Transcription and Translation MakeUp-Quiz

The central dogma of molecular biology states that information flows in one direction

• nucleus to DNA to cytoplasm

• ribosomes to proteins to DNA

• genes to nuclei to ribosomes

• DNA to RNA to proteins

If you have the following DNA strand: GTAGTCA, what is the mRNA?

• UATUAGA

• ACGACTG

• CAUCAGU

• CATCAGT

The main function of tRNA is to

• carry a message that, when translated, forms proteins.

• form a portion of ribosomes, a cell’s protein factories

• string together complementary RNA and DNA strands.

• bring amino acids from the cytoplasm to the ribosomes.

Which of the following events occurs directly after RNA polymerase recognizes the transcription start site of a gene?

• The polymerase strings amino acids into a polypeptide.

• Free-floating nucleotides pair up with exposed DNA bases.

• A complementary RNA strand detaches itself from the DNA.

• The DNA strand begins to unwind, separating the two strands.

A primary difference between transcription and replication is that trancription

• copies the genetic information for only one gene.

• occurs within the nucleus of eukaryotic cells

• is catalyzed by large and complex enzymes

• proceeds according to careful cellular control.

What is the term for a three-nucleotide sequence that codes for an amino acid?

• base

• codon

• amine

• serine

Which phrase best describes translation?

• Converts mRNA into a polypeptide

• catalyzes bonds between amino acids

• produces RNA from DNA molecules

• recycles tRNA molecules for reuse

Which of the following is the site of translation?

• vacuole

• lysosome

• nucleus

• ribosomes

Which of the following is the site of TRANSLATION?

• vacuole

• lysosome

• nucleus

• ribosomes

Which lists the correct steps of protein synthesis?

• DNA Replication --> Transcription

• Transcription --> DNA Replication

• Transcription --> Translation

• Translation --> Transcription
