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.
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 is DNA analysis used for other than DNA profiling?
Another thing is to look for genetic damage or change in chromosome number which can lead to birth defects.

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.
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.
What emerging technology uses the principal component of chromosomes to identify suspects?
DNA profiling
When DNA profiling is carried out the second DNA sample the one not collected at the crime scene is called the?
mitochondrial sample
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 is the annual salary for a forensic technician who does DNA profiling?
aproximately 20000-50000 dollars depending on experience
