Species |
Organisms capable of interbreeding and producing fertile offspring |
Heredity |
The passing on of traits from parent to offspring by means of genes |
Gene Expression |
The process of using the information on the gene to make a protein |
Gene |
A unit of DNA which codes for the production of a specific protein |
DNA profiling |
Examining DNA / for a pattern or band / to compare OR A method of making a unique pattern of bands from the DNA of a person(, which can then be used to distinguish that persons DNA from other DNA) |
Coding DNA |
That part of the chromosome which carries the information to make a protein |
Non-coding DNA |
That part of the chromosome which doesn’t carry the information to make a protein |
Genetic screening |
Testing (people) for the presence of a (specific) gene or to establish presence or absence of gene(s) |
Transcription |
The process of producing mRNA using DNA as a template |
Translation |
The process of making a protein using the mRNA code as a template |
Gamete |
A haploid sex cell which is capable of fusion |
Fertilisation |
The fusion of 2 (haploid) gametes to form a (diploid) zygote |
Allele |
An alternative form of a gene |
Homozygous |
Has identical alleles (for a trait) |
Heterozygous |
Has different alleles (for a trait) |
Genotype |
The genetic make-up of an individual |
Phenotype |
Physical appearance of an organism |
Dominance |
One allele masks the expression of the other |
Recessive |
Allele whose expression is masked by dominant allele |
Incomplete Dominance |
Neither allele masks the expression of the other |
Variation |
Difference between members of species or population |
Mutation |
Change in the genetic make up |
Genetic Engineering |
Manipulation or alternation of genes |
Evolution |
(Inheritable) change within a population (or species) / in response to change in the environment / by natural selection / overtime |
