Question 1 Which of the following statements about post-transcriptional processing is true? Possible Answers: A methylguanine cap is added to the 3' end of the mature mRNA Exons are spliced out of hnRNA and are not part of the mature mRNA Post-transcriptional hnRNA processing prevents RNA from degrading as it leaves the nucleus A poly-A tail is added to the 5' end of the mature mRNA Correct answer: Post-transcriptional hnRNA processing prevents RNA from degrading as it leaves the nucleus Que...

What is the Central Dogma of molecular biology? The central dogma of molecular biology explains that DNA encodes RNA through a process called transcription and RNA encodes protein through a process called translation. Describe how the information in DNA is used to produce specific proteins and can ultimately determine the characteristics of an individual organism. because of your DNA the certain RNA strand is coded from genes resulting in how your protein works. Describe the structure of DNA a...

BIO1A03 - TEST 2 QUESTIONS AND ANSWERS RATED A what components are required for translation initiation/elongation/release factors mRNA aminoacyl tRNA synthases tRNA ribosome (ribosomal RNA + ribosomal subunit) what is the role of tRNA - transfer amino acids from the cytoplasm to a growing polypeptide strand in a ribosome - each tRNA molecule has a different shape and therefore translates a specific mRNA codon into a specific amino acid what is the structure of tRNA - made up of a single RNA st...
