Begins with mRNA
Binds to anti codon
Contains tRNA
contains amino acids
make protein
Can fit two ribosomes
Contains codons
starts with DNA
unzipped by RNA polymerase
Creates mRNA
Primase
Starting point for DNA synthesis
Synthesizes short RNA primers
SSB
Keeps DNA strands separated
DNA polymerase
adds nucleotides
in 5'->3' direction
Topoisomerase
Prevents DNA from recoiling
DNA helicase
Replication fork is formed
lagging strand
discontinuously synthesised
