The process of using the information on the gene to make a protein | Gene expression |
The process of breaking down glucose into pyruvic acid | Glycolysis |
Anaerobic respiration | Fermentation |
The fusion of 2 (haploid) gametes to for a (diploid) zygote | Fertilisation |
A haploid sex cell which is capable of fusion | Gamete |
A unit of DNA which codes for the production of a specific protein | Gene |
Has different alleles (for a trait) | Heterozygous |
has identical alleles for a trait | Homozygous |
A biological catalyst which is fixed to an inert material by chemical or physical means | Immobilised Enzyme |
The genetic make-up of an individual | Genotype |
The passing on of traits from parent to offspring by means of genes | Heredity |
Genes located on the same chromosome ( are said to be linked) | Linkage |
Manipulation or alteration of genes | Genetic Engineering |
Having one set of chromosomes | Haploid number |
During gamete formation each member of a pair of alleles may combine randomly with either of another pair | Mendel's 2nd Law the law of independent assortment |
All the chemical reactions that occurs in organisms | Metabolism |
Neither allele masks the expression of the other | Incomplete Dominance |
A form of nuclear division in which one(diploid)nucleus divides to form four different(haploid) (daughter) nuclei | Meiosis |
A form of nuclear division in which one nucleus divides to form 2 identical (daughter) nuclei | Mitosis |
Traits are controlled by pairs of alleles which separate at gamete formation. each gamete carries only one allele for each trait. | Mendel's first law the law of segregation |
