Transcription/translation

Question 1

What is the first step of transcription?

Answer 1

The enzyme RNA polymerase breaks hydrogen bonds between bases

Question 2

What is the second step of transcription?

Answer 2

RNA nucleotides, that come from food, will bond to their complimentary bases on DNA strands

Question 3

What is the third step of transcription?

Answer 3

RNA polymerase will bond sugars to phosphates

Question 4

Involving with RNA, what two bases bond together?

Answer 4

G and C

A and U

Question 5

What is replaced with what compared to DNA from RNA?

Answer 5

T is replaced with U

Question 6

The assembling of amino acids to make a protein is what?

Answer 6

Translation

Question 7

mRNA can also be known as

Answer 7

Templet

Question 8

mRNA is made through ______________

Answer 8

Transcription

Question 9

The 1st codon is ALWAYS …

Answer 9

AUG

Question 10

AUG can be known as

Answer 10

The universal start codon

The universal initiator codon

Question 11

What is the 1st step of translation?

Answer 11

mRNA is made through transcription

Question 12

What is the 2nd step of translation?

Answer 12

mRNA will leave the nucleus and will attach to a ribosome

Question 13

What is the 3rd step of translation?

Answer 13

In the cytoplasm, there are amino acids (food)

Question 14

What happens in the 4th step of translation?

Answer 14

tRNA will be made through transcription the tRNA is going to leave the nucleus and it’s free codon is going to bond to its complimentary codon on an amino acid

Question 15

What is the 5th step of translation?

Answer 15

The anticodon on the tRNA will bond to its complimentary codon on mRNA on the ribosome

Question 16

What is the 6th step of translation?

Answer 16

tRNA will drop off the amino acid and will COULD pickup another amino acid but USUALLY dissolves

Question 17

What is the 7th step of translation?

Answer 17

Either the mRNA moves along the ribosome or vica versa

Question 18

What is the 8th step of translation?

Answer 18

An enzyme will bond amino acids into a protein

Question 19

DNA passing its code to RNA

Answer 19

Transcription

Question 20

What is the outside of DNA made up of?

Answer 20

Phosphates

Question 21

Why must replication take place?

Answer 21

Because we lose many cells

Question 22

U dealing with RNA stands for

Answer 22

Uracil

Question 23

Question 24

mRNA is a ______ strand

Answer 24

Uncoiled

Question 25

Answer 26

54

Question 27

How many different amino acids are there?

Answer 27

20

Question 28

What are the 3 codons that aren’t associated called?

Answer 28

Nonsense codons

Question 29

What is ALWAYS the first 3 codons?

Answer 29

AUG

Question 30

AUG is known as the

Answer 30

Universal initiator codon

Question 31

tRNA picks up and delivers what???

Also, at the top of the tRNA what bonds with what?

Answer 31

Amino acids

Top of tRNA the codon bonds with amino acids

Question 32

4 examples of proteins

Answer 32

Hair, skin, nails, muscles

Question 33

Once tRNA picks up an amino acid.. How does it know where to go?

Answer 33

Because anti codons bond to their complimentary codons on mRNA ON THE RIBOSOME
