transcription & translation Flashcards
1
Q
what is the start codon?
A
AUG
2
Q
what are the 3 option for a stop codon
A
UAA, UAG or UGA
3
Q
the ribosomes reads how many nucleotides at a time
A
3 (starts with AUG)
4
Q
when does transcription switch to being translation
A
as soon as the mRNA leaves the nucleus
5
Q
what does each triplet being read determine
A
which amino acid is added to the protein chain
6
Q
what brings the amino acids to the ribosome
A
tRNA
7
Q
up to how long can the protein chain grow
A
up to 600 amino acids long
8
Q
what happens when the complete chain is detached from the ribosome
A
it folds itself into a protein and leaves the cell to play its role in the body
9
Q
what are the 3 differences between mRNA and DNA
A
DNA: double stranded, sugar= deoxyribose, thymine
mRNA: single stranded, sugar= ribose, uracile
