Some $DNA$ molecules lack palindromic sequences.

Vedclass · Answer

(D) $DNA$ is a hydrophilic molecule due to the presence of the sugar-phosphate backbone,which contains polar groups. $DNA$ is negatively charged because of the phosphate groups in its backbone. Restriction enzymes are specific enzymes that recognize and cut $DNA$ at specific palindromic sequences. Therefore,the statement that some $DNA$ lacks palindromic sequences is technically incorrect in the context of restriction enzyme activity,as restriction enzymes require these specific sequences to function. However,in the context of general $DNA$ biology,the most scientifically inaccurate statement among the choices provided is that $DNA$ is hydrophobic (or implied by the options). Since $DNA$ is hydrophilic,option $A$ is a correct statement. Options $B$ and $C$ are also correct. Option $D$ is the incorrect statement because all $DNA$ molecules contain various sequences,and the concept of a 'palindromic sequence' is a specific requirement for restriction enzyme recognition,not an inherent property that $DNA$ 'lacks' in a general sense.

Which of the following statements regarding $DNA$ is incorrect?
