Biology A 14.1 Understanding RNA and Its Functions

What does the acronym RNA stand for?

• Ribonucleic Acid

• Ribosomal Nucleic Acid

• Ribose Nucleic Acid

• Ribosome Nucleic Acid

Which type of RNA carries the genetic code from DNA to the ribosome?

• Ribosomal RNA

• Transfer RNA

• Messenger RNA

• Nuclear RNA

What is the main function of ribosomal RNA (rRNA)?

• To carry amino acids to the ribosome

• To form the core of the ribosome and catalyze protein synthesis

• To copy DNA into RNA

• To carry genetic information from the nucleus

Which type of RNA brings amino acids to the ribosome during protein synthesis?

• Messenger RNA

• Transfer RNA

• Ribosomal RNA

• Nuclear RNA

What is the process called in which a segment of DNA is copied into RNA?

• Translation

• Replication

• Transcription

• Transformation

Which enzyme is responsible for synthesizing RNA from a DNA template during transcription?

• DNA polymerase

• RNA polymerase

• Ligase

• Helicase

What is a promoter in the context of transcription?

• A region of DNA where transcription ends

• A region of DNA where RNA polymerase binds to start transcription

• A type of RNA molecule

• A protein that helps fold RNA

Which part of a gene is removed during RNA processing and does not code for proteins?

• Exon

• Intron

• Promoter

• Codon

What is an exon?

• A non-coding region of DNA

• A coding region of a gene that remains in mRNA after splicing

• A type of RNA polymerase

• A region where transcription starts

Which of the following best describes the role of RNA polymerase?

• It translates mRNA into protein

• It synthesizes RNA from a DNA template

• It splices introns from mRNA

• It carries amino acids to the ribosome
