A chromatid (Greek khrōmat- 'color' + -id) is one copy of a newly copied
chromosome which is still joined to the other copy by a single centromere. Before
replication, one chromosome is...
Chromosomes can have 1 or 2 chromatids, depending on whether they have ...
every human cell has 23 pairs of chromosomes: one chromosome from each pair
Mar 22, 2010 ... I thought one chromatid contain 1 DNA strand and 2 chromatids make a
chromosome and 1 DNA molecule. So in a ... When the cell is replicating each
chromosome has 2 dna molecules and when it is not it only has one.
Each chromosome now consists of two sister chromatids. ... separates the 23
pairs to ensure that each daughter cell has only one copy of each chromosome.
Each such pair has been painted a different color in the picture, and each
replicated chromosome is itself composed ... A single replicated chromosome
has two sister chromatids. One chromatid is shown in yellow, the other in blue. ...
It is only during the second meiotic division (during anaphase II) that they finally
After mitosis, the chromatid pairs separate, so each daughter cell gets 46
chromatids. ... So at this stage, the daughter cells get 23 chromosomes each (of
the pair of ... There's another form of cellular division, but that one is used only to
produce .... How does the cell keep the chromosome number unchanged in
Feb 5, 2011 ... Each one of the bases is chemically distinguishable from the others; as we shall
see, .... When a cell needs to produce more cells, it does so by dividing in two. ....
Sister chromatids, on the other hand, only form once a cell has ...
Note that the bivalent has two chromosomes and four chromatids, with one ... with
23 chromosomes (haploid), and each chromosome has only one chromatid.
Even if it did, the next generation would have 8 of each chromosome, and it ... the
two chromosomes from each pair, giving each gamete only one copy of each ... In
Anaphase II, the sister chromatids move apart toward opposite ends of the cell ...
My cell normally has 46 chromosomes. ... If the cell goes through meiosis (
gamete formation) each chromatid pair will pair ... When one gamete combines
with another gamete, a zygote is formed which has 46 chromosomes.
