Sister chromatids are attached to each other at an area called the?
The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.
When all the genes of a chromosome have duplicated but are still attached the strutures that are formed are called?
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.
Where is the region where the identical DNA molecules are most tightly attached to each other?
After DNA replication, when each chromosome exists as a pair of identical sister chromatids, the sister chromatids are tightly attached to each other at the centromere.
A protein disk that attaches two chromatids to each other in a chromosome is called a?
centromter
If an organism has 16 chromosomes in each of its egg cells what is the diploid number?
EACH CHROMOSOME WILL PRODUCE ONE DUPLICATE CROMATID FOR ITSELF AND THE TWO CHROMATIDS WILL GET ATTACHED TO EACH OTHER THROUGH THE CENTROMERE.SO AFTER DUPLICATOIN 16 SISTER CHROMATIDS WILL BE PRESENT BUT TOTALLY(16 ORIGINAL CHROMATIDS + 16 DUPLICATED CHROMATIDS) 32 CHROMATIDS WILL BE PRESENT
What is the small section of a chromosome where sister chromatids attach to each other?
Centromere
What is the area where a pair of chromatids is attached is the?
The Centromere, use the wiki article for further reading.
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
What structure is formed by two sister chromatids being held together by a centromere?
A bivalent.Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.
Each chromosome of a eukaryotic cell consists of a pair of identical structures called?
Chromosomes exist in somatic cells as nearly identical copies of each other called homologous chromosome. The formation of daughter cells that occurs during cytokinesis signals the end of cell division.
What prophase associated with nuclear energy?
This is nothing to do with nuclear energy: see WikipediaProphase is a stage of mitosis in which the chromatin condenses into a highly ordered structure called a chromosome (it is at this stage giemsa staining can be applied to elicit G-banding in chromosomes) in which the chromatin becomes visible. This process, called chromatin condensation, is mediated by the condensin complex. Since the genetic material has been duplicated in an earlier phase of the cell cycle, there are two identical copies of each chromosome in the cell. Identical chromosomes, called sister chromatids, are attached to each other at a DNA element present on every chromosome called the centromere.
What is the composition of a tetrad at the beginning of prophase you?
One pair of homologous chromosomes. One chromosome in a tetrad is paternally inherited, while the other is maternally inherited. Each chromosome consists of two chromatids.
