Unit 1 will cover DNA structure, the replication of DNA, and the process of protein synthesis. There will be two tests in this unit to help break the information up.

DNA stands for deoxyribonucleic acid and it is our genetic material. It is made up of three components: deoxyribose sugar, phosphates, and the four nitrogenous bases of adenine, guanine, cytosine, and thymine. It is found in the nucleus of our cells and it is what codes for our genes. We begin Biology B by learning all about this important code. We will study its structure, how and why it replicates, and how it is used to undergo the process of protein synthesis within our cells.

(will need additional DNA pieces to complete lab)





Protein synthesis is the making of proteins. This is a two part process that can be broken down into transcription and translation. Transcription occurs in the nucleus and it is the process of making RNA from DNA. Translation then takes that RNA information and uses it to make the protein chain.
