What are sister chromatids? What is a centromere?Mitosis:Mitosis is the nuclear division that occurs just prior to cell division (cytokinesis) to produce two genetically identical daughter cells. Mitosis is a multistep process that involves chromosome condensation, alignment of the chromosomes on the...
The process of distributing a copy of each chromosome to the daughter cell during mitosis is called chromosome segregation.Answer and Explanation: Sister chromatids are held together by the centromere, a region of DNA that associates with a large protein complex to f...
What is Chromosome Banding? What is a Centromere? What are Chromosomes? What is Meiosis? Discussion Comments By matthewc23 — On Sep 30, 2011 @Emilski - Yes and no about chiasma forming during mitosis. Technically, the sister chromatids are connected in the center, but after reading this...
A centromere is a chromosome region ensuring sister chromatids' attachment during cell division. The centromere's position can affect the shape of the chromosome during cell division. 11 Centrosome Centrosomes are involved in cell division, cell polarity, and intracellular transport. During mitosis, ...
The period during which euchromatin is genetically active is referred to as interphase, which is the segment of a cell's life cycle when it is not actively engaged in cell division, and is sometimes referred to as interkinesis. This is a phase that generally occurs midway between mitotic, or...
I must be homozygous recessive, since I have blue eyes. Bycardsfan27— On Jun 27, 2011 We get one of each chromosome from out parents, but how is that decided? Do we get a certain allele from our dad and another from our mother?
What is the exact location of Centromere. 01:54 State the exact location of the following Chordae tendinae 01:33 Give the exact location of the following : Thyroid gland 00:55 State the exact location of the following structures: Ciliary body 03:02 (b) Mention the exact location of the ...
Achromatidis one of two strands of a copied chromosome. Chromatids that are joined together at their centromeres are calledsister chromatids. These chromatids are genetically identical. Chromatids are formed in both the cellular division processes ofmitosisandmeiosis. ...
Acts as a constriction point on the chromosome. The centromere's location can vary between chromosomes, influencing their shape during division. 7 Centriole Replicates during the S phase of the cell cycle. The replication of centrioles is crucial for proper cell division. 5 Centromere Contains sp...
Aberrant chromosomes with two centromeres, resulting from the fusion of two chromosomes. Breakage–fusion–bridge A mechanism producing chromosomal instability, triggered by the fusion of deprotected telomeres, which leads to repeating cycles of chromosome breakage and fusion. Fragile telomeres Breaks or ...
