ANT 101 Lecture Notes - Lecture 8: Dna Replication, Cell Division, Meiosis
Document Summary
Two strands od the double helix separates as well as the hydrogen bonds and then the floating nucleotides attach to the new bases. The two separate sands with the base pairs attach to the newly separated helix. Sugar and phosphates of the nucleotides bond together until there are two new strands of dna until one new strand has one of the original and a new strand. When you have your cells divide during mitosis each new cell needs some. What kinds of cells replicate during mitosis. This only happens when the dna replicates. In a real human cell the original cell will have 23 pairs of chromosomes. In the duplicated cell there are 46 pairs. All 46 line up in a single line down the middle. The spindles fibers begin to pull apart the chromosomes and the original and. Each new cell has 46 (single) un-duplicated chromosomes or 23 pairs.
