2. What is RNA?
RNA, or ribonucleic acid, is a crucial molecule in biology.
It plays a vital role in protein synthesis and gene regulation.
Structure
RNA is a single-stranded molecule.
It uses ribose sugar.
Function
RNA carries genetic information. It
facilitates protein synthesis.
Types
Several types of RNA exist. Each has unique roles.
3. Types of RNA
1 mRNA
Messenger RNA carries
genetic code.
2 tRNA
Transfer RNA carries amino
acids.
3 rRNA
Ribosomal RNA forms
ribosomes.
4 Other RNAs
Many other functional RNAs
exist.
?Small nuclear RNA (snRNA)
?Regulatory RNAs.
?Transfer-messenger RNA
(tmRNA)
?Ribozymes (RNA enzymes)
?Double-stranded RNA (dsRNA)
4. The Central Dogma of Molecular
Biology
DNA Replication
DNA duplicates itself. Ensuring genetic continuity.
Transcription
DNA is transcribed. Creating messenger RNA.
Translation
mRNA is translated. Producing proteins.
5. RNA Synthesis (Transcription)
1 Initiation
RNA polymerase binds to DNA.
2 Elongation
RNA is synthesized.
3 Termination
Transcription ends.
6. RNA Processing and Modification
1. Capping
5' end modification.
2. Splicing
Intron removal.
3. Polyadenylation
3' end addition.
7. The Future of RNA
Technology
Gene Therapy
RNA-based therapies are
promising. Treating genetic
diseases.
Diagnostics
RNA detection is crucial. Early
disease diagnosis.
Research
RNA research continues to advance. Uncovering new functions.
