(Cannot be taken in conjunction with Body Structure and Function)
This unit involves the structure, function and replication of DNA. Nucleotide structure, double helix structure of DNA and the importance of base pairing and Hydrogen bonding is addressed. Comparisons are also made between the structure of RNA and DNA. The roles of nucleic acids in protein synthesis are also considered by looking at the process of m-RNA production and transcription, the role of ribosomes, m-RNA and t- RNA in translation.
