Document Summary
Mitosis: cellular division resulting in 2 identical daughters cells with the same number of chromosomes as the parent cell. Meiosis: cellular division resulting in each daughter cell receiving half of the amount of dna as the parent cell. Rungs of dna ladder are composed of 4 nucleotide bases: adenine (a), cytosine (c), guanine (g), and thymine (t) Nucleotide: building block of dna, consisting of a base, sugar, and phosphate group. Each rung is composed of 2 possible combos (a-t) or (c-g), as the 4 bases don"t always meet with each other, but with their opposites. Contains the genetic blueprint necessary for specifying the: function of dna: sequence of amino acids that compromise proteins, formation of proteins: Translations: process during which the info in mrna molecules is used to contrast proteins: translations involve mrna, ribosomes, trna and amino acids. Blueprint (nucleotide sequence) trna (factory workers) and amino acids (building materials)
