1.2. Anatomy Of A Gene Flashcards
1
Q
Gene
A
Segment of DNA that is expressed to yield a functional product, either a RNA or a protein
-> the complete sequence region necessary for generating a functional product
2
Q
Sense strand
A
5’ to 3’
- DNA sequence is written as the base sequence of a sense strand
3
Q
Antisense strand
A
3’ to 5’
- template strand to which polymerase bonds
4
Q
Enhancer
A
Activated the utilization of a promoter, controlling the efficiency and rate of transcription
5
Q
Promoter
A
Controls gene activity
- bonding of RNA polymerase & initiation of transcription
6
Q
Exon
A
Protein coding region of DNA
7
Q
Intron
A
Non protein coding region of DNA
8
Q
Splicing
A
Removal of intron sequences from pre-mRNA & splicing together of exon sequences
