BIO 111 Chapter Notes - Chapter 7: Wasatch Range, Asexual Reproduction, Dna Replication
Document Summary
7. 1: different life cycles use different modes of cell reproduction. Cell division a process by which a parent cell duplicates its genetic material and then divides into two similar cells. Important for growth, repairing tissues, and reproduction of all organisms. Asexual reproduction through binary fission and mitosis: asexual reproduction a rapid and effective means of making new individuals, daughter cells are clones of the parent cell when without mutations. Mutations are alterations in dna sequence caused by environmental factors in dna replication and allows for variation: reproduce through binary fission for prokaryotes, mitosis for eukaryotes, some multicellular eukaryotes can reproduce asexually. Aspen trees can reproduce sexually and asexually but most of the ones in the wasatch mountains are just clones of each other because they reproduced asexually. This genetic material is dna that is organized into chromosomes. Most cells (somatic cells) are not specialized, but the gametes are special because they have only half the chromosomes as somatic cells.
