Premium DNA Gene Genetics
Background DNA is an abbreviation for deoxyribonucleic acid‚ but it is usually known by its initials alone. DNA is found in practically all living organisms‚ and it is now known to carry genetic information from one cell to the next‚ and from one generation to the next. The units of inheritance‚ called genes‚ are actually sections of the DNA molecule. Nuclei of the cells of higher organisms contain thread-like bodies called chromosomes‚ which consist of DNA‚ wrapped around proteins. So understanding how

Meiotic Mysteries By: Karen Schindler In class we went over the cycle of meiosis‚ the sexual life cycle‚ and its stages. Meiosis has four stages which are‚ prophase I‚ metaphase I‚ anaphase I‚ and telophase I. In an adult before ovulation the oocyte goes back to meiosis forming a meiotic spindle of microtubules to segregate homologous chromosomes. When it reaches fertilization‚ the egg itself undergoes a second round of division segregating sister chromatids. Which is Prophase II‚ Metaphase II

combines the genetic contribution of each parent into the new offspring. 2. Distinguish between asexual and sexual reproduction. Asexual Reproduction-A form of reproduction which does not involve meiosis or fertilization without fusion of gametes. Sexual Reproduction- Has two processes: meiosis‚ involving halving the number of chromosomes and crossing over to get more gene combinations and fertilization‚ involving the fusion of two gametes and the restoration of the original number of chromosomes
Free Meiosis Chromosome Mitosis
haploid cells that are produced by meiosis. Diploid cells contain two complete sets (2n) of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas. Some examples are skin‚ blood‚ muscle cells (also known as somatic cells). 2. In 2-4 sentences compare and contrast mitosis and meiosis including the steps‚ purpose and products. Mitosis and meiosis are types of nuclear division that make different types of cells. Mitosis makes diploid cells that are genetically

hormones: FSH and LH in the membranes of follicle cells FSH: • Development of oocyte in the follicle • Thickening of follicle wall • Secretion of follicular fluid • Secretion of estrogens by follicle wall LH: • Completion of meiosis in the oocyte • Partial digestion of follicle wall to allow it to open (ovulation) • Growth of the corpus luteum
Premium Meiosis Reproductive system Pregnancy
P1: Explain how sperm and ova are formed by producing an annotated diagram of meiosis and discussing what happens in ogenesis and spermatogenesis In the male‚ meiosis precedes sex cell differentiation. A single spermatogonium enters the first meiotic division as a primary spermatocyte. This division produces two secondary spermatocytes‚ each of which divides to form two haploid spermatids. Each spermatid then differentiates (by a process called spermiogenesis) into a spermatozoon by the elaboration

Mitosis Biology Project Dania Abu Zahra‚ Hadeel Kashash‚ Nada Mubarak‚ Reem Al Ahbabi What is Mitosis? Mitosis is the process by which a cell‚ which has previously replicated each of its chromosomes‚ separates the chromosomes in its cell nucleus into two identical sets of chromosomes‚ each set in its own new nucleus. It is a form of nuclear division. It is generally followed immediately by cytokinesis. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle—the division of

rest of the cell cycle and goes through the G2 phase where the cell prepares for mitosis. Mitosis is the process of division of cells in the cell cycle known as the M phase‚ this is how the cells in our body divides and grow. As the cell continues through the cell cycle to the M phase‚ here the cells goes through the stages of Mitosis and as the result it produces two diploid cells. Not every cell goes through Mitosis immediately‚ the cells need to either be told to prepare for division or it senses
