Exam 3 Study Guide Protein Synthesis A K A Gene Expression Transcription Translation 1 Cells are made to look and function differently because genes are not always making proteins The genes can be turned on by inducers or turned off by suppressors hence this is why every cell does a different function In other words some genes in that cell are regulated to turn on or off Additionally the proteins that are made in each different cell determine the cell s phenotype 2 RNA is single stranded not double stranded RNA has a ribose sugar instead of a Deoxyribose sugar RNA has the base uracil instead of thymine 3 Transcription is a gene sequence is used as a template to make mRNA This happens in the nucleus 4 Translation is when the mRNA strand is used to make proteins This happens in the ribosome 5 Inducers are responsible for turning on genes Repressors are responsible for turning off genes 6 Inducers bind to and remove the repressors while repressors bind to the promoter of the gene on DNA to prevent transcription 7 The proteins are made in the ribosome so they must have been translated at the ribosome to carry out later functions to transcribe and translate other genes 8 SKIP 9 SKIP 10 1 makes one cell different from another 2 some genes are only supposed to turn on to make specific proteins during certain stages in life 3 Gene regulation helps cells adapt to their environment 11 Yes if the base that has been changed changes the codon for which determines what amino acid binds to the sequence This change in sequence can potentially change what protein is made by coding for a different amino acid 12 Alcohol dehydrogenase and Aldehyde dehydrogenase Alcohol dehydrogenase converts alcohol into acetaldehyde and aldehyde dehydrogenase converts acetaldehyde into acetate Acetaldehyde is most harmful because it is a toxin That is why there is a second enzyme to break it down into acetate 13 The two fault alleles are ADH1C and ALDH2 ADH1C is the faulty allele of Alcohol
