BIOL 1201 : Exam 3 Day 1 And 2
Document Summary
Cells need to possess the genetic material characteristic of the organism: genetic material is dna, the daughter cells need to complete the genetic compliment. Ex: the genetic material of prokaryotes is: circular dna. Prokaryotes: circular strands of dna, replicate the dna and pass it onto the daughter cells, division by binary fission, figure 12. 12-1. Eukaryotes: a problem, genetic material is found in linear chromosomes, linerar strands of dna, dhf. Cell division: mitosis: reproduction, growth, repair, produce daughter cells with identical genetic compliments, occurs in somatic cells. Somatic cells: all body cells except cells which give rise to gametes, gam- Chromosomes: complex of linear strand of dna and protein, each eukaryote species has a characteristic number. Chromatin: the long linear strand of dna. Identical copies of dna: attached at specialized reg???? called centromere. Ex: how many centromeres per chromosome: 1. Ex: how many centromeres per chromosome consisting of 2 sister chromatids: 1.
