Transcription and Translation

What is the correct sequence of information flow in the Central Dogma of molecular biology?

• DNA -> Proteins -> RNA

• RNA -> DNA -> Proteins

• DNA -> RNA -> Proteins

• Proteins -> RNA -> DNA

In eukaryotic cells, where does the process of transcription primarily take place?

• Cytoplasm

• Ribosome

• Nucleus

• Mitochondria

What is the primary function of messenger RNA (mRNA) in protein synthesis?

• To carry amino acids to the ribosome

• To form the structural component of ribosomes

• To carry genetic information from DNA to the ribosome

• To catalyze the formation of peptide bonds

How many nucleotides in a messenger RNA (mRNA) sequence typically specify a single amino acid?

• One

• Two

• Three

• Four

What is the main role of transfer RNA (tRNA) during the process of protein synthesis?

• To carry the genetic code from the nucleus to the ribosome.

• To form the structural framework of the ribosome.

• To transport specific amino acids to the ribosome for polypeptide chain assembly.

• To unwind the DNA double helix during transcription.

During transcription, if a segment of the DNA template strand reads TAC, what will be the corresponding sequence on the messenger RNA (mRNA) molecule?

• ATG

• UAC

• AUG

• AUC

What amino acid is universally recognized as the starting point for protein synthesis, coded by the start codon?

• Threonine

• Glutamine

• Methionine

• Glutamic Acid
