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 Introns Parts of Gene BIKE 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???.
