1. What is a consensus sequence? What are the components of RNA polymerase and what are their functions? 2. Describe the steps involved with transcription initiation.? Describe the steps involved with transcription elongation. 3. Describe the steps involved with transcription termination. A consensus sequence is a sequence of DNA,RNA, or protein that has aligned sequence.
. In bacterial genes, as soon as any partial mRNA transcriptis produced by the RNA polymerase system, the ribosome assembles on it and starts translating. Draw a diagram of this process, identifying 5′ and 3′ ends of mRNA,the COOH and NH2 ends of the protein, the RNA polymerase, and at least one ribosome. Why couldn’t this system work in eukaryotes?
Consider this list (below) of steps involved in transcription. These steps are out of order. TRANSCRIPTION: 1. mRNA travels through a nuclear pore and enters the cytoplasm 2. the mRNA polymerase attaches at the start of a specific gene 3. RNA polymerase reads the gene surface4. a transcription factor bonds to a promoter site5. DNA molecule is unwound 6. a complimentary mRNA is produced What is the correct order of this transcription?
1.Describe the journey of a protein, from its synthesis to its final destination 2. Explain the different stages of transcription and the role of the elements involved with the right terminology (template vs. non-transcribed strand, promoter, stop sequence, TATA box, general and specific transcription factors, RNA polymerase II, etc.); 3. Explain what the maturation (modifications) of pre-messenger RNA consists of and its role
20. in differential translation, a different transcript may be recovered depending on which TATA box is used true or false
9. Identify the TRUE statement about the process of transcription: * ORNA polymerase requires an RNA primer molecule before it can begin transcript ODNA is not needed for the process of transcription. RNA polymerase binds to a promoter region in the DNA to initiate transcription. O During the elongation phase, RNA transcripts are built from 3' to 5'. 10. Which is correct? * Translation occurs in the nucleus; transcription occurs in the cytoplasm O Transcription occurs in the nucleus; translation occurs in the cytoplasm Both transcription and translation take place in the cytoplasm Both transcription and translation occur in the nucleus

A scientist mutates elF-2 to eliminate its GTP hydrolysis capability. How would this mutated form of elF-2 alter translation? Initiation factors would not be able to bind to mRNA The large ribosomal subunit would not be able to interact with itiRNA transcripts tRNAi-Met would not scan mRNA transcripts for the start codon elF-2 would not be able to interact with the small ribosomal subunit.
