AP Bio Transcription and Translation

What is the first step of gene expression?

• Translation

• Transcription

• Replication

• Mutation

Where does transcription occur in a eukaryotic cell?

• Nucleus

• Golgi apparatus

• Mitochondria

• Endoplasmic reticulum

What is the function of mRNA in the process of translation?

• mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

• mRNA regulates gene expression

• mRNA helps in the process of DNA replication

• mRNA is responsible for cell division

What is the role of tRNA in translation?

• tRNA is responsible for transcribing DNA into mRNA

• tRNA is involved in the replication of DNA

• tRNA helps in bringing the correct amino acid to the ribosome and matching it to the mRNA codon during protein synthesis.

• tRNA helps in breaking down proteins into amino acids

What is the genetic code and how is it read during translation?

• The genetic code is read during translation in groups of two nucleotides called codons

• The genetic code is read during translation in groups of three nucleotides called codons, with each codon corresponding to a specific amino acid or a stop signal.

• The genetic code is read during translation in groups of four nucleotides called codons

• The genetic code is read during transcription in groups of three nucleotides called codons

What are the three types of RNA involved in protein synthesis?

• mRNA, tRNA, rRNA

• pRNA, qRNA, sRNA

• xRNA, yRNA, zRNA

• cRNA, dRNA, eRNA

What is the difference between transcription and translation?

• Transcription creates DNA from RNA, while translation creates proteins from DNA.

• Transcription creates RNA from DNA, while translation creates proteins from RNA.

• Transcription creates RNA from proteins, while translation creates DNA from RNA.

• Transcription creates proteins from RNA, while translation creates DNA from RNA.

Explain the process of initiation in transcription and translation.

• Initiation in transcription and translation is the process of terminating the synthesis of RNA or protein

• The process of initiation in transcription and translation involves the binding of specific molecules to the DNA or mRNA to start the synthesis of RNA or protein, respectively.

• Initiation in transcription and translation involves the release of specific molecules from the DNA or mRNA

• Initiation in transcription and translation occurs in the middle of the synthesis of RNA or protein

What are the similarities and differences between prokaryotic and eukaryotic transcription and translation?

• Prokaryotic transcription and translation occur in the nucleus, while eukaryotic transcription and translation occur in the cytoplasm

• Prokaryotic transcription and translation are controlled by the same set of regulatory proteins as eukaryotic transcription and translation

• Prokaryotic transcription and translation involve the use of introns, while eukaryotic transcription and translation do not

• The similarities between prokaryotic and eukaryotic transcription and translation include the basic processes of RNA synthesis and protein synthesis, while the differences lie in the location and timing of these processes.

How do mutations in DNA affect the process of transcription and translation?

• Mutations in DNA only affect the process of transcription but not translation

• Mutations in DNA can result in the production of non-functional or altered proteins, affecting the normal functioning of the cell or organism.

• Mutations in DNA have no effect on the process of transcription and translation

• Mutations in DNA always result in the production of beneficial proteins
