Unit 1: DNA and the Production of Proteins Booklet Wordbank

Question 1

Base pairs

Answer 1

Bonding of complementary bases in DNA (and RNA) molecules

Question 2

Genetic code

Answer 2

Sequence of bases in a DNA molecule that determines the amino acid sequence of a protein

Question 3

Amino acids

Answer 3

The sub-units of a protein that are arranged in sequence to form a protein molecule

Question 4

Protein synthesis

Answer 4

The production of protein molecules from amino acid molecules

Question 5

Complementary

Answer 5

Bases on each strand of the DNA which are able to join together are said to be complementary

Question 6

Proteins

Answer 6

Molecules that carry out many cellular functions, made from amino acids

Question 7

mRNA

Answer 7

Molecule that carries a complementary copy of the genetic code from the DNA in the nucleus to a ribosome to be synthesised into protein

Question 8

gene

Answer 8

Section of a chromosome that contains the genetic code for a protein

Question 9

Ribosome

Answer 9

Organelle in the cytoplasm that binds mRNA and synthesises proteins using the genetic code of the mRNA

Question 10

DNA

Answer 10

Deoxyribonucleic acid. Chemical that forms chromosomes and contains genetic information of an organism

Question 11

Double stranded helix

Answer 11

Shape of a DNA molecule. Two twisted strands that are held together by complementary base pairs.
