DNA, Transcription, & Translation Review

Which statement accurately compares DNA and RNA?

• DNA is a double strand, RNA is a single strand.

• DNA leaves the nucleus, RNA stays in the nucleus

• DNA uses the same nucleotides

• RNA is only involved in transcription, DNA is involved with both transcription and translation

Which base pairs with adenine in DNA?

• Cytosine

• Guanine

• Thymine

• Uracil

During transcription, DNA is transcribed into which molecule?

• Protein

• RNA

• Lipid

• Carbohydrate

What is the main function of mRNA in protein synthesis?

• To carry amino acids to the ribosome

• To form the structure of the ribosome

• To carry the genetic code from DNA to the ribosome

• To catalyze the formation of peptide bonds

What was Rosalind Franklin's contribution to the discovery of DNA structure?

• She determined that the amount of each nucleotide was the same in DNA

• She provided X-ray diffraction images of DNA, confirming a double helix

• She developed the base pairing rules

• She isolated DNA for the first time

What is the role of tRNA in translation?

• To transcribe DNA into RNA

• To carry amino acids to the ribosome

• To form the structure of the ribosome

• To replicate DNA
