Gene transcription Flashcards
1
Q
Leading strand (DNA replication)
A
Synthesis from leading strand occurs continuously from RNA primer
2
Q
Lagging strand (DNA replication)
A
Synthesis from lagging strand is discontinous via backstitching of
Okazaki fragments
3
Q
Gene transcription
A
DNA -> RNA -> protein
4
Q
Transcription
A
DNA to RNA
5
Q
Translation
A
RNA to proteins
6
Q
Transcription regulation
A
A DNA transcription unit coding for a protein contains the sequence that will be translated into the protein, along with regulatory sequences
