Question 9

Codon

Answer 9

A sequence of 3 bases

Question 10

Which strand is used to make the MRNA?

Answer 10

Template (non coding) strand

Question 11

MRNA contains

Answer 11

A,U,G,C

Question 12

The process of making a protein is

Answer 12

In transcription MRNA is created from binding to DNA template strand and copying the gene and is complimentary to the DNA, with A U G C complimentary to DNA’s T A C G, mRNA moves out of nucleus and goes to ribosome and binds with it. I’m translation, tRNA which contains a amino acid and is complimentary to the mRNA bases, it pairs up with the mRNA and forms a amino acid chain which folds to create a protein
