    Nucleic Acids Help

    Deoxyribonucleic Acid (DNA) Genes are made of the nucleic acid deoxyribonucleic acid (DNA). This molecule serves as the carrier of genetic information in all organisms other than some viruses. The double-helical structure of this long molecule is ...

    Protein Structure and Genetics Help

    Protein Structure Proteins function in nearly every aspect of cellular life and there can be thousands (or tens of thousands) of different proteins in a single cell. Enzymes, which catalyze most chemical reactions within a cell, are made of protein chains. Some ...

    Defining the Gene Help

    Defining the Gene Mendel's work suggested that a gene was a discrete "factor" that controlled a given phenotype (e.g., a gene for tall vs. short pea vine growth). Although the physical nature of the gene was not understood until the ...

    Protein Synthesis and Genetics Help

    Transcription There are two major steps in protein synthesis: transcription and translation. The first step is the transcription of DNA to an NA molecule. This process is carried out by the enzyme RNA polymerase. This enzyme attaches to the DNA at ...
