Changes in a DNA sequence that affect genetic information are known as mutations.
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)
The gene theory declares that all organisms contain coded information in DNA which dictates the form and function of organisms.
<h3>What does the gene theory state?</h3>
Gene theory is one of the major principles of biology that explains the inheritance of traits coded by gene from parents to offspring.
This theory further explains that genes are located on chromosomes and consist of DNA, which stores them.
Therefore, the gene theory declares that all organisms contain coded information in DNA which dictates the form and function of organisms.
