Gametes are produced by what process? Gametes: Gametes are haploid sex cells. The male gamete, sperm is produced from the testes and the female game ovum is produced from the ovary. The fusion of gametes results in the formation of a zygote. Answer and Explanation:1 Gametes are produced by...
What occurs during cytokinesis? a. cell growth b. DNA synthesis c. chromosomes separate d. the cell splits into 2 What are that genes that stay together during cell division called? In what phase of the cell cycle does DNA replication occur?
The conditions re reviewed that must be met by any model of long distance attraction and transport of homologous chromosomes to the points of intimate DNA synapsis. A proposal for possible mechanisms is presented. It includes transcription and repair factors acting on coding sequences as a ...
During telophase, the chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form. What happens to the centrosome in anaphase? During anaphase, the “upward phase,” the cohesin proteins degrade, and the sister chromatids separate at the centromere. ...
During the first division of meiosis, a) chromosomes separate at the centromere b) homologous chromosomes separate c) chromosomes become triploid What are the types of cell divisions in asexual reproduction? What are the two types of cell division?
Consists of three stages: Gap 1 (growth), S phase (DNA replication) and Gap 2 (continues growth, prepares for cell division). Prophase – Chromosomes condense. Mitotic spindle forms. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids separate from one another...
division. Any failure ofhomologous chromosomesor chromatids to separate correctly is known as nondisjunction. Nondisjunction occurs during anaphase of mitosis or either stage of meiosis. Half of the resulting daughter cells from nondisjunction have too many chromosomes and the other half have none at ...
At which phase of mitosis do the sister chromatids become daughter chromosomes? Does nondisjunction occur in mitosis? If nondisjunction occurs at anaphase 2, what fails to separate? A. 2 daughter cells B. pair of homologous chromosomes C. sister chromatids D. nuclea...
Prophase I is, in my opinion, the coolest phase of meiosis. The 46 chromosomes in your body’s diploid cells are organized into 23 homologous pairs. One chromosome in each of these pairs is from your mom, and the other one is from your dad. Prophase in mitosis and prophase I of meiosi...
