Cytosine (C) - Adenine (A)

Adenine (A) - Guanine (U)

Thymine (T) - Cytosine (C)

Cytosine (C) - Guanine (G)

Question 2

2.

In order to make a protein, the DNA of a gene first has to be transcribed into

DNA

protein

amino acid

RNA

Question 3

3.

Match the type of RNA on the left with the correct function on the right.

mRNA
rRNA
tRNA

carries instructions for protein synthesis from the nucleus to the cytoplasm
carries amino acids to the ribosome and mtches them to the coded mRNA message
forms an important part of the ribosome

made up of nucleotides
type of nucleic acid
moves into the cytoplasm
found only in the nucleus

BOTH DNA & RNA

Question 6

6.

Match the enzyme on the left with the correct step of DNA replication on the right

DNA polymerase
DNA helicase

"unzips" the DNA molecule into two separate strands
adds free nucleotides to the original strands of nucleotides using base-pairing rules.
