How do sister chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Difference between sister chromatids and homologous chromosomes?
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
Why do chromosomes have 2 sister chromatids?
they're identical because they are the product of replication.
Before cell division begins each chromosomes consists of two identical joined chromosomes called?
Before cell division begins, each chromosome consists of two identical joined chromatids called sister chromatids. Each sister chromatid contains an identical copy of the chromosome's DNA molecule.
When do chromosomal material replicate?
Chromosomal material replicates during mitosis. Chromosomes become sister chromatids, which ultimately break off to form identical chromosomes and two identical cells.
What substance can be see when the cell divide under light microscope?
DNA in the form of chromosomes and sister chromatids (which are identical replicated chromosomes).
What stage of the cell cycle do chromosomes make identical copies of themselves?
Chromosomes make identical copies of themselves during the S phase (synthesis phase) of the cell cycle. During this phase, DNA replication occurs, resulting in the duplication of each chromosome into two sister chromatids. These sister chromatids are then separated during mitosis, ensuring that each daughter cell receives an identical set of chromosomes.
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.
Why are chromosomes pairs of DNA?
When chromosomes are visible, they exist as replicated DNA, so each chromosome consists of two identical sister chromatids, which will be separated during mitosis to form two new identical daughter nuclei.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
How do differ chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Why are Chromosomes called Double Chromosomes?
After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosomes, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes.
