Summary Introduction
To determine:
The techniques used in DNA technology by the researchers to reveal the origin of meat.
Introduction:
DNA technology is the study and altering the genetic material of an organism to produce a new trait. The technology is useful in producing the pest resistance crops, highly nutritional food and so on. DNA technology consists of various techniques like Recombinant DNA technology, Gene therapy, DNA fingerprinting, DNA microarray technique and many more.

- Which of the following ingredients does not belong in a PCR reaction? (A) DNA polymerase B Primer Ligase D) DNTPS E) ddNTPs F) Endonucleasearrow_forwardThe idea behind PCR-based diagnostics is that a very small number of microbial genomes in a patient sample can be multiplied by PCR and more easily detected by the clinical team managing the patient’s care. Also, genetic-based diagnostics are very useful for viral infections because we don’t have biochemical tests, etc. to distinguish one virus from another (remember, viruses are metabolically inactive). However, a lot of work goes into the development of these tests. For instance, PCR requires primers that are complementary to the viral genome that is being copied. If primers are complementary to the target genome, what must scientists know to design primers that bind to the viral genome to be copied? (I mean this to be a general question; don’t look up the details of designing primers)arrow_forwardThere are four possible observations that suggest an error occurred in a PCR reaction: a) Sequence errors in the amplicon, b) the amplicon is the wrong size, c) there is no 6.

- Consider the following four DNA sequences taken from the a homologous gene from four different organisms. The bases are in groups of 10 for ease of interpretation.

For each pair of organisms determine the genetic distance between them. The genetic distance is simply the percentage difference between the two genes. Since each sequence is 50 base bases long, the genetic distance will be 2x the number of base differences. For example, if two sequences are identical except for one base, the genetic distance is 2%. b. List the genetic distances in the table below for each pair of organisms.
