The " Central Dogma " of gene expression: (pages 302-303) What is the " central dogma " of gene expression? What is transcription? What is translation? What structures are needed to carry it out? What are the types of RNA and what is the role of each one? II. What is the "genetic code" and how does it work? (pages 304-305) Why is a genetic code needed? What is encoded by the "codons" of the code? How was it deduced that the code was in triplets of bases (the bases of nucleotides)? Which molecules carry the genetic code? What is meant by "reading frame" and "frameshift mutation"? How can a DNA molecule encode more than one protein? (how are "starts" and "stops" of proteins encoded?) To practice with how the code works, 1) draw out a hypothetical polypeptide with 5 amino acids and put together a base sequence that could code for this amino-acid sequence 2) draw out ...

There are two functions of a gene A. The passing on of information: heredity. Parent-child; fidelity of transmission. B. The governance of how cells and organisms develop, attain their form, and function in the adult. 1. This latter aspect of gene function is related to dictating the synthesis of proteins, a polymer composed of 20 different amino acid building blocks, strung into long polymers. DNA has the code for these proteins. 2. Illustration of proteins and bodily function: Sickle Cell Anemia. a.

    Excerpt: ... proteins and small RNAs that are needed for translation. In protein synthesis, the endoplasmic reticulum is the site of translation of membranebound and exported proteins. Retroviruses do not follow the " central dogma " of DNA RNA protein because they contain RNA that is used to make DNA. Mutations are heritable changes in the sequence of DNA bases. The type of mutation that stops translation of a protein is a nonsense mutation. The type of mutation that is an insertion or a deletion of a single base is a frame-shift mutation. The " central dogma " of molecular biology states that info flow in the cell is unidirectional, from DNA to RNA protein. Transcription is the process of synthesizing an RNA molecule using a DNA template. A transcription start signal is called a promoter. Initiation of transcription requires a temporary separation of the strands of the DNA template. The genetic code is best described as redundant but not ambiguous. The three codons in the genetic code that do not specify amino acids are ...
