Why is it important that new DNA be identical to the original?
The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed. This is Mitosis, hope this helps =]
In how many pairs the chromosomes in a karyotype match up?
In a karyotype, there are 23 pairs of chromosomes, for a total of 46 chromosomes. Each pair consists of one chromosome from the mother and one from the father.
How many chromosomes do birds have?
Nearly each species of bird has its own unique number of chromosomes. It can be very difficult to determine the exact number because many of these chromosomes are highly fragmented into multiple 'microchromosomes.' In short, the answer is: "It depends..."
Are chromosomes a part of every living cell?
No. Red Blood and some other cells do not have chromosomes.
What is the diagnostic tool that reveals missing or extra chromosomes and some structural changes in an individual's chromosomes?
A karyotype analysis is the diagnostic tool that reveals missing or extra chromosomes, as well as some structural changes in an individual's chromosomes. This test involves arranging and visualizing the chromosomes from a cell sample to identify abnormalities.
Why would it be much more difficult to construct a karyotype of unstained chromosomes?
It would be more difficult to construct a karyotype of unstained chromosomes because without stains, the chromosomes lack visible patterns or distinguishing features that are typically used to identify and organize them. Staining helps highlight the bands and patterns on the chromosomes, making it easier to match and pair them together for karyotyping purposes.
What are chromosomes that match from the sperm and egg?
homologues
Do any chromosomes match another in a sex cell?
Yes infact ther are many chromosomes that match each oher ina sex cell.
Do any any chromosomes match one another in a sex cell?
Yes infact ther are many chromosomes that match each oher ina sex cell.
What are the only pair of human chromosomes that do not always match?
69

What makes mutations happen?
A mutation in humans is caused by a misconnection of DNA chromosomes and cells. Not all mutations are genetics some are just a fluke with the DNA match up.
Why must the quality and quantity of DNA in cells remain the same from generation to generation?
If it changed too fast then it would be difficult for the chromosomes to match up and offspring could not be produced. The quality must be maintained or proteins and other systems will not work correctly.
Can a man and a dog successfully conceive?
Human and Dog chromosomes do not match up. the egg would be fertilized but then DIE after the first couple of cell divisions. That's what makes it appealing to some.
Why are individual chromosomes more difficult to see during interphase than during mitosis?
During interphase, individual chromosomes are more difficult to see because they are in a less condensed state and are spread out within the nucleus. In contrast, during mitosis, the chromosomes are highly condensed and tightly packed, making them more visible under a microscope.
Why do horses and donkeys remain isolated genetically?
This is due to the different chromosome numbers of the two species, horses have 64 chromosomes as the donkey only has 62 chromosomes. This will leave the offspring to have 63 chromosomes, allowing the pairs to not match correctly and creating successful embryos.
