DNA , RNA , & Proteins

Structure of DNA

The structure of DNA is a double helix, with about 10 nucleotide pairs per helical turn.


DNA, or deoxyribonucleic acid, is like a blueprint of biological guidelines that a living organism must follow to exist and remain functional. RNA, or ribonucleic acid, helps carry out this blueprint's guidelines. Of the two, RNA is more versatile than DNA, capable of performing numerous, diverse tasks in an organism, but DNA is more stable and holds more complex information for longer periods of time.

Types Of RNA.

Messenger RNA

Transfer RNA

Ribosomal RNA

Transcription & Translation

Transcription is when we make RNA. It happens in the nucleus.

Translation is "reading" the RNA code to figure out what protein should be made, and it happens in the Ribosome.


  1. A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.
