- 27.1: Nucleotides and Nucleic Acids
- The structures of nucleotides and nucleic acids are explained.
- 27.2: DNA Base Pairs
- The double helix of DNA is held together by hydrogen bonding between the nitrogenous bases of the nucleotides.
- 27.3: DNA Replication
- New cells are continuously forming in the body through the process of cell division. For this to happen, the DNA in a dividing cell must be copied in a process known as replication.
- 27.4: Transcription of DNA
- The first step of DNA gene expression is the synthesis of messenger RNA, by a process called transcription.
- 27.5: Translation of RNA- Protein Biosynthesis
- Protein synthesis is accomplished by orderly interactions between mRNA and the other ribonucleic acids (transfer RNA [tRNA] and ribosomal RNA [rRNA]), the ribosome, and more than 100 enzymes.
- 27.6: DNA Sequencing
- The Sanger method for reading the sequence of DNA is discussed
- 27.7: Polymerase Chain Reactions
- Polymerase chain reactions can be used to synthesize DNA in a test tube.
