What is a short thick coil of DNA?
A chromosome is a short thick coil of DNA. A chromosome consists of two genetically identical halves called chromatids.
A duplicated chromosome consists of two?
Two sister-chromatids.Each chromatid consists of a molecule of DNA together with associated proteins. There are two DNA molecules (sister-chromatids) following the replication of DNA midway through the preceding interphase. The sister-chromatids are therefore genetically identical.chromatidschromatidsThe two identical joined chromosomes before cell division begins is called sister chromatids.
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.
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.
How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
During the cell cycle when would a chromosome consist of two identical sister chromatids?
During the interphase stage is whereby the chromosome consists of the two identical sister chromatids.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
each chromosome consists of two identical "sister" chromatids
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
What is difference between chromosome and chromatids?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere. They are known as sister chromatids. Once the paired sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.

Once a chromosome has been duplicated the two identical portions that are attched by their centromere are know as what?
chromatids.
What is the region of a chromosome where two sister chromatids attach?
The two identical chromosomes are conjoined at the centromere.
Is the animal cell the only one to have chromatids?
During mitosis, the chromatin condenses to form chromosomes. Each chromosome consists of two identical strands, or chromatids.
What are the two strands of a chromosome called?
The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.
