What is the pattern of dark bands on photographic film that is made when DNA fragments are separated by gel electrophoresis and tagged?
The pattern of dark bands on photographic film in gel electrophoresis of DNA fragments is called a gel electrophoresis pattern. The dark bands are formed by DNA fragments of different sizes that have been tagged with a fluorescent or radioactive marker. The position of the bands indicates the size and quantity of the DNA fragments.
Why does extracted DNA need to be fragmented?
In preparation for the electrophoresis step in "DNA fingerprinting" the electrophoresis process cannot separate meaningfully massive molecules like whole chromosomes. By using restriction enzymes that break the chromosomes at known places DNA fragments of a wide variety of lengths that the electrophoresis process can separate meaningfully will allow a pattern to be generated that can identify different individuals.
What is protein marker and what is its use in electrophoresis?
A protein marker is a mixture of proteins of known sizes that is run alongside unknown samples in electrophoresis. It is used as a reference to help estimate the size of the unknown proteins based on their migration pattern in the gel. This allows researchers to determine the size of proteins in their samples and compare them to standards.
Do identical twins have identical retinal patterns?
Identical twins, while sharing the same genetic material, do not have identical retinal patterns. Each individual's retinal pattern is influenced by various factors, including environmental influences and random developmental variations, leading to unique characteristics. Consequently, even identical twins will have distinct retinal patterns that can be used for identification purposes.
How do you interpret electrophoresis results?
Electrophoresis results can be interpreted by observing the migration pattern of DNA, RNA, or proteins through a gel based on their size and charge. Different molecules will migrate at different speeds and distances, allowing for separation and analysis. The bands seen on the gel can be compared to molecular weight markers to determine the size of the molecules in the sample.
A pattern produced from fragments of the DNA of a specific person?
A DNA profile is a pattern produced from fragments of an individual's DNA that can be used for identification purposes. This profile is unique to each person, except identical twins, making it a powerful tool for forensic investigations and paternity testing. DNA profiles are created by analyzing specific genetic markers or regions of the DNA that vary between individuals.
What are the differences in band patterns observed in gel electrophoresis between homozygous and heterozygous individuals?
In gel electrophoresis, homozygous individuals show a single band pattern, indicating that they have two identical alleles for a particular gene. Heterozygous individuals, on the other hand, show two band patterns, indicating that they have two different alleles for the gene.
What is the value of the thickness of wire using He-Ne laser?
The value of the thickness of wire using a He-Ne laser can be determined by measuring the interference pattern produced when the laser light is reflected off the wire. By analyzing this interference pattern, the thickness of the wire can be calculated based on the wavelength of the laser light and the angles at which the interference occurs.
Following electrophoresis what is the resulting DNA pattern called?
The resulting DNA pattern following electrophoresis is called a gel electrophoresis banding pattern. This pattern shows the separation of DNA fragments based on size as they move through a gel matrix under an electric field. The smaller fragments travel faster and appear towards the bottom of the gel, while the larger fragments move slower and appear towards the top.

How can one effectively interpret electrophoresis results?
To effectively interpret electrophoresis results, one must analyze the pattern of bands on the gel, noting the size and intensity of each band. Comparing the results to a standard marker can help determine the size of the DNA fragments. Additionally, understanding the principles of electrophoresis and the specific experimental conditions used can aid in interpreting the results accurately.
Is all hair on a persons head identical?
No, not all hair on a person's head is identical. Hair can vary in texture, thickness, color, and curl pattern across different areas of the scalp. Factors such as genetics, health, and environmental influences can contribute to these variations. Additionally, hair may also differ based on its growth cycle, with some strands being in different phases of growth.
Did a roman soldiers leather sandals have iron nails on the soles?
Yes, they were called hobnails. An interesting fact about them is that the pattern of the nails in the Roman military boot was identical to the pattern of support used in present day training shoes.Yes, they were called hobnails.

What kind of pattern of bands on an electrophoresis gel would show from the DNA samples taken the Dolly?
They would be the same since Dolly is clone.
