Which type of RNA carries the code for a protein from DNA to the ribosomes?

• Nuclear RNA (nRNA)

• Ribosomal RNA (rRNA)

• Transfer RNA (tRNA)

• Messenger RNA (mRNA)

During transcription, which base does Adenine (A) pair with in RNA?

• Thymine (T)

• Cytosine (C)

• Uracil (U)

• Guanine (G)

What is the role of tRNA in protein synthesis?

• To transcribe DNA into RNA

• To catalyze the formation of peptide bonds

• To form the structure of ribosomes

• To carry amino acids to the ribosome

What is the first step of protein synthesis?

• Transcription

• Elongation

• Translation

• Replication

What is the function of ribosomal RNA (rRNA)?

• To carry genetic information

• To transport amino acids

• To catalyze the formation of peptide bonds

• To match mRNA codons with tRNA anticodons

What marks the end of the translation process?

• A start codon

• A stop codon

• A termination sequence

• A ribosome detachment

Where does translation occur within the cell?

• In the Golgi apparatus

• In the mitochondria

• In the cytoplasm

• In the nucleus

What is the role of the start codon in translation?

• To signal the end of protein synthesis

• To initiate the transcription process

• To signal the start of protein synthesis

• To bind tRNA to the ribosome
