Where in the cell cycle are chromosomes replicated?

The chromosomes are replicated during interphase.


During which phase of the cell cycle are the chromosomes replicated (copied)?

Chromosomes are replicated during the S phase of the cell cycle.


What is the difference between replicated chromosomes and unreplicated chromosomes in DNA?

Replicated chromosomes have undergone DNA replication, producing two identical sister chromatids joined by a centromere. Unreplicated chromosomes have not undergone DNA replication and consist of a single chromatid. Replicated chromosomes are found during the S phase of the cell cycle, while unreplicated chromosomes are present in the G1 phase.


The failure of replicated chromosomes to separate is called?

The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.


Genes and chromosomes are actually replicated during?

interphase


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.


In which organelle are chromosomes replicated?

Chromosomes are replicated in the nucleus of a cell. A nucleus is a membrane-enclosed organelle found in eukaryotic cells. It contains most of the cell's genetic material.


When do replicated chromosomes line up in the middle of the spindle?

Metaphase


How many replicated chromosomes would be on the metaphase plane in a human cell undergoing mitosis?

There are a total of 46 replicated chromosomes (plus 46 original), since metaphase precedes the actual division in anaphase, and each daughter cell receives 46 chromosomes in mitosis.


What are two equal parts of a replicated eukaryotic chromosomes?

sister chromatids


When do chromosomes (DNA) replicate?

mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process


The process where replicated homologous chromosomes are linked to form tetrads is called?
