Answer:
Explanation:
In the structure of Nucleic acids the nucleobases (nucleotide and bases) are arranged is a specific form.This form of arrangement is called Base stacking.It simply refers to the bond formed between the adjacent bases.
These nitrogenous bases of (A,T,C.G) pairing in DNA are in planes in geometry.The bases planes stack with one another.This form of arrangement give rooms for more Van der Waals interactions in the plane of the bases.Although the Van der Waals are weak interactions,the bond ensure that these bases are braided or twisted together to give maximum energy,to maintain stability of the bases,and therefore of DNA structure
Therefore in water and other aqueous solution the stability of structure of DNA is enhanced by the base stacking,(coiling or twisting)with maximum van der waals interaction among the bases, than the hydrogen bonds formed between bases.Generally there are more stacking among G-C,than A-T,thus the former pairing contribute more the structural stability than the latter (A-T)
Answer:
heat, density, boiling point
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
I believe the increase in blood pressure is limited by the Vasodialtion that causes arterial diameter to increase in the exercising skeletal muscle.
Vasodilation causes increase in blood flow due to decrease in vascular resistance. The resistance produced mainly in the arterioles which is known as the systemic vascular resistance or the peripheral vascular resistance. The cardiac output is the function of heart rate and stroke volume and must be always on check.<span />
