What is the name of the structure that connects the sister chromatids?
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
Why is it pointless for sister chromatids to crossover?
Crossing-over occurs between non-sister chromatids, since (prior to crossing-over) sister chromatids are genetically identical (i.e. one is a duplication of the other). Therefore, if sister chromatids underwent a cross-over, no genetic variation would occur.
What are the sister chromatids in a chromosome attached by?
Sister chromatids in a chromosome are attached by a structure called the centromere. The centromere is a region where the two sister chromatids are held together until they separate during cell division.
Which molecules is critical for the proper separation of sister chromatids?
The molecule critical for the proper separation of sister chromatids is called cohesin. Cohesin is a protein complex that holds the sister chromatids together during cell division. It helps ensure that the sister chromatids are accurately and evenly separated into two daughter cells.
What is the next step after chromosome duplication?
is it two chromatids or spindles
When do sister chromatids separates?
Sister Chromatids separate during anaphase.
What is the name of the structure that connects the sister chromatids?
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
What chromatids are attached at the centromere?
Sister chromatids are the chromatids that are attached at the centromere. Sister chromatids are two identical copies of a chromosome produced during DNA replication, and they remain attached until they are separated during cell division.
Do sister chromatids have the same genes within them?
Yes, sister chromatids have the same genes within them.
Do sister chromatids separate during mitosis?
Yes, sister chromatids separate during mitosis.
What is a cell structure that joins two sister chromatids of a chromosomes?
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
Why do sister chromatids cross over?
Sister chromatids dont over cuz they dont look it up lmfao
Do sister chromatids have the same alleles within a chromosome?
Yes, sister chromatids have the same alleles within a chromosome.
Why is it pointless for sister chromatids to crossover?
Crossing-over occurs between non-sister chromatids, since (prior to crossing-over) sister chromatids are genetically identical (i.e. one is a duplication of the other). Therefore, if sister chromatids underwent a cross-over, no genetic variation would occur.
When a double helix DNA is replicated two complete helices are formed together these helices are called sister?
Sister chromatids - two copies of the same DNA joined at the centromere.
What is the difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.
What are the sister chromatids in a chromosome attached by?
Sister chromatids in a chromosome are attached by a structure called the centromere. The centromere is a region where the two sister chromatids are held together until they separate during cell division.
