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