Additional Problems
A particular triplet of bases in the coding sequence of DNA is AGT. What is the corresponding triplet in the complementary strand of mRNA? a. AGT b. UCA c. TCA d. GAC
Why is C. elegans a useful model organism for studying cell development?
DNA and RNA are both stands of nucleotides but RNA can carry out for more functions than DNA. How docs the structure of RNA differ from DNA? What additional activities/function can RNA do that DNA cannot?
Explain the difference between an intron and an exon.
What is the difference between horizontal gene transfer and vertical gene transfer? (You must define both in order to describe the diference.)
What is the difference between horizontal gene transfer and vertical gene transfer? (You must define both in order to describe the diference.)
List the three ways that bacteria can acquire new genetic information. For each one, name the essential mechanism through which the DNA is transferred.
 In the Central Dogma of DNA, producing RNA from DNA is called transcription and production of protein from RNA is called translation. Why were the words transcription and translation chosen to represent each of these steps?
What is an activator how does it act?What is a repressor how does it act?
How can mRNA processing in eukaryotes aid in regulation of gene expression?
How does the lactose regulate the inducible system for transcription of the structural and regulatory genes of the lac operon?
One of the major stabilizing forces of the double stranded DNA helix comes from hydrogen bonding. Where do you see this type of bonding in the DNA? Name one difference between DNA and RNA?
Compare Positive Regulation of gene expression with Negative Regulation of gene expression. Which includes and activator and which includes a repressor?
