DNA & RNA

Question 1

What happens after translation?

Answer 1

Code is in RNA language

Question 2

What does each codon code for?

Answer 2

Amino acids or STOP

Question 3

How many different amino acids are there?

Answer 3

20-64 possibilities

Question 4

How does translation begin?

Answer 4

With MRNA attaching to the ribosome

Question 5

What brings in the correct amino acid to the ribosome?

Answer 5

TRNA

Question 6

Translation continues until when?

Answer 6

The STOP codon is reached

Question 7

What pops off the ribosome and goes where it’s directed in the cell?

Answer 7

protein

Question 8

How is the code for MRNA read?

Answer 8

3 letters at a time

Question 9

After Translation what code is it in?

Answer 9

RNA language

Question 10

RNA is made of….

Answer 10

subunits of nucleotides

Question 11

What are nucleotides made of?

Answer 11

Sugar/ribose, single phosphate, RNA single stranded, Uracil replaces thymine

Question 12

What are three types of RNA?

Answer 12

MRNA, TRNA, rRNA

Question 13

What does MRNA do?

Answer 13

messenger…carries a copy of instructions on how to build a protein

Question 14

What does TRNA do?

Answer 14

transfer…brings amino acids to the ribosome to build the protein

Question 15

What does rRNA do?

Answer 15

Ribosomal…actual code on the ribosome where a specific protein is made

Question 16

What is transcription?

Answer 16

Moving RNA from DNA

Question 17

What does RNA polyamerase do

Answer 17

unzip the DNA & brings in new nucleotides

Question 18

What does promoter sequence on DNA do?

Answer 18

says where to begin

Question 19

What does one strand of DNA do?

Answer 19

Acts as the template

Question 20

How many strands of of RNA come from a strand of DNA

Answer 20

1

Question 21

When RNA is edited where does it go?

Answer 21

It leaves the nucleus

Question 22

Where does the final edited RNA go?

Answer 22

Leaves the nucleus and goes to cytoplasms(ribosome)
