Molecular cell bio
True/False
1. The differences in the patterns of proteins produced indifferent specialized cell types are accurately reflected in thepatterns of expressed mRNAs.
2. Because the individual contacts are weak, the interactionsbetween regulatory proteins and DNA are among the weakest inbiology.
3. In terms of the way it interacts with DNA, thehelix–loop–helix motif is more closely related to the leucinezipper motif than it is to the helix-turn–helix motif.
4. Many transcription regulators in eukaryotes can act even whenthey are bound to DNA thousands of nucleotide pairs away from thepromoter they influence.
5. The close-packed arrangement of bacterial genes and geneticswitches may have developed from more extended forms of switches inresponse to the evolutionary pressure to maintain a smallgenome.
