tRNA, rRNA
