Answer 2

Messengers

Question 3

How are mRNA, tRNA, and rRNA the same and different?

Answer 3

Same: all RNA, made up of nucleotides and have Ribose (sugar)

Difference: have different functions

Question 4

Answer 4

UUU

Question 5

What is tRNA sequence to UUU?

Answer 5

(Anticodon) AAA

Question 6

tRNA molecule binds to what?

Answer 6

Specific Amino Acids

Question 7

What is tRNA’s function?

Answer 7

Translation

Question 8

rRNA are:

Answer 8

Essential building blocks of ribosomes

Question 9

How are DNA polymerase and RNA polymerase different?

Answer 9

No lagging strand, makes proteins, only replicates a chunk, it’s 1 stranded

Question 10

How are DNA polymerase and RNA polymerase the same?

Answer 10

Goes 5’——3’, and uses a Helicase, and use polymerase

Question 11

What are mRNA’s Enzyme regulations, in Eukaryotes?

Answer 11

GTP cap, and poly-A tail.

Question 12

What happens to Poly-A tail?

Answer 12

Gets eaten

Question 13

What happens to GTP cap?

Answer 13

Binds to ribosome

Question 14

Why does mRNA get spliced?

Answer 14

To create more protein products , and so there can be mutations for immune system

Question 15

Electrophoresis separates what and how?

Answer 15

Separates molecules according to size and charge.
