Summary Introduction
To write:
The DNA profile of two identical twin sisters and their biological parents.
Introduction:
DNA profile is a very commonly used technique to detect the paternity testing. The child gets some chromosomes of the mother and father. DNA profiling is also used in criminal investigations.

- DNA fingerprinting involves using restriction enzymes to cut DNA at a specific sequence, resulting in many fragments of different lengths. Gel electrophoresis then separates the fragments according to size. DNA fingerprints produced from four different individuals is shown below. The DNA for Individuals 3 and 4 could NOT be Select one: a. mitochondrial DNA from two people who have the same maternal grandmother (both their mothers had the same mother) b. mitochondrial DNA from two people who have the same paternal grandmother (both their fathers had the same mother) c. nuclear DNA from identical twins d. nuclear DNA isolated from a hair left at a crime scene and a buccal swab from a suspect who was present at the crimearrow_forwardGive a possible scenario on how DNA isolation and analysis can be used.arrow_forwardMake a punnett square to determine the genotypes and phenotypes that would result for each scenario.arrow_forward

Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?arrow_forward
