WebFigure 2. Spo11-mediated DSBs and homologous recombination pathways. (A) The Spo11 homodimer (green and gray shading) is transparent in order to see the duplex DNA underneath (red).Each Spo11 monomer attacks the phosphodiester backbone of the DNA at adjacent base pairs (yellow lines), using a catalytic tyrosine residue with assistance from … WebRight after meiosis I, the homologous chromosomes have separated into different cells. Each homolog carries one copy of the gene, and each gene could be a different allele, but these two homologs are now in two different cells.

7.3 Variations in Meiosis - Concepts of Biology OpenStax
WebA: ANSWER;- Stem cell arises from the differentiation and division of primordial germ cell in embryos.…. Q: Sketch a comparison of Metaphase Mitosis and Metaphase I Meiosis (diploid:8 chromosomes n=4) - Be…. A: Metaphase is a stage during the process of cell division (mitosis or meiosis) where all the genetic…. WebIn humans (2 n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I ( n = 23). Prophase I During prophase I, chromosomal condensation allows chromosomes to be viewed under the microscope. WebMitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell. Mitosis involves one cell division, whereas meiosis involves two cell divisions. . Sort by: ciaoticketsnew
