NO,in place of histone protien prolamin is present which act as histone analog in prokaryotes.
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
They are separated in Anaphase I of Meiosis I.
The two copies of each chromosome in body cells are called homologous chromosomes. These chromosomes are similar in size, shape, and genetic content and are inherited from each parent.
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.
The cells that have pairs of homologous chromosomes are called diploid cells.

No
No they are not. Chromosomes [homologous or (occasionally) not] make Lungs. The Nuclei of Lung Cells also make Chromosomes.
A diploid cell has homologous chromosomes. Diploid cells contain two sets of chromosomes, with one set inherited from each parent. The homologous chromosomes have similar genes in the same order, but may have different versions of those genes.
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Human cells have 23 homologous pairs. They also must go through meiosis before that. Females have 2 X chromosomes, while Males have an X and a Y chromosome. That's why the males cells decide the gender of the child.
Yes, DNA is present in both prokaryotic and eukaryotic cells. In prokaryotic cells, DNA is found in a circular form in the nucleoid region, while in eukaryotic cells, DNA is located in the nucleus and organized into linear chromosomes.
They are separated in Anaphase I of Meiosis I.
