To determine:
The reason why the complete and minimal nutrient replica plated.
Introduction:
Replica plating is a technique, in which secondary plates having a minimal media along with other ingredients such as antibiotics are inoculated by transferring the colonies from primary plate.
Explanation of Solution
The anabolic mutants are not able to use thechemicals present in the glucose minimal salt media to grow. In case, this media lacks microbes that grew on the complete media, then it can be concluded the microbes that are not able to grow are the mutants or the auxotrophs. So, the colonies that appear in only the complete nutrient plate can be isolated for the isolation of mutants.
So, for the isolation purpose both media are important.

- 1) A forensic scientist is required to collect blood samples from the crime scene and analyze it to help the investigators understand who participated to the murder. i) As a first step, the scientist needs to extract DNA. Indicate why red blood cells are not a good target for the analysis, and list at least two chemicals/compounds that are required to extract the DNA, explaining why they are used. ii) The sample has been collected in a small amount, so that (s)he decides to use PCR to analyze it. Describe why PCR is better suited to address small samples with respect to Southern blotting and how is selectivity addressed with this technique.arrow_forwardThe Evidence shows which suspect was at the crime scene? ( image of murder investigation) A) suspect A B) suspect B C) suspect C D) none were at the crime scene Which of the following choices most likely lists the sizes of the four DNA fragments in lane 6 ( second image) of this agarose gel stained with ethidium bromide? ( Note: the well that the DNA was loaded into is at the top of the gel image). A) 100 bp, 300 bp, 450 bp, 600 bp. B) 300 bp, 400 bp, 100 bp, 600 bp C) 600 bp, 450 bp, 300 bp, 100 bp D) 400 bp, 300 bp, 600 bp, 100 bp E) DNA fragment size can't be estimated using an agarose gel.arrow_forwardPlease help me identify the 3' and 5' ends of the DNA segment AGTCAT.
