Solved in 5 steps
- 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?Indicate which of the following items are associated with transcription or translation. This could be in prokaryotes or eukaryotes, or both. Group of answer choices: Translation OR Transcription Sigma binds to the promoter mRNA binds to the small ribosomal subunit Spliceosomes remove introns and splice together exons Nucleotides are added from the 5' to 3' end tRNA anticodon binds to the corresponding mRNA codon STOP codon results in terminationThe following is a DNA sequence of gene Z. The underlined sequence represents the promoter for gene Z and the underlined and italicized sequence encodes the gene Z ribosome binding (RBS) site. Transcription begins at and includes the T/A base pair at position 60 (bold)

- Use the numbers below to indicate the correct order of events (from left to right) during the process of translation initiation in bacteria. large ribosomal subunit binds to the complex. IF3 is released. The small ribosomal subunit associated with IF1, IF2, and IF3 binds to the Shine-Dalgarno sequence on the mRNA. tRNA charged with f-methionine binds to the AUG codon at the P site. IF1 and IF2 are released, leaving the A site available for the second charged-tRNA to bind the codon at the A site. 3 1 5 4 2 2 1 4 5 3 1 3 5 2 4 3 4 2 1 5 4 2 1 3 5Which statement is false: A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protienIn a written paragraph, describe the difference between prokaryotic and eukaryotic TRANSCRIPTION. In your response, include the following: - differences in what structures (DNA, RNA, proteins etc...) are involved - differences in timing and location - DO NOT include any details on what happens after transcription
- Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. It is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. What is the difference between Rho Dependent and Rho Independent termination in prokaryotes?Researchers are studying the mechanism of the antibiotic chloramphenicol. They know that it prevents the formation of peptide bonds during translation. A model of the translation process is shown in the diagram. Which of the following describes where in the model chloramphenicol acts to interfere with the production of proteins from DNA? during initiation during elongation during termination during protein releaseAn activated eukaryotic transcription factor looks for specific:
