Chromosomes are made of this material?
Chromosomes are made up of DNA and proteins. The chromosomes help to carry the genetic information throughout the body. There are 23 pairs of chromosomes in the human body.
Yes, chromosomes are made of DNA and protein molecules called histones. Edit from another user: False, they're made of material called chromatin. Edit from user #3: Chromosomes and chromatin are actually the same thing, except in different form. Both chromosomes and chromatin are made up of a strand of DNA wrapped around histone protein, except chromatin is in a long and stringy form while chromosomes are a compacted and twisted version of chromatin.
Sperm and ova are made through a process of cell division called meiosis. Meiosis halves the genetic material in cells. Both sperm and egg cells have half the chromosomes of a normal cell; but when they combine, the full number of chromosomes will be restored. Sperm are made in the testes. Ova are made in the ovaries.
What is the genetic material contained in each of the 46 chromosomes of a human cell just before division?
Chromosomes are structures made of DNA and proteins (specially histones). They are the genetic material which regulates all the cell activity and contain the hereditary information . They contain the information for protein synthesis and so on. Chromosomes are contained within the nucleus. So any cell which has metabolic activity and has a nuclei contains chromosomes. Since plants are living beings they surely have "working cells" with nuclei and chromosome's. If they didn't have any…
