Q

what is the process of removing introns from the mRNA

A

intron splicing

18
Q

what performs intron splicing; complex made up of proteins and RNA

A

spliceosome

19
Q

where does the mRNA enter to begin translation

A

cytoplasm

20

Start codon

A

AUG

22
Q

Stop codon

A

UAA
UAG
UGA

23
Q

when does translation begin

A

when the mRNA binds to the small ribosomal subunit at the start codon

24
Q

what molecule brings the amino acid

A

tRNA

25
Q

what does the tRNA bring

A

anticodon

26
Q

when will the large ribosomal subunit binds to form the translation complex

A

when the initiator tRNA binds to start codon

27
Q

three distinct regions of the large ribosomal subunit

A

EPA sites

28
