If we use the word "chromatid", there are always two. (As with twins!)
In a eukaryotic cell immediately after cell division (mitosis or meiosis), each chromosome contains only one DNA molecule.
If the cell is preparing for a subsequent division, then midway through interphase the DNA replicates. Now there are two molecules of DNA in each chromosome.
At the start of the following division, in prophase, the chromosomes condense, and the two DNA molecules, with their many associated proteins, become visible under a light microscope as sister-chromatids.
What else can I help you with?
How many chromosomes does each the male and female reproductive cell contain?
Male reproductive cells (sperm) contain 23 chromosomes, while female reproductive cells (eggs) also contain 23 chromosomes. When these two cells combine during fertilization, the resulting zygote will have a total of 46 chromosomes - 23 from each parent.
What do chromosomes contain that control the characteristic of the cells?
genes
Haploid cells are cells that have?
Haploid cells are cells that contain one set of chromosomes, meaning they have half the number of chromosomes as a diploid cell. In humans, haploid cells are sperm and egg cells, which contain 23 chromosomes each. During fertilization, a haploid sperm cell and a haploid egg cell combine to form a diploid zygote with 46 chromosomes.
What type of cells contain only one set of chromosomes instead of two?
Gametes, also called sex cells, or sperm and egg cells, contain only one set of chromosomes.
Do you body cells of humans have 46 pairs of chromosomes?
A cell that contains both copies of each chromosome is called a Diploid cell.
How many pairs of chromosomes do human somatic cells contain?
Human somatic cells contain 23 pairs of chromosomes, for a total of 46 chromosomes.
Does somatic cells contain sex chromosomes?
Yes, somatic cells contain sex chromosomes. In humans, somatic cells typically contain 23 pairs of chromosomes, including one pair of sex chromosomes (XX in females and XY in males).
What cell types contains the least number of chromosomes?
Sex cells contain half the number of chromosomes that body cells contain.
Are homologous chromosomes present in diploid or haploid cells?
Homologous chromosomes are present in diploid cells, which contain two sets of chromosomes (one inherited from each parent). In contrast, haploid cells contain only one set of chromosomes.
How many chromosomes does each the male and female reproductive cell contain?
Male reproductive cells (sperm) contain 23 chromosomes, while female reproductive cells (eggs) also contain 23 chromosomes. When these two cells combine during fertilization, the resulting zygote will have a total of 46 chromosomes - 23 from each parent.
Through the process of meiosis sex cells are produced that are?
Haploid cells, as opposed to diploid cells. Haploid cells contain only 23 chromosomes, but normal diploid cells contain 46 chromosomes.
How many chromosomes do the sperm cells contain?
23
What do chromosomes contain that control the characteristic of the cells?
genes
Differentiate between diploid and haploid cells.?
Diploid cells contain 2 complete sets of chromosomes, one from each parent. an example would be somatic cells. Haploid cells are cells that contain 1 set of unpaired chromosomes of half the number of chromosomes as a somatic cell.
Differentiate between diploid and haploid cells.-?
Diploid cells contain 2 complete sets of chromosomes, one from each parent. an example would be somatic cells. Haploid cells are cells that contain 1 set of unpaired chromosomes of half the number of chromosomes as a somatic cell.
How many chromosomes are typically found in human somatic cells?
Human somatic cells typically contain 46 chromosomes.
Which cells contain only sex chromosomes?
