What is a B chromosome? Early definitions revisitedDEFINITIONSCHROMOSOMESSince the discovery of B chromosomes, multiple different definitions of these selfish genetic elements have been put forth. We reconsidered early definitions in light of recently published studies. While there are many characteristics ...
What is the importance of chromosomes to a cell? Chromosome condensation: Chromosomes appear for a cell division (either mitosis or meiosis). They are condensed from DNA by the DNA wrapping first around histones to form a chromatosome. These further coil around themselves and are compressed to ...
Another difference between the stages of mitosis and meiosis is that in meiosis, homologous chromosomes pair up during metaphase instead of chromatids. In a homologous pair, one chromosome comes from the mother, and one chromosome comes from the father. Homologous chromosomes are very similar, but...
. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit within a cell's nucleus. Condensed chromatin fibers form chromosomes....
The life of a human being begins as a single celled zygote. The information presents in the chromosomes in this cell is what determines the characteristics of this human being. Each cell in the body of a male contains one X chro mosome and one Y chromosome (XY). Read the passage and...
Since many laypeople (including lawyers and judges) falsely assume that sex can be reduced to chromosomes, it is especially important to avoid reinforcing this assumption. Therefore, in explaining the sex assignment of a person with 46,XX congenital adrenal hyperplasia, avoid...
A complete definition of biological sex should include male, female, and intersex. What is biologicalsex? It seems like a question with an obvious answer: male and female, of course. You might point to internal or external sex organs, or sex chromosomes (XX for females, XY for males), or...
to be possible, both the male and female gametes must possess half as much genetic material as the rest of the cells of the organism. Therefore the spermatozoon is known as ahaploid cell. Haploid cells have half the chromosomes (one of each pair), and in humans this is 23 chromosomes. ...
