Honors Bio. A single molecule of DNA has 1,000’s of genes! A single strand of DNA ~5cm long Each somatic cell has 46 molecules of DNA › 5cm x 46.
Biology B Final Exam Review. Explain the purpose of DNA replication and the steps involved. Where in the cell does it occur? Purpose: Purpose: Ensure.
DNA and The Cell Cycle. Forms of DNA DNA + Proteins = Chromosomes Most of the time, DNA is “unspooled” into loose strands – called chromatin – can be.
Cell Cycle and Cell Division. Cell Division Creates two identical “daughter” cells roughly ½ the size of the parent cell Before the cell divides: – DNA.
