BIOL 1201 : Biology Exam 3
Document Summary
Therefore, infants with the condition often have lighter skin, hair, and eyes than brothers or sisters without the disease. Central dogma: flow of information within a cell, the flow is largely in one direction. Protein: transcription and translation is cytoplasm events. 5" attgc would be transcribed as: 3" uaacg. What is this information used for: used to make proteins and polypeptides, tell us the sequence of amino acids to make proteins. How is this regulated: which set of genes are actually turned on or off. Do the differences in organization lead to functional differences: transcription and translation can occur simultaneously, no nucleus, easy for the cells to take up foreign dna (transformation) Gene regulation: why regulate, energetics, cells don"t want to make something they don"t need, control. Repressible operon (trp operon: repressor (protein) produced in a inactive form, binds with co-repressor, complex blocks transcription, rna binds to the promoter, turned off genes, can control by the co-repressor.
