What are chromosomes made up of?The Chromosomes:Chromosomes are found in the nucleus of every cell from living things. They are the genetic material that gets replicated during the life cycle of a cell such as during the phase of cell division. When a cell divides, new cells are formed, ...
(a) What are chromosomes made of? (b) Compare and contrast mitosis and meiosis. Cell division: After undergoing prophase, metaphase, anaphase, and telophase, the cell divides into two daughter cells with the chromosomal contents of the parent. The chromosomes are the components th...
In mitosis, the diploid “parent” cell divides and produces two diploid “daughter” cells. However, in meiosis, the parent cell produces four haploid daughter cells (each containing half of the parent cells chromosomes, or 23 chromosomes). The critical difference between mitosis and meiosis is ...
Staining of polytene chromosomes with antibodies against various dREAM subunits showed extensive colocalization between these subunits. However, using an antibody against phosphorylated RNA polymerase II showed there was no overlap between the two staining patterns, which indicates that dREAM complexes associa...

the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including ...
Composition and Structure of ChromosomesChromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). In prokaryotes (e.g. bacteria), on the other hand, ...
What is the role of the nucleus in cell division? The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process ...
Cytokinesis – This procedure is the separation of the two daughter cells. A fiber ring made up of actin (protein) forms around the centre of the cell and pinches the cell to make it split into two diploid (46 chromosomes) daughter cells. ...
