What phase does chromosomes first appear to be double?
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
Do the individual chromosomes move apart in mitosis or meiosis?
Yes, in both mitosis and meiosis, the individual chromosomes move apart during cell division. In mitosis, the sister chromatids of each chromosome separate and move to opposite poles of the cell, while in meiosis, homologous chromosomes separate in the first division and sister chromatids separate in the second division.
If According to Mendel's law of segregation what happens to chromosomes during meiosis?
According to Mendel's law of segregation, during meiosis, homologous chromosomes separate so that each gamete receives only one allele for each gene. This process occurs during the first meiotic division (meiosis I), where homologous chromosome pairs are pulled apart into different daughter cells. As a result, each gamete produced contains a single set of chromosomes, ensuring genetic variation in the offspring when fertilization occurs.
What is the complicated process of chromosome separation?
Chromosome separation, or mitosis, is a highly orchestrated process that involves multiple steps. First, the chromosomes condense and align at the center of the cell. Then, they are pulled apart by spindle fibers attached to the centromere of each chromosome. Finally, the cell divides into two daughter cells, each with a complete set of chromosomes. Any errors in this process can lead to genetic abnormalities or cell death.
What occurs in mitosis that gives the new cell identical DNA?
There are several things that occur in mitosis that gives the new cell identical DNA. The chromosomes have to be doubled first and then division of the nucleus takes place to make new identical cells.

During anaphase of meiosis do the chromosomes have one or two chromatids as they move toward the poles?
During the anaphase stage of mitosis the two chromatids become separate chromosomes. The chromatids are pulled apart and move toward their centrosomes. As they move toward the poles, the centrosomes go first, followed by the chromatids, forming a â??vâ?? shape.
What is the process that pulls apart continents?
Plate tectonics. Sub layers called tectonic plates lie underneath continents move, shift, and grind against or away from each other. The actual process of pulling apart is called diverging. The super-continent Pangaea is an example of a continent that was pulled apart. First it was pulled apart into two continents that are called Laurasia and Gondwana and then was pulled farther apart into the world that we see today.

The chromosomes must be duplicated. the real answer: DNA replicates and forms tetrads
