If you were to start reciting the order of the ATCGs in your DNA tomorrow morning, at a rate of 100 each minute, 57 years would pass before you reached the end…

Base Pairing

A = T & C = G

Drawing DNADrawing DNA

Complete the DNA

strand by drawing in the correct matching

nitrogen base, then

complete the side of phosphorus

and sugar.

Triplet

The code within DNA is based on a triplet system…

DNA codes in three letter words……

What is a gene?

A human chromosome has thousands of genesEach gene is a recipe for a protein!

Chromosomes

Genome

Collection of genetic

information within all

genes contained in

the DNA molecule(s)

in a cell.

If the genome was a book, it would be the equivalent of 800 dictionaries. It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome.
