What structure do copied sister chromatids remain attached?
centromere
What two paired cell structures are copied before mitosis begins?
Before mitosis begins, the chromosomes and other materials are copied. The pair of centrioles which are also copied. Each chromosome now consist of two chromatids.
During crossing-over what happens to portions of chromatids?
breaks off and attach to adjacent chromatids on the homologous chromosome
What is the difference between recombinant and parental chromatids and how do they arise?
Parental chromatids are chromatids that have a combination of alleles identical to the parents and Recombinant chromatids are chromatids that have a mix of alleles from both parents.
What does interphase make copies of?
There are three stages in interphase G1, S, and G2. G1 the cell grows. S the DNA is copied and sister chromatids appear. G2 the cells grows and specializes DNA.
What does interphase mean?
Interphase is chromes are copied (#doubles). Chromosomes appear asthread like coila (chromathin) at the start, but each chromosomes) change to (sister chromosomes) changeto sister chromatids atend of thisphase.
What condenses into an X shape before mitosis?
Chromatids condense into an X shape before mitosis. Chromatids are identical strands of chromosomes. After duplication there are 12 chromatids that are in 3 pair of homologous chromosomes.
In what stage of the cell cycle is a cells DNA copied?
Synthesis (S) Phase:"A Cell's DNA is copied during this phase. At the end of this phase, each chromosome consists of two chromatids attached at the centromere."(C) BIOLOGY Johnson Raven (Honors)
What is the connector for sister chromatids?
Centromere connects the sister Chromatids
What happens to the amount of chromosomes during cell division?
During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.
What chromatids are attached at the centromere?
Strictly speaking, chromatids aren't attached; they grow that way. They are, however, formed during Prophase of mitosis and Prophase I of meiosis. A: CENTROMERES
2. What are sister chromatids When do the separate?
In anaphase I the sister chromatids remain attached, while in anaphase II the sister chromatids separate.
