GEMPUR CHAPTER 6: EXPRESSION OF BIOLOGICAL INFORMATION

Which do DNA and RNA have in common?

• Both are double stranded.
• Both contain ribose molecules.
• Both contain phosphate groups.
• Both contain uracil.

The backbone of polynucleotide is made up of

• amino acids and sugars

• nucleotide bases, including thymine

• nucleotide bases, including uracil

• sugar-phosphate molecules

What is the complimentary mRNA sequence to the DNA sequence

5' A-T-T-G-C-A 3'

• 3' T-A-A-C-G-T 5'

• 5' U-A-A-C-G-T 3'

• 3' U-A-A-C-G-U 5'

• 5' T-A-A-G-C-U 3'

Which defines a codon in DNA or mRNA?

• pair of nucleic acid and sugar
• pair of phosphate and sugar
• three-base code
• two-base code

The "central dogma" states that genetic information flows from 

• Protein-->mRNA-->DNA
• Protein-->DNA-->mRNA
• mRNA-->DNA-->Protein
• DNA-->mRNA-->Protein

Transcription takes place in the 

• cytoplasm
• ribosome
• mitochondrion
• nucleus

The anticodon of a particular tRNA molecule is 

• complementary to the corresponding mRNA codon.
• complementary to the corresponding triplet in rRNA.
• the part of tRNA that bonds with a specific amino acid.
• catalytic, making the tRNA a ribozyme.

The region on mRNA that non as non-coding region

• introns

• exons

• codons

• anticodons

Translation occurs:

• Outside of the Nucleus
• Inside of the Nucleus

Translation is crucial to the process of making proteins. Which statement best describes what takes place during translation? 

• A copy of chromosomal DNA is created 
• Information in mRNA is converted into a sequence of amino acids in a protein 
• A RNA copy of a DNA strand is made.
  
• Instructions from DNA in the nucleus are brought to the cytoplasm
