A Palindrome Is

Question

A palindrome is
A) a DNA sequence that contains only one kind of base
B) a DNA sequence that contains only two kinds of bases
C) a sequence that reads the same from left to right or from right to left
D) none of the above

Accepted Answer

A palindrome is a sequence of characters that reads the same from left to right as it does from right to left. This term is commonly used in genetics to describe DNA sequences where the order of nucleotides is the same on both strands, such as "ATCGAT" on one strand and "TAGCTA" on the complementary strand. Choices A and B describe DNA sequences based on their base composition, but do not relate to the concept of palindromes. Choice D is too general and does not provide a specific definition for a palindrome.
