Answer:
Initial extension ( elongation)
Explanation:
in PCR cycle , there is a third step called as extension (also called as elongation step) which is performed at 72 ° C. In this step taq polymerase will add nucleotides to the primers attached for the extension of template Strand.
I think the nurse is actively listening to the patient. It is a technique in communication that is often used in training, resolution of conflicts and counseling. It is a technique used by nurses in order to reflect on what a particular patients is saying to help them understood more on what is the patient is going through.
Answer:
radiometric dating methods
Explanation:
The oldest rock layer will be at the very bottom, and as time goes on, more layers will form making the top layer the youngest layer and the bottom layer the oldest. This method can determine the amount of radioactive decay of certain elements which can help them make a geologic time scale.
Solution:
Nitrogen is important because, it helps us grow crops, and it produces grass for animal. It comes from lightning and is named nitrogen fixation
By which free nitrogen (N2) is extracted from the atmosphere and converted (fixed) into nitrogen compounds which are plant nutrients (fertilizer). In nature, this process is carried out by certain bacteria (present in the root nodules of legumes such as beans and peas), blue-green algae, and the lightning flash.
Thus the Nitrogen form the atmosphere the biotic part to the ecosystem converted into the biotic part.
Answer:
The statement that is not true for antibody staining is it can provide information about gene expression.
Explanation:
Antibody staining is important aspect of applied immunology. Antibody staining is done to determine a specific protein in a given sample.Antibody staining is done by using fluorescent dyes and also by using specific enzyme such as horse reddish peroxidase,alkaline phosphatase.
Antibody staining can be visualized with either fluorescent or radioactive labels. Antibody staining can be performed by western blotting method.Multiple antibodies can be used to stain different proteins.Antibody staining requires the hybridization of the complementary base sequence of the antibody and also the target protein to which it binds.
