Answer:
There are no options in this question but generally a sample of DNA can be increased;
By using Polymerase Chain Reaction (PCR) technique.
Explanation:
This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.
In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
Tissue typing is a screening process in which cell markers in a donated organ or tissue are identified so that they can be matched to a recipient with similar cell markers. This has become more important in recent years because of the number of organ transplants
Vascular plants are the ones that posses vascular tissue, sporophyte, and true roots, leaves, and stems.
Explanation:
The vascular plants are land plants. They form a very large group in the plant family, varying in size, shape, color etc. All of the plants in this group share some characteristics that define them as vascular plants, such as having true vascular tissue, sporophyte, and having true roots, leaves, and stems.
Another characteristic of the vascular plants is that they have lignified tissue which have the purpose of distributing the minerals and water throughout all of the plant. Plants that fall into this group are the flowering plants, conifers, ferns, clubmosses, and horsetails, and they are spread out on almost all of the plant when plant life is possible.
