Document Summary
Mendel"s laws (confirm unit of inheritance is discrete and stable) Law of segregation: paired hereditary units segregate during production of gametes. Law of independent assortment: paired units for distinctive traits assort independent of each other. Dna is a long series of nucleotides (made of base, sugar, phosphate; constituent units of dna) Bases form the rungs of a ladder Molecules replicate and continuously produce new dna. The code for producing all the proteins of an organism can be found in the dna of that organism. Portion of the dna unwinds and one strand is used to produce mrna. Ribosomes translate info on mrna into a chain of amino acids. The more similar the amino acid sequence of a protein the more ___ two species shared a common ancestor recently. Consequences for individuals but not for populations. Too many chromosomes in a gamete such as down"s syndrome.
