Root Explanation

Trinucleotide → It is formed from 'tri-' (meaning three) and 'nucleotide' (from 'nucleo-' meaning nucleus and 'tide' from 'nucleotides', which are the building blocks of nucleic acids). The word 'trinucleotide' refers to a sequence of three nucleotides, which are essential components of DNA and RNA.

Memory Tip

Think of 'tri-' meaning three, and 'nucleotide' as the building blocks of genetic material. This helps you remember that a trinucleotide is a sequence made up of three of these building blocks.
