PPT-CENTROMERE It is the part of the chromosome where the kinetochore binds.

It is the part where the spindle fibers bind during metaphase and anaphase stage The centromere consists of CEN DNA consisting of 120 nucleotide pairs CENTROMERE It has three kinds of sequences. and how is it arranged!. Mike . Clark, M.D.. Amount of Genetic Material in a Cell. Before we discuss mitosis or meiosis – let’s examine how much genetic material is in a cell.. There are two divisions of cells in the human body- somatic cells and gametes (sex cells). Mike Clark, M.D.. Mitosis . technically is the process that duplicates a cell’s nucleus. The process of mitosis is . conventionally divided into . four . phases:. Prophase. Metaphase. Anaphase. Telophase. ( 1856-1921) . CHROMOSOME. Ananda. Kumar . Saha. Department of Zoology.

Sex chromosomes are chromosomes that determine the sex of an organism, and they may also carry genes for other characteristics. . In humans, each cell normally contains . 23 pairs of chromosomes,. for a total of 46. . Twenty-two . (22) . of these pairs, called . autosomes. , look the same in both males and females. The . 23rd.
