4 3 points Identify each of the following characteristics that are shared by DNA replication and transcription: Release of pyrophosphate each time the growing strand is lengthened by one nucleotide Contacts between the enzyme and the promoter sequence RNA polymerase Single-stranded binding proteins Formation of a temporary base-pairing association between DNA and RNA Nucleophilic attack by a free 3-OH group on the innermost phosphate group attached to the 5'-end of the incoming nucleic acid substrate 5 3 points Nucleotide synthesis is balanced as a result of the regulation of pyrimidine synthesis by: Pyrimidines only Ordered sequential binding Transcriptional controls Both purines and pyrimidines Feed forward activation 6 3 points A balance between the concentrations of AMP and GMP produced during purine synthesis is maintained because: GMP production requires ATP whereas AMP production requires GTP AMP inhibits GMP production and GMP inhibits AMP production Fumarate is released to the cytoplasm during the synthesis of AMP, but not GMP The concentration of IMP is regulated at the transcriptional level The energy required for both AMP and GMP production is provided by UTP
