Question 1

What are the 3 key parts of a nucleotide?

Answer 1

• Phosphate
• Sugar
• A base

Question 2

Where is the DNA contained?

Answer 2

DNA is contained inside chromosomes.

Question 3

How many bases code for one amino acid?

Answer 3

3 bases code for one amino acid.

Question 4

What is a nucleotide?

Answer 5

A protein’s shape is decided by the different combination of amino acids that will bond together differently.

Question 6

What is transcription?

Answer 6

Transcription is the creation of mRNA inside the nucleus.

Question 7

How does transcription work?

Answer 7

During transcription, a part of the DNA is split and mRNA is created based on one strand (using opposite bases). T is replaced by a U in mRNA.

Question 8

How does mRNA leave the nucleus?

Answer 8

mRNA leaves through a nuclear pore.

Question 9

Where does mRNA go after leaving the nucleus?

Answer 9

mRNA leaves the nucleus and enters the cytoplasm. It will then find a ribosome.

Question 10

What is a set of 3 bases in mRNA called?

Answer 10

3 bases in mRNA is called a codon.

Question 11

What composes tRNA?

Answer 11

tRNA is made up of an amino acid and an anticodon.
