Document Summary

The functional units of hereditary; they are composed of dna and specify the structure of proteins: chromosomes. Rod-shaped structures within every body cell that carries 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. Can be altered by other genes, environment. E. g. how tall you can grow versus how tall you actually grow: chromosome. Contain genetic blueprint: every cell has 46 chromosomes (23 pairs, exceptions is egg and sperm. Combine to form a new cell with 46 chromosomes: heredity encoded in combinations of bases adenine, thymine, guanine and cytosine, genes contain bases, carry codes for protein manufacture. Mapping the genetic code: human genome project: more than 75 genes that contribute to hereditary diseases have been identified. Inserted into a host cell: gene knockout. Particular function of gene is eliminated: problem. Few behaviors are controlled by single gene.
