Structures and functions that DNA have in living beigs
Structure
1-4 standed structures
Found in chromosomes
The two strands wrap around each other to form a helix
The strands are held together by base pairing and are antiparallel
B-form
Very common
The ribose-phosphate backbones run along the outside of the helix
The basepairs are roughly perpendicular to the axis of the helix.
A-form
Right handed double helix tha has 11 base pairs per turn
Has a wider diameter than B-form
Z-form
Narrow
Irregular left-handed double helix
Replication
Helicase
Primase
Primer
DNA polymerase
Okazaki fragments
Leading strand
Lagging strand
Ligase
Transcription
RNA polymerase
Promoter
Template strand
Coding strand
Transcription factors
mRNA (messenger RNA)
Initiation
Elongation
Termination
