BIO FINAL EXAM 2024 WITH 100% ACCURATE SOLUTIONS

In a prokaryote, translation of an mRNA can start before transcription ends. This is not possible in eukaryotes. Why? a. nuclear ribosomes allow prokaryotes to do this work faster b. eukaryotes transcribe mRNA in the cytoplasm first, and then it is sent to the nucleus for transcription c. eukaryotes transcribe mRNA in the nucleus first, and then it is sent to the ER/cytoplasm for translation - ANSWER ☑☑c. eukaryotes transcribe mRNA in the nucleus first, and then it is sent to the ER/cytoplasm for translation *prokaryote is single celled* The following DNA strand 3'TTAACCGG5' is transcribed into what RNA strand? a. 5'AAUUGGCC3' b. 5'CCGGUUAA3' c. 5'CCGGTTAA3' d. 5'AATTGGCC3' - ANSWER ☑☑a. 5'AAUUGGCC3' The enzyme guanosines prevents 5' capping during transcription. What effect(s) would this have? a. the mRNA strand is degraded more quickly b. the exons are attached in the wrong order c. The mRNA cannot leave the nucleus d. the mRNA cannot bind to the ribosome e. Both c and d - ANSWER ☑☑e. both c and d
