1. how a gene becomes a trait – steps, what proteins do in your body, why protein shape is important
|
Transcription -> Translation
the shape of the protein molecule is what allows it to do its unique job |
|
|
Definition of genetics, gene, allele, homologous chromosomes, homozygous, heterozygous, dominant, recessive, genotype, phenotype
|
Genetics: the branch of biology that studies heredity and variation in organisms
Gene:Segment of DNA Allele:One of a number of alternative forms of the same gene occupying a given position on a chromosome Homozygous: Having one dominant or non-dominant parts of a trait Heterozygous: Having both dominant and non-dominant parts of a trait Recessive: The trait that is non-dominant Genotype: How a trait is put together Phenotype: How a trait shows up in a person |
