When chromosomes become visible at the beginning of cell division what does each chromosome consist of?
The consist of DNA and various HistonesIn eukaryotes,genetic information is passed on by chromosomes. Well before cell division, each chromosome is replicated(copied). When copying occurs, each chromosome consists of two identical ''sister''chromatids.
At the beginning of cell division DNA and the proteins associated with the DNA coil into a structure called an?
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
When does a chromosome consist of 2 identical chromatids?
A chromosome consists of 2 identical chromatids during the S phase of the cell cycle, after DNA replication has occurred. The two chromatids are known as sister chromatids and are held together by a structure called the centromere.
A structure having two chromatids held together at a centromere?
This structure is called a chromosome. Chromosomes contain the genetic material of a cell and are replicated before cell division to ensure that each daughter cell receives a complete set of chromosomes. The two chromatids are identical copies of the same DNA molecule.
Are sister chromatids?
Bacterial chromosomes
When the chromosomes make an exact copy of themselves what are they then called?
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
What are look-alike chromosomes that are identical in structure with another member of the pair?
Homologous chromosomes

How do the structure and location of a prokaryotic chromosomes differ from that of a eukaryotic chromosome?
because they do
What is the structure that holds each chromosome to its exact copy?
The structure that holds each chromosome to its exact copy is called a centromere. The centromere is a region of the chromosome that serves as the attachment point for the two sister chromatids, which are the identical copies of the chromosome formed during DNA replication. The centromere plays a crucial role in ensuring the accurate segregation of chromosomes during cell division.
Of what are chromosomes composed?
Chromosomes are composed of DNA, which carries genetic information, and proteins that help support and organize the DNA. Together, these components form the structure of a chromosome, which can be seen during cell division.
What is cytogenetics?
(used with a singular verb) the branch of biology linking the study of genetic inheritance with the study of cell structure, esp. for human chromosome analysis for the detection of inheritable diseases. The branch of biology that deals with heredity and the cellular components, particularly chromosomes, associated with heredity.

Can you use the Word Chromosomes in a sentence?
A chromosome is a structure within a cell that contains genetic information. Damage to a chromosome may lead to a mutation in the daughter cells.
At the beginning of cell division DNA and the proteins associated with the DNA coil into a structure called an?
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
Is a chromosome a allele?
No, a chromosome is a structure that contains genetic information, while an allele is a specific variant of a gene located on a chromosome. Chromosomes contain many alleles that determine an individual's traits and characteristics.
What is a chromosome squash?
A chromosome squash refers to a technique used in genetics and cytogenetics to visualize and analyze chromosomes by flattening them on a slide. This method helps researchers study the structure, number, and organization of chromosomes in cells.
When does a chromosome consist of 2 identical chromatids?
A chromosome consists of 2 identical chromatids during the S phase of the cell cycle, after DNA replication has occurred. The two chromatids are known as sister chromatids and are held together by a structure called the centromere.
