Question 36 Correct Mark 1.00 out of 1.00 " Flag question Use the following information to answer the next question. 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. Individual 1 Individual 2 Individual 3 Individual 4 Individual 5§ Individual 6 The DNA for Individuals 3 and 4 could NOT be a. mitochondrial DNA from two people who have the same paternal v grandmother (both their fathers had the same mother) b. nuclear DNA from identical twins c. mitochondrial DNA from two people who have the same maternal grandmother (both their mothers had the same mother) d. nuclear DNA isolated from a hair left at a crime scene and a buccal swab from a suspect who was present at the crime Your answer is correct. The DNA from samples 3 and 4 are identical. 1. Since mitochondrial DNA comes solely from the mother, two people with the same maternal grandmother, would have mothers who got their mitochondrial DNA from their mother and passed it to their daughters. People sharing the same maternal grandmother would have identical mitochondrial DNA. 2. Fathers get their mitochondrial DNA from their mothers but do not pass it
