Answer:
50% G+C will have a higher Tm
Explanation:
The Temperature of Melting (Tm) refers to the temperature at which 50% of double-stranded DNA (dsDNA) is changed to single-standard DNA (ssDNA). In the double helix of DNA, Adenine bases always pair with Thymine bases through two hydrogen bonds, whereas Guanine bases always pair with Cytosine bases through three hydrogen bonds. In consequence, a DNA molecule containing a higher GC content is more stable than another DNA molecule containing a lower GC content. The Tm can be calculated as follows = 2 °C(A + T) + 4 °C(G + C) = °C Tm (this equation is useful for oligonucleotides of 14 to 20 base-length).
You have to first make some observations and then ask a question. Then you make a hypothesis (or guess) what the answer is - do the experiment to see if you're right!
Answer:
The correct answer is option-C
Explanation:
Anastosomes is a connection between the two interconnected tubular structures like in the loops of intestine or the blood vessels.
The anastomy between the blood vessels is known as the circulatory anastomosis. The connection is formed between the arteries and arteries or between veins and veins or between arteirs and veins.
The anastosome connections forms the bypass route for the flow of blood if one pathway of blood id blocked.
Thus, option-C is the correct answer.
