Explanation:
The genetically modified organisms are the organisms in which the genetic make up of the organism is altered. So that these organisms produce better yield and so as to improve their quality. The aim of genetic engineering in organisms is to develop or introduce a new trait in the organisms, which does not occur in the natural species. Thus the given statement is false as genetically modified organisms are reproducible.
<span>Radiotherapy. Radiotherapy is a form of cancer treatment which utilizes radiation in various forms such as x-rays, gamma rays, and electron beams or protons to kill or damage cancer cells so they cannot grow or multiply. This method of treatment is a localized treatment, which generally means that it does not cover the entire human body and only affects the area or part of the body where the radiation is targeted.</span>
Answer:
DNA markers are STRs or short tandem repeats, meaning that there are short sequences of DNA that are repeated. The more STR's that are seen through electrophoresis allows the test to be more discriminatory. This means that the more repeated DNA sequences there are the more it can be related to the individual and the more reliable it is. Therefore, the test with 10 markers would be more reliable DNA evidence against the defendant because there are more STR's in the sequence.
