16) If there are 20 centromeres in a cell at anaphase, how many chromosomes are there in each daughter cell following cytokinesis? A) 10. In a set of experiments, a student—faculty research team used labeled T nucleotides and introduced these into the culture of dividing human cells at specific...Centromeres are the region of a chromosome where the microtubules of the spindle attach during cell division. Centromeres are at the end of the chromatid where two Centromeres only appears when DNA replication occurs. The normal number of chromosomes in the cell is 10, and there are normally...Get more help from Chegg.Before separation sister chromatids remain attached at centromeres. After separation each chromatid becomes a daughter chromosome. The cell is still dividing and not separated in two daughter cells by cytokinesis. If there are 20 centromeres seen in anaphase...If there are 20 chromatids in a cell, how many centromeres are there? Negative Feedback of Hormones • Most hormones follow a negative feedback loop • Secretion of the hormone will cause a response which will reduce the stimulus which caused the secretion of the hormone.

How many centromeres are there if there are 20 chromatids in...

A centromere is a constricted region of a chromosome that separates it into a short arm (p) and a long arm (q). And these P and Q arms are a part of what we use when we do cytogenetics to say how many chromosomes are present in a cell and what chromosome number they are.If there are 20 chromatids in a cell, how many centromeres are there? Which term describes centromeres uncoupling, sister chromatids separating, and the two new chromosomes moving to opposite poles of the cell?The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad). During mitosis, spindle fibers attach to the centromere via the kinetochore. Centromeres were first thought to be genetic loci that direct the behavior of chromosomes.If there are 20 chromatids in a cell, how many centromeres are there? The lettered circle in the figure above shows a diploid nucleus with four chromosomes. There are two pairs of homologous chromosomes, one long and the other short.

If There Are 20 Chromatids In A Cell How Many Cent... | Chegg.com

There are 20 chromatids they should be in identical pairs of 2 (sister chromatids) as they have undergone replication. Therefore there would be 10 centromeres.Now that there are 20 chromatids they should be in identical pairs of 2 (sister chromatids) as they have undergone replication. Therefore there would be 10 centro-meres. Can you please give the brainliest?There are two pairs of homologous chromosomes, one long and the other short. One haploid set is symbolized as black and the other haploid set is gray. 16) If there are 20 centromeres in a cell at anaphase, how many chromosomes are there in each daughter cell following cytokinesis?Now that there are 20 chromatids they should be in identical pairs of 2 (sister chromatids) as they have undergone replication. Centromeres are the point at which two replicated sister chromatids are attached and only appear when DNA replication occurs.Most of the chromosomes in an eukaryotic cell are called autosomes which control all somatic Chromosomes are longest and thinnest during interphase. But on the onset of prophase there is a Due to lack of centromere, acentric chromosomes are not able to attach with spindle fibres and they...
