Nucleus
contains chromosomes on which genes are located
1 of 14
Gene
a section of a molecule of DNA and that codes for a specific protein
2 of 14
DNA molecule
two strands coiled to form a double helix, the strands being linked by a series of paired bases; A with T and C with G
3 of 14
Alleles
an alternative form of a gene which give rise to differences in inherited characteristics
4 of 14
Dominant
An allele that sways exerts its full effect on the phenotype
5 of 14
Recessive
an allele that can be 'over powered' by dominant alleles. Only seen if there are 2 recessive alleles in the genotype
6 of 14
Homozygous
a genotype in which two alleles are the same
7 of 14
Heterozygous
a genotype in which two alleles are different
8 of 14
Phenotype
how the genotype is expressed
9 of 14
Genotype
the two alleles that together make up one gene
10 of 14
Random fertilisation
produces genetic variation of offspring
11 of 14
Human Cells
Diploid Number 46 Haploid Number 23
12 of 14
Mutation
Rare and a random change in genetic material that can be inherited. Many harmful but some beneficial
13 of 14
Resistance to antibiotics
increase bacterial populations and can lead to infections difficult to control
