12/13 Practice Test

How are eukaryotic genes regulated?

• Master Control Genes
• suppressor proteins
• transcription factors
• regulatory proteins

Which of the following is NOT a STOP codon?

• UUA
• UAG
• UAA
• UGA

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

• DNA is two stranded and RNA is single stranded
• DNA contains deoxyribose and RNA contains ribose
• DNA is in eukaryotes and RNA is in prokaryotes
• DNA uses the bases ATCG and RNA uses AUCG

Why are DNA strands called 'complementary' strands?

• The strands are identical to each other
• The strands are able to be used to make the other strand
• The strands can divide themselves
• The strands can double the number of bases

In one way or another, all of the scientists in this section contributed to or concluded that

• Bacteria can be transformed
• Viruses use DNA to transport genetic information
• Pneumonia is deadly for mice
• DNA is the genetic material that makes up genes in all living things

What are the three roles of DNA?

• store genetic information, copy genetic information, and transmit genetic information to offspring
• store genetic information, transmit genetic information to offspring, and to create immunity from pneumonia
• copy genetic information, store genetic information, and destroy genetic information
• to create immunity from pneumonia, to copy genetic information, and to store genetic information

The three parts of DNA are

• sugar, lipid, protein
• fat, carbohydrate, phosphate
• sugar, phosphate, nitrogenous base
• nitrogenous base, sugar, carbohydrate

The four nitrogenous bases in DNA are

• adenine, thymine, uracil, guanine
• cytosine, guanine, adenosine, thorine
• thymine, adenine, cytosine, guanine
• guanine, cytoplasm, thymine, adenine

How is DNA replication in prokaryotes and eukaryotes different?

• Prokaryotes replicate in one direction while eukaryotes replicate starting at multiple locations
• Prokaryotes replicate in two directions while eukaryotes replicate in one direction
• Prokaryotes replicate at one location while eukaryotes replicate at multiple locations
• Prokaryotes replicate in multiple locations while eukaryotes replicate in one direction

How is DNA replication in prokaryotes similar to eukaryotes?

• They both replicate in both directions
• They both unzip, copy bases, and close up DNA when done
• They both make identical DNA strands when done
• All of the above
