Chromosomes are molecules inside the nucleus of a cell, and they carry the genes that have been passed down from the parents. They are actually composed of protein and DNA. With normal development, all the cells in the human body contain the same number of chromosomes....
cell division is more complicated because the genetic material is located on CHROMOSOMES inside the nucleus, being composed of two distinct processes that usually occur together; (a) nuclear division (MITOSIS producing two identical nuclei, or MEIOSIS producing four nuclei with a halving of the genet...
The Genes You Don't Get From Your ParentsOctober 06, 2021 (via TEDEd) Inside our cells, each of us has a second set of genes completely separate from our 23 pairs of chromosomes. And this isn’t just true for humans— it’s true of every animal, plant, and fungus on Earth. This...

Is this number always the same? Chromosomes: The chromosome is simply the DNA molecule that carries the genetic make up (genome) of a cell. Chromosome plays an important role during meiosis and subsequent sexual reproduction, enabling the transfer of genetic make up...
the absence of signalling inside the sex chromatin being evident. Note that the position of the autosomal synaptonemal complexes appears in focal plains that are different from those occupied by the sex chromosomes. On the contrary, in the right reconstruction, in which the SMC3 subunit of the ...
Boeke’s team did something similar. Yeast’s chromosome III contains TAG stop codons, which Boeke’s team replaced with TAA stop codons, so the TAG could now potentially be used to do something else. “You can make all kinds of unnatural things inside of cells by tweaking proteins to do...
Presence of dioecy is indicated by X inside a square. Filled symbols indicate taxa in which sex chromosomes have been studied. Black indicates the presence of species in which heteromorphic sex chromosomes have been found, either cytologically or by genetic mapping, and grey indicates that sex ...
