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 does chrimatid mean?
A chromatid means one copy, or a daughter cell, of a duplicated chromosome, which is joined to another copy by a single centromere. Each contain the same DNA and chromosome protein as the original cell.
What is chromatid?
* the two exact copies of DNA that make up each chromosome.
Explain how the following terms are related to one another dna centromere chromosome chromatid?
DNA is bundled up into a chromossome with could be one or two chromatids depending on where the cell is in its cell cycle (two chromatids give the chromossome that X look). Both chromatids are bound together by a centromere.
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 a chromatid?
A chromatid is one half of a chromosome at a stage of the cell cycle when the chromosome contains two molecules of DNA.A chromatid is like a twin; you can only use the term when there are two of them!Before DNA replicates, each chromosome has only one molecule of DNA. After replication of the DNA, there are two DNA molecules in each chromosome. These become visible under a light microscope when the chromosomes condense during prophase of the next division.Each chromosome then looks like an X. The left side of the X contains one DNA molecule (together with proteins) and the right side contains the other. Each half of the chromosome is a chromatid. At anaphase of the division, the two chromatids are pulled apart. From then on they are no longer referred to as chromatids, but as daughter-chromosomes.
What is the difference between a chromatid and a centromere?
The centromere is the region of the chromosome that holds the two sister chromatids together during mitosis. The chromatid is one of the two strands of chromosomes that become visible during mitosis or meiosis.
What is the unraveled DNA called?
Chromatin, not to be confused with chromatid (one half of a chromosome).
Why does each chromosome have only one chromatid?
It is not two copies of DNA but double stranded DNA. Because our first cell (zygote) after the fertilization from male and female gametes (or cells that possess only one set of DNA or haploid) carry 1+1 DNA, it forms 2x as a result.
How are chromatid and a duplicated chromosome are related?
Chromosomes and chromatids are related in that one is the duplicate of another. A chromatid comes about when chromosomes are duplicated. It holds replicated DNA of every single chromosome that is joined.
Are chromosomes and chromatid the same thing?
Two chromatids held by the centromere is called a chromosome.
The two coiled up strands of DNA within a chromosome are called?
a centromere
