1. BTY100-Lec#4.2
DNA to Protein (Central Dogma)

2. Outline Gene Central Dogma: DNA to Protein Replication Transcription
Translation

3. GENE A Gene is a segment of DNA and is located on the chromosome.
Gene specifies the structure of particular protein that make up each cell.

4. Structure of Gene Composed of Exons Introns(absent in prokaryotes)
Control elements

5. Intron – Non coding sequence Only present in Eukaryotes!!
EIKB
Non Coding Regions

Exons
Exon – Coding sequence
Intron – Non coding sequence
Only present in Eukaryotes!!

6. Central Dogma: DNA to Protein

7. DNA Replication
Process of producing two identical replicas from one original DNA molecule. It occurs with the help of a lot of enzymes/catalyst.

8. Transcription: Process of Formation of RNA from DNA

9. TRANSLATION: Process by which 3 bases Form 1 Codon
RNA (mRNA) produced by transcription is decoded by a ribosome complex to produce a protein
3 bases
Form 1 Codon
Codon codes for amino acids
Many amino acids joint together to form a protein
Example???.
