What is an allele ladder and what is its function in DNA profiling?
An allele ladder is a mixture of DNA fragments of known sizes used as a reference in DNA profiling. It helps determine the size of unknown DNA fragments by comparing them to the ladder's known sizes. This allows for accurate identification of the alleles present in a sample for forensic or paternity testing purposes.
What is the function of allele ladder in DNA profiling?
An allele ladder is used as a reference for determining the sizes of DNA fragments in a sample during DNA profiling. It contains known fragments of DNA of varying sizes that are used to calibrate the gel electrophoresis results, allowing for accurate comparison and identification of the sizes of DNA fragments in the sample.
Which part of a blood cell is used for DNA profiling?
The DNA in the nucleus, although this would need to be a white blood cell as red blood cells have no nucleus, instead using the space to store oxygen.
In which type of case was the first DNA profiling done?
The first DNA profiling was conducted in a criminal case in 1986, when British scientist Sir Alec Jeffreys developed the technique to identify individuals based on their unique DNA patterns. This groundbreaking profiling was first applied in the investigation of the murders of two teenage girls, Lynda Mann and Dawn Ashworth, in Leicestershire, England. The DNA evidence helped to identify and convict the perpetrator, Colin Pitchfork, marking a significant advancement in forensic science.
Who discovered mitochondrial DNAprofiling?
Mitochondrial DNA profiling was developed by Dr. Alec Jeffreys in the 1980s. He is also known for pioneering DNA fingerprinting techniques.

What can't DNA profiling be used for?
DNA profiling is used by forensic experts to identify an individual. This technique is mostly used for parental testing and crime investigation.
How do scientist discover that gorillas similar to humans?
DNA profiling proved that we share 98% of our DNA with primates.
What is DNA profile?
DNA profiling is a technique employed by forensic scientists to assist in the identification of individuals on the basis of their respective DNA profiles.
Why is DNA fingerprinting unreliable?
DNA fingerprinting is not as reliable as regular DNA profiling. Statistics show that about one out every 800,000 people have the same DNA fingerprint.

The DNA in the nucleus, although this would need to be a white blood cell as red blood cells have no nucleus, instead using the space to store oxygen.
What emerging technology uses the principal component of chromosomes to identify suspects?

When DNA profiling is carried out the second DNA sample the one not collected at the crime scene is called the?
mitochondrial sample
