Document Summary
Chapter 5: genetics and the development of the human brain. Strand of dna transcribes itself into a complementary chain of rna: each set of 3 bases (a codon) instructs a ribosome to make a particular aa, amino acids are linked together to form a protein. Identifies the characteristics that defines a species eg entire human genome. Identifies genetic basis for individual characteristics eg. having. 1 allele for blue eyes and a 2nd allele for brown eyes. Bodies found within the nuclei of cells that are made up of dna. Functional hereditary unit occupying a fixed location on a chromosome. Cell division in sexually reproducing organisms that reduces the # of chromosomes to half in reproductive cells such as sperms, eggs an spores. Change on a gene/chromosome that can be passed to offspring. Variations that occur in a gene when a single base is changed from 1 version to the next.
