What stage of mitosis takes the shortest?
anaphase
What stage is observed most frequently in mitosis?
metaphase
What is the relationship between DNA Chromatin and Chromosomes?
​Chromatin Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell’s genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
Why is it important for DNA to condense into chromosomes?
During mitosis, the chromosomes condense so that each chromosome is a distinct unit. Prior to mitosis, the cell copies its DNA so that it contains two copies of each chromosome. Condensing the DNA into tightly packed chromosomes makes the process of chromosome alignment and separation during mitosis more efficient.
What is the difference between a chromatin and a chromatid?
As mentioned above, chromatin is composed of DNA and histones that are packaged into thin, stringy fibers. The chromatin undergoes further condensation to form the chromosome. A chromatid is either of the two strands of a replicated chromosome. Chromatids connected by a centromere are called sister chromatids.
What form is DNA in during all the stages of mitosis?
After DNA replicates and the cell is about to divide, the DNA condenses and coils into the X-shaped form of a chromosome. Each chromosome actually consists of two sister chromatids, which are joined together at a centromere. Mitosis is the process in which the nucleus of a eukaryotic cell divides.
What is chromatin material and how does it change before the cell division?
The chromatin is the genetic material stored in the nucleus. The histones helps in organizing the DNA into structure called as nucleosome by the base to which the DNA is wrapped around. The chromatin condense so as to facilitate the separation and distribution of genetic material to daughter cells during cell division.
