Ch10: From DNA to Protein: Gene Expression Flashcards
Brings together mRNA, Ribosome subunits, and the initiator tRNA
Initiation
Adding amino acids based on the codon sequence
Elongation
The End Codon
Termination, UAA
3 phases of building a polypeptide
Initiation, Elongation, and Termination
“The junk.” Intervening regions
Introns
The “real gene;” Expressed regions/coding DNA
Exons
This guy is…
Not awesome
Transcribed DNA strand
Template strand
Untranscribed DNA strand
Coding Strand
The Formation of a specific RNA sequence from a specific DNA sequence
Transcription
This edits out introns in order to splice exons together. This makes a mature mRNA transcript. Also referred to as “Post-transcriptional processing.”
mRNA splicing
These facilitate the coupling of tRNA anticodon to mRNA codon
Ribosomes
The “Cook Book”
DNA
“The Recipe”
mRNA
“The Chef”
The Ribosomes
DNA-RNA-Proteins-Phenotype(you) Discovered by Watson and Crick.
Central Dogma
Creates mRNA through transcription (initiation, elongation, termination)
RNA Polymerase
The mRNA is scythed through a ribosomes and amino acids a are formed. They are formed into a polypeptide chain.
Translation
How many “letters” on the codon code per amino acid?
3
The type of RNA that is responsible for carrying the “code” from DNA to the ribosomes
Messenger RNA (mRNA)
The type of RNA a ribosomes are composed of:
tRNA
The Type of RNA that is responsible for bringing the correct amino acid to the Translation site:
tRNA
G
Codons
“Start codon”
AUG
