Answer:
Pancreas
Explanation:
It is the main organ that regulates nutrients and sugar flow in the blood. That is why diabetes and other diseases most commonly occur in the pancreas.
The toxins are the substances which decreases the conc. of oxygen in wzater and increase toxicity
Answer:
miRNA ( micro RNA )
Explanation:
The small RNA molecule that interfere with gene expression are miRNA. The miRNA is micro RNA that are non-coding molecules of RNA. These small RNA regulate gene expression after transcription (post transcription).
The miRNA binds to 3' UTR region (untranslated region ) and halt the process of protein production and thereby silencing mRNA.
Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
