What phase of mitosis is it when chromosomes align on the spindle equator?
The phase of mitosis when chromosomes align on the spindle equator is called metaphase. During this stage, the chromosomes, which have already been duplicated and condensed, are positioned along the metaphase plate, ensuring that each sister chromatid is attached to spindle fibers from opposite poles. This alignment is crucial for the accurate separation of chromosomes in the subsequent phase, anaphase.
When is the S phase completed?
when each chromosome has been duplicated
What period of meiosis in which the cell replicates its chromosomes?
The period of meiosis in which the cell replicates its chromosomes is called interphase, specifically during the S phase (synthesis phase) of the cell cycle. This occurs before meiosis begins and ensures that each homologous chromosome has been duplicated, resulting in sister chromatids. Following interphase, meiosis proceeds with two rounds of division: meiosis I and meiosis II.
Why are chromosomes called doubles chromosomes just before mitosis begins?
Amount of DNA that has been doubled
How many chromosomes does a human cell that has been produced by the process of meiosis have?
After meiosis 2 in human cells are 23 chromosomes. Meiotic division occur only in reproductive cells because when spermatozoid and ovum combine they form again 46 chromosomes(23 pairs of chromosomes).
When is s phase complet?
S phase is complete when each chromosome has been duplicated.

When is Cytoplasm is divided?
Cytoplasm is divided during cytokinesis, which is the final stage of cell division. This process occurs after the duplicated chromosomes have been segregated into two daughter cells during mitosis or meiosis.
How many chromosomes are in a egg cell of a sheep?
it all depends on the zygote which has not been able to find out the total chromosome's in the zygote.
When a chromosome has been duplicated it consists of two identical pieces attached together called?
Oh honey, it's called a "sister chromatid." Think of them as the ultimate BFFs, always sticking together through thick and thin. So next time you see those duplicated chromosomes, just remember they're twinning like there's no tomorrow.
When is the S phase completed?
when each chromosome has been duplicated
When is Phase complete?
S phase is complete when each chromosome has been duplicated.
What chromosomes are linked in the case of psoriasis?
Psoriasis has been linked to several chromosomes, particularly chromosome 6, which contains the major histocompatibility complex (MHC) region associated with immune response. Additionally, susceptibility loci have been identified on chromosomes 1, 4, 17, and 19. These genetic associations suggest a complex interplay of multiple genes and environmental factors in the development of psoriasis.

What is the purpose of a clonic?
A clonic copies as in the case of a clone. A clonic indicates that the object is not an original and has been copied or duplicated. A clonic is not the same as the original and there is always differences in the original and what has been copied. The root word of clonic is clone which means that an item has been duplicated or made from an original copy.
Once a chromosome has been duplicated the two identical portions that are attched by their centromere are know as what?
chromatids.
It is not easy to observe individual chromosomes during interphase because?
the DNA has not been duplicated yet. they have uncoiled to form long, thin strands. they leave the nucleus and are scattered throughout the cell. homologous chromosomes do not pair up until division starts.
