    Unit 5 Free Response Meric Pope Meiosis 1 and Mitosis are very similar events‚ however‚ they have certain differences. One difference is crossing over. Meiosis 1 does cross over and because of that‚ it creates genetic changes. Mitosis ‚ on the other hand‚ does not cross over. Something else that is different is the way it occurs. Meiosis 1 is sexual but Mitosis is asexual. Another change is the number of divisions that each event goes through. Meiosis 1 goes through 2 divisions which ends up having

    Meiosis is extremely critical because its job is to check that all species produced by sexual reproduction include the right number of chromosomes we should have. This activity decreases the number of chromosomes in half‚ permitting the sexual reproduction process to prevail. Because meiosis produces cells that eventually becomes reproductive cells‚ this division in chromosome number is critical to the cell cycle. Without this process‚ the combination of two gametes during fertilization would result

    Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent‚ 2 chromosomes or 4 chromatids (TETRAD)‚ this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA‚ and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes

    Crossing over- The two chromosomes making up a homolog pair are not genetically identical because homologs are inherited from different parents. When the chromosomes synapse during prophase 1‚ each gene in each chromosome is brought into contact with the same gene on that chromosome’s homolog. During this process of synapses the two chromosomes of each homolog pair exchange segments of DNA in a process called crossing over. The gene combinations on a chromosome can be changed. For example‚ suppose

    Meiosis BIOL 1111 Introduction Meiosis is the second important kind of nuclear division. It resembles mitosis in many ways but the consequences of meiotic divisions are very different from those of mitotic divisions. While mitotic division may occur in almost any living cell of an organism‚ meiosis occurs only in special cells. In animals‚ meiosis is restricted to cells that form gametes (eggs and sperm). Each species has a characteristic number of chromosomes per somatic cell. Fruit flies

    Interphase: DNA replicates ( S-phase) Prophase: Nucleolus fades and chromatin (replicated DNA and associated proteins) condenses into chromosomes. Each replicated chromosome comprises two chromatids‚ both with the same genetic information. Microtubules of the cytoskeleton‚ responsible for cell shape‚ motility and attachment to other cells during interphase‚ disassemble Pro Metaphase: - nuclear envelope breaks down- no longer a recognizable nucleus. Mitotic spindle fibers elongate from the centrosomes

    Recombinant DNA Report Our final annotated gel image sums up the successful experiments we performed over the course of 8 weeks. The image will be referred to throughout the report: Lane 1: 10 µL of ladder. Lane 2: 20 µL of a pAMP- EcoRI/HindIII double digestion. Within the double digestion‚ one can find 8 µL of pAMP‚ 1 µL of the EcoRI enzyme‚ 1 µL of the HindIII enzyme‚ 5 µL of 10x Buffer 2.1‚ and 35 µL of water. A total volume of 50 µL was present

    Bio-111 Laboratory #8 Mitosis and Meiosis 17 November 2010 Part1-Questions: a) Explain mitosis Mitosis is a process of asexual reproduction in eukaryotic cells. This process is divided into five stages: prophase‚ metaphase‚ anaphase‚ telophase and cytokinesis. A diploid cell duplicates its genetic information. Therefore the two diploid daughter cells will receive an exact copy of the genetic material. Explain meiosis Meiosis is a two round cell division process where a diploid cell divides
