The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.

The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
What is the name for the fibers that become visible during metaphase?
The strands are called chromatids. Druing prophase, the chromosomes coil and shorten and the nuclear memebrane dissolves. Each chromosome is made up of a pair of strands called chromatids, which are connected by a spindle of fibers called a centromere.
Genes are located on structures called what?
The structures are called chromosomes.
What are strands of DNA called?
During Prophase I, DNA is exchanged between homologous chromosomes.Meiosis begins when a cell's chromosomes are duplicated by a round of DNA replication. The strand holding the DNA is the homologs and has an exact copy know as a sister chromatid.
When does a chromosome consist of 2 identical chromatids?
In eukaryotes, throughout the entire life of the Cell, also called the cell cycle. During Mitosis the chromosomes are separated.

What happens to the structures in the nucleus in each stage prophase plus?
In Mitosis, there are four stages involved in the separation of chromosomes. It produces two identical sets of chromosomes in two nuclei.1. Prophase: The double-stranded chromosomes condense, and the nuclear membrane around them degenerates.2. Metaphase: The chromosomes line up in the middle (equator) of the cell. The centrioles, which produce spindle microtubules, divide and move to either end of the cell. The spindle fibres form.3. Anaphase: Sister chromatids* are pulled apart by the spindle fibres.4. Telophase: The chromosomes are at either end of the cell, and new nuclear membranes start to form around them.*one of two identical copies/strands of DNA which make up a chromosome. They are generally 'X' shaped and joined at a point called the centromere.
What is the period during witch chromosomes duplicate is?
The period during which chromosomes duplicate is called the prophase.
What is the phase of mitosis when chromosomes become visibly shortened and thickened?
Prophase
What are strands of DNA called?
During Prophase I, DNA is exchanged between homologous chromosomes.Meiosis begins when a cell's chromosomes are duplicated by a round of DNA replication. The strand holding the DNA is the homologs and has an exact copy know as a sister chromatid.
What protein strands connecting the centrioles become visible during middle prophase and are almost complete by late prophase?
These strands are called spindle fibers. Each replicating chromosome lines up vertically on a spindle fiber during metaphase. During anaphase, the fibers pull the replicating chromosomes apart (leaving one chromosome to go to either end of the cell).
When does a chromosome consist of 2 identical chromatids?
In eukaryotes, throughout the entire life of the Cell, also called the cell cycle. During Mitosis the chromosomes are separated.
Genes are arranged on twisted strands called?
chromosomes
The strands of DNA in the nucleus are called?
chromatin
