Ligase
Join pieces of DNA together at specific sites called 'sticky ends'
1 of 20
Sticky Ends
Where pieces of DNA is joined
2 of 20
Cytoplasm
Watery jelly- most cell activities occur.
3 of 20
Mitochondria
Where aerobic respiration occur
4 of 20
Nucleus
Contains DNA
5 of 20
Cell Membrane
Controlles what goes in and out the cell.
6 of 20
Homozygous
Identical alleles
7 of 20
Phenotype
The characteristic produced by a certan set of alleles /The expressed characiteristic e.g. brown eyes, black eyes
8 of 20
Recessive allele
Describes an allele that will only affect the phenotype if the other allele is also recessive. it has no affect if the other allele is dominant
9 of 20
Heterozygous
Differend alleles e.g. Bb
10 of 20
Alleles
Most genes come in different versions
11 of 20
Dominant alleles
Describes an allele that will always affect a phenotype as opposed to a recessive allele, whose effect will not be seen if a dominant allele is present
12 of 20
Zygote
A fertilised egg cell
13 of 20
Genotype
The alleles of a certain characteristic that are found in an organism
14 of 20
Haploid
Half set of chromosomes
15 of 20
Diploid
Full set of chromosomes
16 of 20
Acrosome
Vacuole on the tip of the headto help the sperm swim into the jelly coating of the egg.
17 of 20
Main features of meiosis
Cell divides 2x forming 4 gametes / the gametes are genetically different from each other
18 of 20
Why is meiosis important for sexual reproduction
So you end up with variation twins (non-identical twins)
19 of 20
OCA2 Gene
Controles the amount of melanin produced (protein which makes hair, eyes, and skin darker in colour)
