What ensures that each new eukaryotic cell receives a copy of each chromosome?
Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
Each chromosome usually contains multiple genes true or false?
Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
How does a duplicated chromosome differ from a chromatid?
Chromosomes are what make up your genetic material. During interphase when the chromosomes are duplicating, they remain attached to their duplicated with a centromere. When they are connected with their duplicate, each individual of this pair is called a chromatid. So a duplicated chromosome is made up of two chromatids which are identical to each other.
How many DNA molecules are present in a sperm cell?
A sperm cell contains 23 chromosomes, each made up of a single DNA molecule. Therefore, a sperm cell typically contains one copy of each chromosome, with a total of 23 DNA molecules.
A cell containing 92 chromatids at metaphase of mitosis at its completion how many chromosomes will be made?
At metaphase of mitosis, chromosomes are duplicated, so each chromatid will become a full chromosome. Therefore, with 92 chromatids, you will end up with 92 chromosomes after the completion of mitosis.
A copy of each chromosome is made?
interphase
A copy of each chromosome is made in which stage of mitosis?
One copy will be made totalling 2 of the same chromosome, one for each cell.
What ensures that each new eukaryotic cell receives a copy of each chromosome?
Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
When a chromosome has made a copy of itself each of the two strands is called this?
When a chromosome has made a copy of itself, each of the two strands is called a sister chromatid. Sister chromatids are identical copies formed during DNA replication and are joined at the centromere.
Copy of a chromosome made furing the cell cycle?
no
Each chromosome usually contains multiple genes true or false?
Can each chromosome usually contain multiple genes? yes each chromosome usually contains more than one gene.
Why do chromosomes double during prophase?
When a cell divides, each of the daughter cells should contain a copy of the entire genome. This is the reason why a copy of every chromosome has to be made so that one half can go into each daughter cell. If the parent call contained 23 chromosomes for example, during the synthesis phase of the cell cycle (of which prophase is a part), the total number of chromosomes will increase to 46 since each chromosome will be copied. When the cell divides to create two daughter cells, each daughter cell will contain 23 chromosomes.

What are four phases of the cell cycle and what happens in each phase?
G1 phase-the cell grows and begins replication process S phase- DNA process and replication begins. The cell has transferred all DNA to the cell being made. It makes an exact copy. G2 Phase-more growth takes place M phase (mitosis)-the chromatids line up and are ready to spilt into to daughter cells.
Which stage of the cleavage is the chromosome diploid?
G1 phase of Interphase in mitosis. It's after cytokinesis and before S phase in which the chromosome replicates and becomes 4n. In Meiosis it's before Prophase I and after Telophase I when cytokinesis occurs; then all through Meiosis II until final cell division in which 4 daughter cells that are haploid are made.
