Protein Synthesis

Question 1

Transcription

Answer 1

mRNA using DNA as a template

Question 2

Helicase

Answer 2

uncoils double helix of DNA

Question 3

mRNA is formed

Answer 3

When RNA nucleotides (RNA polymerase) form base pairs with the exposed DNA

Question 4

After mRNA is formed

Answer 4

The message from the DNA is transcribed onto the the RNA

Question 5

Using restriction enzymes

Answer 5

the non coding regions are removed from the copied mRNA

Question 6

Finally mRNA does what?

Answer 6

Detaches from the strand and moves out into the cytoplasm

Question 7

Translation

Answer 7

Protein production at a ribosome

Question 8

Cytoplasm contains what?

Answer 8

tRNA molecules, each carrying a single amino acid

Question 9

Determined by the codons on mRNA

Answer 9

the tRNA carrying a complementary code(anticodon) bonds to a mRNA

Question 10

In the ribosome

Answer 10

The codons are processed (two at a time), the amino acids are separated from the tRNA and join up to form a protein

Question 11

Histones do what

Answer 11

Make the protein shape

Question 12

Washing up liquid

Answer 12

Disrupts the membrane

Question 13

Sodium chloride (salt)

Answer 13

Clumps the DNA

Question 14

Protease

Answer 14

Breaks down the protein in the chromosome

Question 15

Freezer-cold ethanol

Answer 15

Separate the DNA

Question 16

RNA polymerase

Answer 16

Synthesises mRNA
