sister chromatids
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
No, sex chromosomes are not referred to as homozygous chromosomes. Homozygous chromosomes have identical alleles at a specific gene locus, while sex chromosomes determine an individual's biological sex. In humans, sex chromosomes include X and Y chromosomes.
2 different alelles - heterozygous Same alelles - homozygous
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
The stage where chromosomes shorten by condensing their nucleoprotein is called prophase during mitosis. This is when the chromosomes become visible and appear as distinct structures under a microscope.
No they are not identical
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
The chromosomes in your skin are identical to the chromosomes every other one of your body's cells with the exception of gametes. The chromosomes of your sperm and eggs have only half of the chromosomes that are found in your skin cells.
No, sex chromosomes are not referred to as homozygous chromosomes. Homozygous chromosomes have identical alleles at a specific gene locus, while sex chromosomes determine an individual's biological sex. In humans, sex chromosomes include X and Y chromosomes.
2 different alelles - heterozygous Same alelles - homozygous
Before cell division begins, each chromosome consists of two identical joined chromatids called sister chromatids. Each sister chromatid contains an identical copy of the chromosome's DNA molecule.
yes because all they are, are one chromosome divided directly in half in to 2 identical chromosomes. :-)
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
Human cells typically have 46 chromosomes, which are organized into 23 pairs. Each chromosome in a pair contains identical components called sister chromatids, which are joined together at a region called the centromere.
