4.2 DNA replication and protein synthesis Flashcards
1
Q
ribonucleotides anneal to the ? strand
A
template
2
Q
What catalyses the condensation of phosphodiester bonds between adjacent ribonucleotides?
A
RNA polymerase
3
Q
What happens when the pre-mRNA strand has formed? (transcription)
A
single stranded RNA molecule detaches
4
Q
What is the strand that has undergone splicing called?
A
mature mRNA
5
Q
process of translation (3 steps)
A
- ribosome forms around mRNA
- tRNAs line up, carrying amino acids
- inside the ribosome, ribosome breaks bonds between tRNA and amino acid and catalyses the condensation of peptide bonds between amino acids
