Is chromosome Y an acrocentric chromosome?

A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.


Why are chromosomes replicated before Mitosis but not prior to Meiosis II?

Chromosomes are replicated before Mitosis to ensure each daughter cell receives a complete set of genetic material. In Meiosis II, chromosomes are already duplicated from Meiosis I, so replication is not needed to maintain the proper chromosome number.


What part of the cell structure controls replication of chromosomes prior to cell division?

The nucleus of the cell contains the genetic material, including chromosomes, and it plays a critical role in controlling replication prior to cell division. Within the nucleus, specialized structures such as the nucleolus and proteins involved in DNA replication help regulate the process of chromosome duplication.


In phases of mitosis how many chromosomes does the parent cell have during prophase at the start of mitosis?

During prophase at the start of mitosis, the parent cell has a diploid number of chromosomes, which consists of a complete set of chromosomes from both parents. This means that if a human cell has 46 chromosomes prior to mitosis, it would have 46 chromosomes during prophase as well.


How many chromosome are in the original cell compared to those in the new cells formed by cell division?

In Mitosis when only 2 cells are formed out of one the number of chromosomes is the same in Meiosis when ultimately 4 new cells are formed the number of chromosomes is also the same, HOWEVER these chromosomes each contain half the number of genes as theses cells are gametes

What is metaphase plate?

A disc extending across the nuclear area on which the chromosomes are found at the meraphase just prior to separation of the chromosome during mitosis.


Why are there two chromatids of each color what must have happened to each chromosome prior to mitosis?

During interphase before mitosis, each chromosome replicates to form two identical sister chromatids. This ensures that each daughter cell receives a complete set of genetic information during cell division.


When does a chromosome first become visible in mitosis?

During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye

What is the name of the stage that a cell goes through just prior to mitosis?

Interphase, specifically Gap 2, or G2


What happens during metaphase in the cell division?

Metaphase is the phase of cell division where chromosomes line up on the equator of the cell just prior to splitting to the poles at anaphase. During mitosis identical chromosomes pair up on the equator, wheras during meiosis the homologous pairs line up together during meiosis 1 and then homologous chromatids line up together in meiosis 2.


What is DNA replication and what is its function?

DNA replication is the process in which the DNA is copied prior to mitosis. It's purpose is to prepare the cell for mitosis, which is the division of the nucleus into two identical daughter nuclei, usually followed by cytokinesis, the division of the cytoplasm.


During Mitosis the cell is performing its special job?

No, the cell performs its special job during inter phase. During mitosis, the membrane around the cell's nucleus dissolves and the chromatids of each chromosome are separated and pulled to each end of the cell. As the nuclear membrane re-forms around each set of chromosomes, the cytoplasm of the parent cell begins to divide to form two daughter cells.www.answers.com/topic/mitosis


Which general phase of meiosis resembles mitosis?

Metaphase of both mitosis and meosis resemble one another. Here, the chromosomes are condensed and aligned at the centre of the cell just before it divides. This state prior to division is refered to as 'the formation of the metaphasic plane'
