Study Notes
Importance of DNA and RNA
- DNA stores the genetic instructions for all living organisms.
- RNA plays a crucial role in protein synthesis and gene regulation.
Structural Differences Between DNA and RNA
- DNA: A double-stranded helix. Its sugar is deoxyribose. The base thymine is found in DNA.
- RNA: A single-stranded molecule. Its sugar is ribose. The base uracil is found in RNA instead of thymine.
Functional Differences Between DNA and RNA
- DNA: Primarily responsible for storing and transmitting genetic information to the next generation.
- RNA: Has diverse functions. It's involved in protein synthesis (mRNA). Other types of RNA (tRNA and rRNA) also assist in translation. It also plays a role in gene regulation.
