Some Basic Terms:
DNA : deoxyribonucleic acid -- what our inherited material is made of
-- in nucleus and mitochondrionRNA: ribonucleic acid – a close
copy of DNA
Some Basic Terms:
Gene: DNA sequence coding for particular characteristic
Allele: 2 different forms of the same gene
Homozygous: two of the same allele eg: AA or aa
Heterozygous: two different alleles e.g.: Aa
Some Basic Terms:
Dominant: when allele is present it is always expressed
Recessive: need 2 copies of allele for the trait– masked by dominant
Some Basic Terms:
Autosome: non-sex chromosomes (pairs 1-22)
Sex chromosome: 23rd pair of chromosomes XX or XY
Some Basic Terms:
Some Basic Terms:
Chromatin: fibres of DNA that make up chromosomes
Chromosome: strands of nucleic acids and histone proteins
Chromatid: individual chromosome strand
