MITOTIC CELL DIVISION

MITOTIC CELL DIVISION. JANUARY 7, 2011 LAB JANUARY 13, 2011. In eukaryotic cells the genetic material is organized into a complex structure composed of DNA and proteins and localized in a specialized compartment, the nucleus.

B2 Revision

B2 Revision. Topics 1-4. DNA - . Genes are made of a chemical called DNA. In DNA there 4 bases called Adenine, Cytosine, Thymine and Guanine DNA contains instructions for making the cell and telling it what to do.

Lab Activity 35

Lab Activity 35. Embryology. Portland Community College BI 233. Spermatogenesis. Oogenesis. Fertilization. An egg must be fertilized within 12 to 24 hours of ovulation It takes about 72 hours for an egg to reach the uterus. The sperm must encounter the egg somewhere in the uterine tube.

Meiosis

Meiosis. The process of creating sex cells. What is Meiosis?. Meiosis involves two successive nuclear divisions that produce four haploid cells. The first division (meiosis I) is the reduction division; the second division (meiosis II) separates the chromatids. . Advantages of Meiosis.

Getting to the right site:

Getting to the right site:. Helping the sperm: At ovulation, the cervical mucus increases in amount and becomes less thick, allowing easier sperm transport. Passage of the sperm through the uterus and oviduct occurs mainly due to muscular contractions of these organs. Oocyte:

Did YOU MISS A SKETCH OR TWO??

Here are some slides from Lab #12. Many students were very much into detail on Thursday not and did not see one or two slides?? Maybe. Possible?? Or Maybe Not! Regardless, I am being very generous and providing you with this PowerPoint.

Asexual Reproduction

Asexual Reproduction. Sea Star. If asexual reproduction involves mitosis, how would the parent cell compare to the daughter cell?. Asexual Reproduction. Asexual reproduction = cloning Involves only one parent Parent and offspring are identical (DNA is exactly the same)

Human Development

Human Development. Fertilization. Must occur within 24hrs postovulation Requires capacitated sperm (6-8hrs) Secondary oocyte completes Meiosis II once sperm enters oocyte Zygote formed with fusion of male and female pronuclei. Cleavage. Rapid mitotic cell division of zygote
