A palindromic sequence is a nucleic acid sequence that reads the same no matter from the 5′ end of the sequence itself or from the 5′ end of its complementary strand. It has a potential to form a hairpin structure.

Writer’s text:

In DNA, when read on the 5¹ to 3¹ strand,  a palindromic sequence will read the same backwards as  forwards.11 For example, for the palindromic sequence  5¹AACGTT 3’, its complementary strand would be exactly the  same in reverse when read from 3’ to 5’. When not attached  to their complementary strands, palindromic sequences have  a tendency to fold back on themselves to form hairpin loops.

 Writer’s comment:

So because it was different from what I would expect from a palindrome in everyday English and I only found one paper and not very much in the textbook I didn’t know it was very widely used phrase to call something a palindrome in DNA. I thought it required a little bit more explanation.

The compound eyes, which are the visual organs of most adult insects, are much more complicated. The whole eye has an external transparent layer called the cornea divided up into facets, usually hexagonal in form, each of which is the outermost part of a visual structure called an ommatidium. In some dragonflies there are over 20,000 ommatidia in each eye, and most of the higher insects like flies and butterflies have several thousand. In worker ants there may be a dozen or less, and the eye hardly functions as a compound organ. (p.32)

On September 17, 1990, Lisa Olson, a sports reporter for The Boston Herald, charged five football players of the just-defeated New England Patriots with sexual harassment for making sexually suggestive and offensive remarks to her when she entered their locker room to conduct a post-game interview. The incident amounted to nothing short of “mind rape,” according to Olson.
