Document Summary
Bio arky lecture 2: double stranded macromolecule with a coiled double helix, deoxyribonucleic acid. A-t, c-g: complimentary structure that allows dna to replicate itself, adenine w thymine, cytosine w guanine. Mitosis: makes new somatic cells with mitosis, daughter cells are genetically identical to the parent cells, not a factor in evolution of a species. Meiosis: meiosis makes gametes (sex cells, takes mitosis one step further and creates cells with half the number of chromosomes found in somatic cells, i. e. the haploid number. Includes a second cell division that is not preceded by dna replication: diploid number of chromosomes will be reconstituted when two sex cells meet, i. e. sperm and ovum. The laws of inheritance & gregor mendel. 1865 proves that traits do not blend of polymorphic traits) Also finds some traits are dominant and the other ones are recessive (types. Groups of traits are not necessarily inherited (law of independent.
