Difference between DNA and RNA

Characteristic

DNA

RNA

Structure

Double-stranded helix

Single-stranded

Bases

Adenine (A), Thymine (T), Cytosine (C), Guanine (G)

Adenine(A), Uracil (U), Cytosine (C), Guanine (G)

Sugar

Deoxyribose

Ribose

Location in Cells

Mostly in the cell nucleus

Found in both nucleus and cytoplasm

Function

Genetic information storage and transmission

Gene expression, protein synthesis, and various cellular processes

Replication

Yes, during cell division

No regular replication; synthesized as needed

Stability

More stable

Generally less stable

Types

Nuclear DNA, Mitochondrial DNA

mRNA, tRNA, rRNA

Role in Protein Synthesis

 Template for mRNA during transcription

Translated into proteins during translation

Genetic Code

Provides genetic code for protein synthesis

Carries genetic instructions from DNA to ribosomes

Mutations

Can lead to genetic variations and mutations

Mutations contribute to genetic diversity

Lifespan

 Longer lifespan

Some RNA molecules have short lifespans
