The sigma subunit of bacterial RNA polymerase ________________________. is required for the initiation of transcription binds to the RNA polymerase core enzyme must be released from the RNA polymerase for transcription to enter the elongation phase binds to the bacterial promoter sequence All of the other answers are correct.
Transcription of a typical gene encoding a polypeptide in eukaryotes involves all of the following EXCEPT: transcription of DNA corresponding to both introns and exons. transcription of the DNA corresponding to the gene of the polypeptide which may include UTRS (c) RNA synthesis by RNA polymerase II. the splicing together of a number of exons in the DNA prior to transcription.
TRUE FALSE EF-Ts factor regenerates EF-Tu/GDP from EF-Tu/GTP for the next round of elongation cycle in prokaryotic translation. The sigma o subunit of RNA polymerase is replaced by NusA to recognise the promoter region of a gene. The -10 and -35 sequences in E. coli DNA are referred to as untranslated region. In human, translation begins before transcription of an mRNA completes. The distal histidine stabilises the iron in heme group of a deoxyhaemoglobin. Receptor for epinephrine consists of seven transmembrane helices. Membrane receptors bind to hydrophobic signaling molecules. Amino acids, glucose and fatty acids are taken up by transporters into liver cells. Glycerol and fatty acids are synthesized from the intermediates of glycolysis. Synthesis of fatty acid occurs in cytoplasm. Triacylglycerol can be obtained from diet and also synthesized in liver cells. Ammonia and keto acid are formed in transamination.
Which of these statements is true about the elongation step of translation? The growing polypeptide chain is transferred from the P site RNA to the A site RNA OThe MRNA moves through the ribosome OThe new amino acid is transferred from the A site tRNA to the growing polypeptide chain in the P site The small ribosomal subunit detaches and reattaches every time a new amino acid is incorporated into the growing polypeptide
