Transcription-first stage of protein synthesis Flashcards
1
Q
Stage 1
A
RNA polymerase attaches to the DNA double helix
2
Q
Stage 2
A
Hydrogen bonds between the two DNA strands break, separating the strands
3
Q
Stage 3
A
One strand is used as a template to make mRNA copy
4
Q
Stage 4
A
Complimentary free RNA nucleotides pair with a complimentary basis of the DNA
5
Q
Stage 5
A
RNA nucleotides once parked up join together forming a mRNA molecule
6
Q
Stage 6
A
RNA polymerase moves along DNA strand while assembling the mRNA strand
7
Q
Stage 7
A
Hydrogen bonds between the uncoiled strands on DNA re-form once the RNA polymerase has passed by and could back into a double helix
8
Q
Stage 8
A
Ems polymerase reached a stop codon and detached from DNA
9
Q
Stage 9
A
mRNA moves out of the nucleus via the nuclear pore and attaches to a ribosome
