Hannah Fredrik, an undergraduate learning assistant, explains the differences between eukaryotic and prokaryotic transcription and translation. The tutorial covers the central dogma, transcription initiation, promoter differences, RNA polymerase binding, transcription termination, and post-transcriptional modifications. It also discusses the translation process, including ribosome recognition sequences and initiation factors. The video emphasizes understanding these concepts in detail and encourages reviewing lecture materials for deeper comprehension.

What is the central dogma of molecular biology?

• RNA to DNA to Protein

• DNA to RNA to Protein

• DNA to Protein to RNA

• Protein to RNA to DNA

Which regions are involved in prokaryotic promoter sequences?

• Downstream Promoter and TF2B

• Negative 35 and Negative 10

• Polyadenylation and Sigma

• TATA box and Initiator

What helps RNA polymerase bind to DNA in eukaryotes?

• Sigma factors

• Poly-A tail

• Shine-Dalgarno sequence

• Basal transcription factors

What is the termination process in eukaryotic transcription called?

• Splicing

• Rho-independent termination

• Polyadenylation

• Rho-dependent termination

Which of the following is a post-transcriptional modification in eukaryotes?

• Shine-Dalgarno sequence

• Sigma factor binding

• 5' cap addition

• Rho-dependent termination

What sequence do prokaryotes use to initiate translation?

• 5' cap

• Shine-Dalgarno sequence

• Poly-A tail

• TATA box

In eukaryotes, what must the ribosome do after attaching to the mRNA?

• Initiate splicing

• Attach to the 3' end

• Scan for the first AUG

• Bind to the Shine-Dalgarno sequence

Which factor is NOT involved in eukaryotic translation initiation?

• 5' cap

• Shine-Dalgarno sequence

• Initiation factors

• Ribosomal scanning

What is the main role of the Shine-Dalgarno sequence?

• To terminate transcription

• To position the ribosome for translation

• To add a 5' cap

• To splice introns

What is a key difference between prokaryotic and eukaryotic transcription?

• Prokaryotes use basal transcription factors

• Prokaryotes have post-transcriptional modifications

• Eukaryotes have post-transcriptional modifications

• Eukaryotes use sigma factors
