Referring to the picture here, we can see there are rectangular drawings at the bottom that represent a train.
Upon being asked, “what is the difference between DNA and a gene?” we thought of answering it in this way.
If we assume DNA as a whole train, then the bogies/coaches of the train would resemble the genes.
DNA is a polymer of nucleotides that is made up of sugar (deoxyribose)+nitrogen bases+phosphate.
And genes are short segments of DNA that are code for proteins (not all DNA codes for proteins).
