In early mitosis, each chromosome consists of two identical sister chromatids joined at a region called the centromere. Before mitosis begins, during the S phase of interphase, DNA replication occurs, resulting in the formation of these sister chromatids. Thus, a single strand of a chromosome in this context refers to one of the sister chromatids, which will eventually be separated and distributed to the daughter cells during mitosis.
What else can I help you with?
Does mitosis copy the original strand?
Yes ,In mitosis , the original strands split into 2 parts with the help of enzymes forming "Y" shaped split .The exposed ends of the strand ,two new complementary strands are synthesised. So the duplicated strand of DNA contains 50% of the original strand and rest of the 50% is synthesised.
How many chromosomes do most prokaryotic cells have?
The number varies greatly between species.
Long strand found in the nucleus?
Chromosome
Another name of single strand wire?
Another name that can be used for a single-strand wire is thread or strand.
What is a chromosome unit?
A chromosome unit refers to a single chromosome, which is a long strand of DNA containing genetic information. In humans, a chromosome unit consists of two sister chromatids joined together at a centromere. Chromosomes are located within the nucleus of cells and play a crucial role in storing and transmitting genetic information during cell division.
Are chromosomes strands of DNA?
Each chromosome has a single strand of DNA.
What are some explanations of chromosome?
A single strand of bunched up DNA

Why does binary fission in bacteria differ from mitosis?
Binary fission in bacteria differs from mitosis because there is nuclear membrane involved. It also has simple DNA strand which has no spindle fibers to be formed.
How many chromosomes do most prokaryotic cells have?
The number varies greatly between species.
Long strand found in the nucleus?
Chromosome
Is thread an example of mitosis?
No, a thread is not an example of mitosis. Mitosis is a cellular process where a single cell divides into two identical daughter cells, while a thread is a thin strand of a material such as cotton, wool, or fiber.
A strand of replicated DNA formed during prophase is a?
A replicated DNA strand formed during prophase is called a sister chromatid. Sister chromatids are two identical copies of a single chromosome that are joined at the centromere. These sister chromatids will later separate during cell division.
What is the shorter segment of a chromosome?
Just a DNA strand
What do long strand of DNA in cells form?
a chromosome
How many DNA strands constitute a chromosome?
every and any DNA strand can constitue to a chromosome :)
What are the two halves of a double chromosome structure called?
The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.
