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:
Reasons for failure to continue to use contraception include the following: for some, the risk of producing an unwanted pregnancy adds flavor to the sexual act; some women rationalize their sexual activity, and this usually leads to discontinuation of contraceptive use; failure to change the contraceptive when needs
Explanation:
Jupiter. The largest planet in our solar system by far is Jupiter which beats out all the other planets in both mass and volume. Jupiter's mass is more than 300 times that of Earth and its diameter at 140,000 km is about 11 times Earth's diameter
There are thousands of proteins in human bodies, each protein structure is determined by its amino and sequence. Different DNA coding eventually leads to a different protein being made, with a different structure.
