Bio30 - Unit 4 Review

The basic concept that, in nature, genetic information generally can flow only from DNA to RNA to PROTEIN.

• central dogma (of protein synthesis/molecular biology)
• nonsense mutation
• UUA
• It is the wrong order, and should be RNA -> DNA -> Protein

Which of the following is the correct order of the central dogma of molecular biology?

• a . RNA -> protein -> DNA
• b . RNA -> DNA -> protein
• c . protein -> RNA -> DNA
• d . DNA -> RNA -> protein

Who was the first to demonstrate the process of transformation with lab mice and virulent/non-virulent strains of bacteria?

• a. Frederick Griffith
• b . Alfred Hershey and Martha Chase
• c . James Watson and Francis Crick (and Rosalind Franklin)
• d . Oswald Avery, Colin MacLeod, and Maclyn McCarty

Who is attributed the discovery of DNA as a double helix shape?

• a. Frederick Griffith
• b . Alfred Hershey and Martha Chase
• c . James Watson and Francis Crick (and Rosalind Franklin now-a-days)
• d . Oswald Avery, Colin MacLeod, and Maclyn McCarty

Which enzyme synthesizes new stands of DNA?

• helicase
• DNA polymerase
• DNA photonase
• DNA lipase

Which RNA brings the genetic code from the nucleus to the cytoplasm?

• transfer RNA (tRNA)
• messenger RNA (mRNA)
• DNA
• ribosomal RNA (rRNA)

If the sequence within a gene is GGUGGGCCAGGGCCC, what is the amino acid sequence of the corresponding protein?

• a . Glycine, Glycine, Proline, Glycine, Proline
• b . Proline, Proline, Glycine, Glycine, Proline
• c . Proline, Proline, Glycine, Proline, Glycine
• d . Glycine, Glycine. Proline, Proline, Glycine

This adds a "tail" to the mRNA

• splicing
• editing
• polyadenylation

• termination

If the codon is CGA, what is the anticodon?

• TCC
• GCU
• GCT
• AGG

Which amino acids would this sequence of codons, AUGGUUUACCGAUGA, code for?

• Methionine, Valine, Tyrosine, Arginine, Stop
• Phenylalanine, Tyrosine, Arginine
• Methionine, Valine, Tyrosine, Arginine
• Methionine, Leucine, Tyrosine, Alanine, Stop
