Question 11

TERMINATION?

Answer 11

WHERE IT STOPS, DONE BY POLY A, IN EUKARYOTES TRANSCRIPTION OCCURS 10 TO 35 UNITS PAST THIS THING

Question 12

ANTICODON?

Answer 13

BASE PAIRS W COMPLEMENTARY CODON ON MRNA

Question 14

3 BINDING SITES IN RIBOSOME?

Answer 14

1. A SITE= HOLDS TRNA THAT CARRIES NEXT AA TO BE ADDED
2. P SITE= HOLDS TRNA THAT CARRIES THE CREATED POLYPEPTIDE
3. E SITE= WHERE THEY EXIT
