hydrogen binds

Question 26

iwhat is the start code

Answer 26

methionine

Question 27

what is a promotor

Answer 27

control the binding of RNA polymerase to DNA

Question 28

what happens in imitation

Answer 28

ribosomes formed-mRNA feeds through the ribosomes and methionine start’s process

Question 29

what happens in enlongation

Answer 29

tRNA delivers amino acids and chain is growing

Question 30

what happens in termination

Answer 30

stop code terminates the growth- mRNA breakdowns and ribosome disintegrates
