After S-phase, each chromosome has two chromatids. The two sister chromatids are identical copies of the chromosome that are held together at the centromere. This structure is important for ensuring accurate distribution of genetic material during cell division.
During the S phase (synthesis), chromosomes duplicate and can be called sister chromatids. Sister chromatids are exact copies of each other joined together by a centromere. As long as they are joined, they are called sister chromatids and when they are seperated, they are called chromosomes. They do not become visible until Prophase of mitosis or meiosis however. So after the S phase (which comes after G1), the number of chromatids will be twice the n number. During the S phase (synthesis), chromosomes duplicate and can be called sister chromatids.

600 because in the dictinary lots of people have been sick from the fever every year and it just increases so in 2020 more than 800,000,000,000 will have the fever witch increases our belongings so now we must go to mars based on the title What Do People Eat?? Oficially we don't know how much foood people eat in a day
A human cell after S-phase contains 96 chromatids in total and 46 chromosomes. This means that each chromosome contains 2 chromatids (called sister chromatids).

How many chromatids have one chromosome?
One chromosome consists of two chromatids connected by a centromere.
How many chromatids are visible at prophase?
It depends on the organisms. In humans there are 46 double chromosome, which are called sister chromatids. There are a total of 92 sister chromatids, which will eventually separate into individual chromosomes during anaphase of mitosis.
If you have 24 chromosomes during prophase in mitosis how many chromatids does it have?
If you have 24 chromosomes during prophase in mitosis, each chromosome consists of 2 sister chromatids connected at the centromere. Therefore, there would be a total of 48 chromatids present.
How many sister chromatids present during anaphase of mitosis?
There are a total of four sister chromatids present during anaphase of mitosis. Each replicated chromosome consists of two sister chromatids that are held together by a centromere. During anaphase, these sister chromatids separate and are pulled to opposite poles of the cell by the spindle fibers.
How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
How many chromatids in 1 chromosomes before interphase?
There are two chromatids in each chromosome before interphase, as each chromosome replicates during the S phase of the cell cycle to form sister chromatids that are connected at the centromere.
How many chromatids have one chromosome?
One chromosome consists of two chromatids connected by a centromere.
How many chromatids would you expect to find in human cells?
Human cells typically have a total of 92 chromatids, with 46 chromatids being in each set of sister chromatids that make up a chromosome pair during mitosis.
How many chromatids are involved in crossing over of a homologous pair of chromosomes?
Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis. Each homologous pair consists of four chromatids (two from each chromosome), and crossing over occurs between a pair of chromatids from each homologous chromosome. This results in the exchange of genetic material between the chromatids.
If a diploid organism has 11 chromosomes how many pairs of sister chromatids does each cell possess?
Each cell would possess 11 sister chromatid pairs, as each chromosome in a diploid organism consists of two sister chromatids.
How many chromatids are in a tetrad?
All tetrads contain four chromatids. Each "leg" is one chromatid.2Tetrad = 2 homologous chromosomes1 homologous chromosome has 2 chromatids joined together by a centromere.That means that there are four chromatids in a tetrad
A cell containing 92 chromatids at metaphase of mitosis at its completion how many chromosomes will be made?
At metaphase of mitosis, chromosomes are duplicated, so each chromatid will become a full chromosome. Therefore, with 92 chromatids, you will end up with 92 chromosomes after the completion of mitosis.
At the end of s phase each chromosome has how many coiled dna molecules?
At the end of S phase, each chromosome has two coiled DNA molecules, also known as sister chromatids. These sister chromatids are identical copies of each other formed during DNA replication in preparation for cell division.
How many sister chromatids are in a bivalent?
A bivalent contains two duplicated homologous chromosomes.
How many sister chromatids are there in a duplicated chromosomes?
There are two sister chromatids in a duplicated chromosome. Each sister chromatid is an identical copy resulting from DNA replication during the S phase of the cell cycle.
How many chromatids makes up a chromosome when a cell is ready to divide?
the correct answer is 25
