Document Summary

Genes > the functional units of heredity; they are composed of dna and specify the structure of proteins. Chromosomes > rod-shaped structures within every body cell that carry the genes. Dna > the chromosomal molecule that transfers genetic characteristics by way of coded instructions for the structure of proteins. Genome > the full set of genes in each cell of an organism. Never change fixed from the moment of conception. Can be altered by other genes, environment. E. g. , how tall you can grow vs. how tall you actually grow. Every cell has 46 chromosomes (23 pairs) Combine to form new cell with 46 chromosomes. Heredity encoded in combination of bases, adenine, thymine, guanine, and cytosine. Genes contain bases, carry codes for protein manufacture. Dominant gene: if a person receives a dominant gene from either parent, they will display the characteristic the gene controls.
