Define: DNA
A chemical that makes up chromosomes and carries genetic information
2 of 23
Define: Chromosomes
Consists of a string of genes
3 of 23
Define: Gene
Sections of the DNA molecule that contains instructions for specific proteins that are used in your body
4 of 23
What is a codon in DNA?
pattern in DNA e.g T C G G T C G G T C G G, there are 4 codons as TCGG has 4 letters (complimentary base pairings)

What is the Glue enzyme
DNA Ligase
6 of 23
What is the Cutting enzyme
Restriction enzyme
7 of 23
Define: Diploid
A cell or nucleus contains 2 complete sets of chromosomes, one from each parent
8 of 23
Define: Haploid
A cell or nucleus that contains a single set of unpaired chromosomes
9 of 23
Define: Fertilisation
Fertilising an egg. Fusion of male and female gametes to form a zygote
10 of 23
Define: Zygote
A diploid cell resulting in the fusion of 2 haploid gametes. A fertilised ovum
11 of 23
Define: Gamete
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
12 of 23
Define: Enzyme
A substance produced by a living organism to act as a catalyst for specific biochemical reactions
13 of 23
Define: Active site
A region on an enzyme that binds to a protein or other substance during a reaction.
14 of 23
Define: Substrate
The material or substance on which an enzyme acts.
15 of 23
Define: Denature
To take away or alter the natural qualities of an enzyme/substrate
16 of 23
Define: Respiration
The process of releasing energy from food

What is the role of Mitosis? mi2osis
To make more body cells during growth or to replace damaged cells. Body cells divide using mitosis. 2 haploid cells are produced. 2 chromosomes in each cell
18 of 23
What is the role of Meiosis? me1osis
A different kind of cell division called Meiosis is neede to product haplod gametes. 4 haploid cells produced. 1 chromosome in each cells
19 of 23
Define: Momentum
the quantity of motion of a moving body, measured as a product of its mass and velocity
20 of 23
Define: Clone
An individual created by a form of asexual reproduction to produce offspring that is generated identical to the parent. Individuals that are genetically identical
21 of 23
Define: Stem Cells
An unspecialised cell that can divide to produce more stem cells or different kinds of specialised cells
22 of 23
The difference between embryonic stem cells and adult stem cells
Embryonic stem cells have potential to develop into almost every type or human cell but Adult stem cells can only differentiate into a few types of cell
