DNA and Mutations Review

Which of the following is NOT a major difference between DNA and RNA?

• DNA is double stranded

• RNA cannot leave the nucleus and DNA can

• DNA contains thymine instead of uracil

• RNA is single stranded

The central dogma states that information flows from

• DNA to RNA to DNA

• DNA to polysaccharides to DNA

• RNA to DNA to polysaccharides

• DNA to RNA to proteins

Which of these describes the function of RNA polymerase?

• Amplifies the “message” by making multiple copies of an mRNA molecule after it has been transcribed from DNA

• Translates DNA into protein

• Transcribes DNA to mRNA

• Converts a protein sequence to mRNA

During DNA replication, a complementary strand of DNA is made for each original strand. If a portion of the original strand is CCTAGCT, then the new strand will be

• TTGCATG

• CCTAGCT

• AAGTATC

• GGATCGA

RNA differs from DNA in that RNA

• contains the nitrogen base thymine.

• contains the nitrogen base uracil.

• contains the sugar deoxyribose.

• contains the sugar ribose.

mRNA: CUC AAG UGC UUC

What is the DNA sequence this strand came from?

• CUC AAG UGC UUC

• CTC AAG TGC TTC

• GAG TTC ACG AAG

• GAG UUC ACG AAG
