Gene Structure -
Inheritance - Transmission of genetic information from generation to generation
Chromosomes [Located in nuclei] = Thread-like structures of DNA carrying genetic information as genes
Gene = Short length of DNA on chromosome — Contain codes for specific proteins
Alleles = Different versions of a particular gene — give all organisms their characteristics
Sex - Determined by entire chromosome pair
XX = Female
XY = Male [Since only father can pass on a Y chromosome, he is responsible for determining sex of child]
Genes and Proteins -
DNA cannot travel out of the nucleus, hence mRNA transcribes stands of it onto itself
