What dye is used to stain the bands of DNA?
it depends on the animal
What is the pattern of dark bands on photographic film that is made when DNA fragments are separated by gel electrophoresis and tagged?
DNA fingerprint
When comparing the DNA fingerprints of a parent and child the parent's DNA fingerprint must have?
DNA bands that match those in the child's fingerprint and that aren't from the other parent.
What do the bands on chromosomes signify?
The bands on chromosomes are chunks of DNA that stain differently. Depending on the section of the chromosome, there may be hundreds of genes or very few genes in each band.
How do you avoid smearing of DNA bands in gel electrophoresis?
Make sure the voltage does not run over 200.
A pattern of bands made up of specific DNA fragments is a?
DNA fingerprint
The patterns of colored bands on a gel tells the exact sequence of bases in DNA?
Yes, the colored bands on a gel tell the exact sequence of bases in DNA.
What do the bands on a restriction map show?
DNA sequence.

How does the DDC perform paternity tests?
They perform paternity tests by DNA tests, which is a very effective way to do tests. DNA is unique to everyone. If trying to find the parents of a child, they will take DNA from the parents and the child and test them in a Eletrophoresis. From there, they will observe the bands, if the DNA bands of the child matches any or both of the parents, they it is confirmed who is the parent.
How can DNA fingerprinting establish paternity?
DNA fingerprinting can establish paternity by comparing the genetic markers, or patterns, between the child and the alleged father. By analyzing specific regions of DNA, scientists can determine if the child has inherited genetic material from the putative father. If there are enough matching genetic markers, it is considered highly likely that the tested man is the biological father.
What is the role of EtBr in electrophoresis?
Ethidium bromide interchalates with DNA. It doesn't affect electrophoresis, but it help visualise the DNA bands after electrophoresis. The EtBr that is bound to the DNA will fluoresce under ultraviolet light.
What is the tool used to show the structure of DNA?
Tiamat and 3D-DART are 3D editing tool used to show DNA structures. The DNA strands can also be viewed using highly developed microscopes.
What do the bands on chromosomes signify?
The bands on chromosomes are chunks of DNA that stain differently. Depending on the section of the chromosome, there may be hundreds of genes or very few genes in each band.
