RNA

Question 1

Where is RNA located?

Answer 1

In the nucleus and in the cytoplasm

Question 2

What are the functions of RNA?

Answer 2

Deliver genetic information, make proteins

Question 3

What are the differences between RNA and DNA?

Answer 3

RNA has one strand. Contains ribose. Contains Uracil instead of Thymine.

Question 4

Transcription

Answer 4

the process that gets the sequence of nucleotides in DNA into a sequence of nucleotides in mRNA

Question 5

Translation

Answer 5

the process of the sequence of nucleotides in mRNA to the sequence of amino acids(proteins)

Question 6

Where does transcription occur?

Answer 6

Nucleus

Question 7

What nucleic acids are involved in transcription?

Answer 7

DNA and mRNA

Question 8

RNA polymerase

Answer 8

makes a new mRNA strand through base-pairing and linking RNA nucleotides together.

Question 9

What is the end result of transcription?

Answer 9

mRNA that leaves the nucleus

Question 10

Why does transcription occur?

Answer 10

Because DNA cannot leave the nucleus. mRNA is much smaller and can deliver the instructions to make proteins that happens outside the nucleus.

Question 11

RNA editing

Answer 11

Right after the mRNA is copied. Introns are removed, and exons are joined together to leave the nucleus.

Question 12

Exons

Answer 12

DNA sequences that codes for the making of proteins.

Question 13

Introns

Answer 13

DNA sequences that are not involved in the coding of proteins.

Question 14

Where does translation occur?

Answer 14

At/on the ribosome

Question 15

Ribosomes are made up of…

Answer 15

rRNA and proteins

Question 16

What nucleic acids are involved in translation?

Answer 16

mRNA, tRNA, rRNA

Question 17

mRNA in translation

Answer 17

contains the genetic code for the specific amino acids that should be used to make a protein

Question 18

tRNA

Answer 18

transports amino acids to the codon that complements the anti-codon of tRNA

Question 19

rRNA

Answer 19

ribosomal RNA that makes up the ribosome to mark every 3 nucleotides

Question 20

What is the anti-codon of GCA?

Answer 20

CGU

Question 21

How does translation work?

Answer 21

The ribosome reads and acts as a conveyor belt. For each codon, a tRNA with the complementary anti-codon brings the according amino acid.

Question 22

Why does translation occur?

Answer 22

To make proteins. Because the genetic code needs to be interpreted.

Question 23

If DNA’s template strand has ATCGATCG…what is the RNA strand?

Answer 23

UAGCUAGC

Question 24

How many possible codons are there?

Answer 24

64

Question 25

AUG codes for what?

Answer 25

Met or Start
