Answer:
(a).concentrated lactic acid and that of NAD+.
(b).use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
Explanation:
To understand this question and be able to solve this question efficiently we have to understand the concept of "respiration''. But, the short and the most simple answer to the question above can be found in the first statement of the question.
The electron transport chain include the cycle that occurs during glycolysis, fermentation and the transformation of NAD+ to form NADH and vice versa.
In the research, the dependent variable is the concentrated lactic acid and that of NAD+.
In order to increase the validity of the experiment, the Researcher can make use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
The correct answer is that a bacteriophage lambda chromosome containing the human collagen gene, because Recombinant DNA is the name given to DNA molecules that have part of DNA derived from two or more sources, usually these sources are different species. Recombinant DNA technology is also known as molecular cloning or even gene cloning.
B. A bacteriophage lambda chromosome containing the human collagen gene
<h3>How is recombinant DNA produced?</h3>
Obtaining recombinant DNA is based on the molecular cloning technique. The process can be summarized as follows:
- The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
- The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
- The bacterial plasmid has the ability to insert a fragment of DNA external to its own genome.
<h3>What is DNA and what is it for?</h3>
DNA is the structure responsible for the transmission of all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. Thus, the main function of DNA is to transport information contained in its sequences, called genes.
