Is chromatin a chromosome consisting of two chromatids held together by a centromere?
Not really... chromatin refers to the interplay between the DNA and proteins (such as histones) which allow the chromosome (DNA) to have its distinctive shape and structure. It also refers to the winding of DNA - DNA on its own is the famous double helix, but in a chromosome it mostly exists as a wound up string of DNA surrounded by proteins which hold it together.
What else can I help you with?
Are chromosomes and chromatid the same thing?
No, chromosomes and chromatids are not the same. Chromosomes are long strands of DNA that contain genetic information, while chromatids are one of the two identical halves of a replicated chromosome held together by a centromere during cell division.
Are the two sister chromatids that are connected by a centromere identical to one another?
Two sister chromatids that are connected by a centromere are identical to one another. They are duplicate copies of a chromatin.
How are DNA centrimere chromosomes chromatid and chromatin are related?
Chromatid- one of two identical parts of the chromosome after "S" phaseCentromere- the point where the two chromatids crossChromosome- carries DNA in (and between) organisms.
Chromatids are held together by a?
They are held together, or conjoined, at their centromeres. These quite small regions of the chromosome pairs contain a specific set or 'mix' of nucleotides that are most Happy when being 'confined' in close-quarters. Chromatin is another matter.
What is the region of a chromosome holding the two double strands of replicated DNA together called?
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
What is sister chromatin?
Sister chromatids are two identical copies of a single replicated chromosome that are joined by a centromere. During cell division, sister chromatids are separated and move to opposite poles of the cell to ensure each daughter cell receives an exact copy of the genetic material.
What is a list of the 3 parts of a chromosome?
Telomere - The ends of the chromosome. Centromere - The primary constriction of the chromosome. Chromatid - A single molecule of DNA. The centromere also divides the chromosome into a short arm (p) and a long arm (q).
What is cetromere?
The centromere is a region of a chromosome that plays a critical role in cell division. It is responsible for ensuring proper segregation of chromosomes during mitosis and meiosis. The centromere serves as the attachment site for spindle fibers that help pull apart sister chromatids.
Are chromosomes and chromatid the same thing?
No, chromosomes and chromatids are not the same. Chromosomes are long strands of DNA that contain genetic information, while chromatids are one of the two identical halves of a replicated chromosome held together by a centromere during cell division.
When DNA has replicated the copied sister chromatin's remain attached to what structure?
After DNA replication, the copied sister chromatids remain attached at a region called the centromere. The centromere holds the sister chromatids together until they are separated during cell division. This attachment is crucial for proper chromosome segregation during mitosis and meiosis.
Are the two sister chromatids that are connected by a centromere identical to one another?
Two sister chromatids that are connected by a centromere are identical to one another. They are duplicate copies of a chromatin.

The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
When does the classic chromosome structure of DNA appear during mitosis?
The classic chromosome structure of DNA, characterized by tightly coiled and condensed chromatids, appears during prophase of mitosis. During this phase, chromatin fibers condense, making the chromosomes visible under a microscope. Each chromosome consists of two sister chromatids joined at the centromere. This organization is crucial for the accurate segregation of genetic material during cell division.
During which phase of the cell cycle do chromatids form?
When a single chromosome is replicated, two sister chromatids are produced. After cell division, each of the chromatids is a chromosome for the daughter cell.
What does the cemtromere do?
The centromere is a region on a chromosome that helps in the proper alignment and segregation of chromosomes during cell division. It serves as the attachment point for spindle fibers, which aid in moving the chromosomes to opposite ends of the dividing cell.
