✅️ half a step of a very important ladder;

✅️ helps to build double and single spirals; pairing with one or templates for another;

✅️ has two rings that are not equal;

Have you guessed?

 One of my LinkedIn connections was very, very close. It does relate to a nucleotide.

It's Adenine (A). One of four organic bases (chemical components) that makes up the DNA "ladder" - the four letter code in which its information is written. The other bases are Cytosine (C), Guanine(G), and Thymine (T).

Each of the four bases is connected with other two chemical components (a phosphate group and a sugar, deoxyribose) to form a nucleotide (yes, like Jennifer guessed)

Each "step" of that ladder is made of "two halves" - a pair of nucleotides (A-T or G-C).

Each step of the RNA " single spiral" is only made of one nucleotide A, G, C or U (uracyl substitutes thymine in RNA; and the sugar is ribose).

So both DNA and RNA are called nucleic acids.

Adenine is a pyrimidine, with its chemical structure forming two different "rings" (or actually an hexagon and a pentagon linked to each other).

Fun summary on the awesome attached sketchnote.

Why does this matter after all?

Because the order of the letters in the DNA (which is copied to RNA) contains the information for our bodies to produce specific proteins and work properly.

When that order is changed it may also alter the proteins which are being produced, and in some cases this may result in disease.
