Chromosomes are distributed equally to daughter cells. 8. Protein production is high. 9. Chromosomes are duplicated. 10. DNA synthesis occurs. 11. Cytoplasm divides immediately after this period. 12. Mitochondria and other organelles are made. The following are not in the correct order. Please answer the questions below. 13.
I. G1 phase (Gap 1) - Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) - Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2) - The Cell “double checks” the duplicated chromosomes for error, making any needed repair.
A duplication is a structural change in chromosomes that causes doubling of a chromosome segment. The size of the doubled segment can vary considerably. Chromosome duplications are generally more tolerated by an organism than chro mosome deletions. Duplications can occur within a chromosome or among nonhomologous chromo
Read your text carefully, and then make a labeled sketch that shows a duplicated chromosome with two kinetochores and some attached spindle fibers. Figure 12.8 in your text will help. 23. Use Figure 12.7 in your text to help you complete this chart. Label each phase by name; then label the smaller structures.
21 paź 2024 · Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.
Centrosome and centromere are two components involved in the division of a cell. A centrosome is an organelle which is made up of microtubules. It nucleates all the microtubules inside a cell in...
20 cze 2023 · By convention the chromosomes are arranged into the pattern shown in Figure \(\PageIndex{15}\) and the resulting image is called a karyogram. A karyogram allows a geneticist to determine a person's karyotype - a written description of their chromosomes including anything out of the ordinary.
