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.
What event during interphase must occur for the cell to be capable of undergoing future divisions?
each chromosome must be duplicated
What is chromatid?
* the two exact copies of DNA that make up each chromosome.
What phase of meiosis does each replicated chromosome pair with its corresponding homologous chromosome?
Prophase 1 is the phase of meiosis ll when the homologous pairs combine. It is also when centrioles seperate, spindle fibers are formed, the nuclear envelope disappears, and the chromosomes become visible.
What can one half of a duplicated chromosome be referred as?
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.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid." ThoughtCo, Apr. 17, 2017.
How many sections is each human chromosome replicated?
23
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
How can you tell the difference between the original and replicated part of each chromosome?
In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
How does a pair of sister chromosome differ from a single unduplicated chromosome?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.

How many of each chromosome does a human have?
1 billion
Do human cells have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
What event during interphase must occur for the cell to be capable of undergoing future divisions?
each chromosome must be duplicated

How many chromosome 7 s are there in the human nucleus?
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
Do normal sperm or egg cells in a human have one copy of each chromosome?
Yes.
