Chapter 12

Chapter 12. The Cell Cycle. Mitosis. Mitosis is the division of the nucleus into two genetically identical daughter nuclei. The result is two cells that are exactly alike--clones of one another. Mitosis.

The Nature of Heredity

The Nature of Heredity. SBI3U0. Heredity. Genetics The study of heredity and variation Heredity refers to the fact that an individual can inherit traits from its parents You will share characteristics with your parents If your parents have black hair, you will likely have black hair

cell division: meiosis

cell division: meiosis. biology 1. Offspring acquire genes from parents by inheriting chromosomes Two general strategies Sexual reproduction Asexual reproduction Fertilization and meiosis alternate in a sexual lifecycle Meiosis reduces chromosome number from diploid to haploid

Meiosis I and II Stages

Meiosis I and II Stages. December 9, 2011. Meiosis I. PROPHASE I :. Synapsis : homologous chromosomes come together & line up side by side Crossing-over : Exchange of genetic info between non-sister chromatids occurs at the chiasmata. Centrioles start to move to the poles.

The cell cycle and mitosis

The cell cycle and mitosis. Cells constantly reproduce exact duplicates of themselves. Why? Replacement Repair Growth. Cells must make an exact copy of their DNA DNA is the blueprint of the cell and is found in the nucleus.

The Cell Cycle

The Cell Cycle . Test Review. 1. Which of the following is not a reason cells divide?. Cells divide to reproduce asexually. Cells divide so a multicellular organism can grow and replace lost cells. Cells divide when they come in contact with other cells.

Mitosis vs. meiosis

Mitosis vs. meiosis. Prophase vs. prophase i. similarities. differences. Homologous chromosomes pair up Crossing-over occurs. Nuclear membrane disappears Spindle forms Chromosomes condense and become visible. Metaphase vs. metaphase i. similarities. differences.

Review of Cell Cycle

Review of Cell Cycle. I play music at the club. Name the 3 Parts of the Cell cycle. 1) Interphase: Gap 1 : growing, carying out normal cell function. Synthesis: copies its DNA in preparation for cell division Gap 2: Cell prepares for division of the nucleus

Early prophase

Early prophase. The replicated chromosomes coil up into X-shaped chromosomes and become visible under a light microscope. The nucleolus will disappear, and the nuclear membrane will begin to break down. Late prophase.
