Biology EOC Macromolecule

Which statement correctly distinguishes DNA and RNA?

• DNA contains uracil, and RNA does not

• DNA contains nitrogenous bases and RNA does not

• RNA contains the sugar ribose and DNA does not

• RNA is arranged in a double helix and DNA is not

Transcription creates an mRNA molecule using DNA as as a template. Where does this process occur in cells of eukaryotes?

• in the nucleus

• in the cytoplasm

• in the ribosomes

• in the Golgi apparatus

DNA replication results in two separate DNA molecules. How are the DNA molecules at the end of the process related to the DNA molecule at the begining of the process?

• One strand of the original DNA molecule becomes one strand in each of the new DNA molecules ,While each other strand is made from cytoplasmic nucleotides

• Both strands of the original DNA molecule are stripped of their nitrogenous bases and each strand of the new DNA molecules is made using cytoplasmic bases

• Both strands of the original DNA molecule are broken down to their nucleotides and each strand of the new DNA molecules made from cytoplasmic nucleotides

• Both strands of the original DNA molecule are in one of the new DNA molecules and the other new DNA molecule is constructed from cytoplasmic nucleotides

At the cellular level ,lipids are the primary component of the cell membrane. Which statement would BEST support the argument that the structure of a lipid is related to this function?

• Lipids contain many hydrogen bonds

• Lipids are insoluble

• Lipids are constructed to store genetic information

• Lipids are composed of amino acids

A gene for human growth hormone (HGH) production is taken from human DNA and inserted in a bacterial plasmid. Which statement explains why bacteria are used as a host for organisms for creating recombinant DNA in this example?

• They replicate quickly, with each cell producing HGH

• They can be injected directly into patients to produce HGH

• They digest the gene and metabolize the nucleotides into HGH

• They provide the HGH production gene that can be inserted into a human cell
