A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
What else can I help you with?
When does the chromosome duplicate itself in its life cycle?
will replicate itself during the synthesis phase within its life cycle
What is an individual stand of chromosome?
An individual strand of a chromosome is known as a chromatid. During the cell cycle, chromosomes replicate and consist of two identical chromatids joined together at a region called the centromere. Each chromatid contains a single DNA molecule that carries genetic information. In the context of cell division, chromatids are separated into daughter cells, ensuring that each new cell receives an accurate copy of the genetic material.
Which stange of a cell cycle do the chromosomes replicate?
Chromosomes replicate during the S phase (synthesis phase) of the cell cycle. During this stage, each chromosome is duplicated, resulting in two sister chromatids for each chromosome. This process ensures that when the cell divides, each daughter cell receives an identical set of chromosomes. The S phase is part of interphase, which precedes mitosis or meiosis.
When do chromosomes replicate?
Chromosomes replicate during the S phase of the cell cycle, which occurs before cell division. During replication, each chromosome is copied to produce two identical sister chromatids connected at the centromere. This process ensures that each daughter cell receives a complete set of genetic information.
How are viruses different from bactetia?
Viruses are not considered living organisms and require a host cell to replicate. They are much smaller than bacteria and consist of genetic material enclosed in a protein coat. Bacteria are single-celled organisms that can replicate independently and have their own cellular machinery.
When the chromosome makes a copy of itself it is said to what?
duplicate or replicate
Phase of cell cycle when the organelles and chromosome replicate?
Interphase
How is gene and DNA related?
chromosome consist of gene
When does the chromosome duplicate itself in its life cycle?
will replicate itself during the synthesis phase within its life cycle
Where does DNA replicate take place in the cell?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
Can a bacteraial plasmid replicate independently of the bacterial chromosome?
Yes, bacterial plasmids can replicate independently of the bacterial chromosome. Plasmids contain their own origin of replication, allowing them to replicate autonomously within the bacterial cell. This characteristic is advantageous for manipulating plasmids in genetic engineering experiments.
When chromosomes become visible at the beginning of cell division what dose each chromosome consist of?
sperm
What is an individual stand of chromosome?
An individual strand of a chromosome is known as a chromatid. During the cell cycle, chromosomes replicate and consist of two identical chromatids joined together at a region called the centromere. Each chromatid contains a single DNA molecule that carries genetic information. In the context of cell division, chromatids are separated into daughter cells, ensuring that each new cell receives an accurate copy of the genetic material.
What happens to the chromosome numbers during meiois?
During meiosis, the chromosome number doubles because the cells replicate their DNA and split into two cells in meiosis I and in meiosis II, they replicate DNA and split once again, to form four cells.
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.
Which stange of a cell cycle do the chromosomes replicate?
Chromosomes replicate during the S phase (synthesis phase) of the cell cycle. During this stage, each chromosome is duplicated, resulting in two sister chromatids for each chromosome. This process ensures that when the cell divides, each daughter cell receives an identical set of chromosomes. The S phase is part of interphase, which precedes mitosis or meiosis.
Mitosis is cell division in which the chromosome number is what?
Mitosis is cell division in which the chromosome number stays the same. Although at some points throughout the cell cycle, chromosomes may consist of two sister chromatids
