Exam 10: The Structure and Function of Dna

The expressed (coding)regions of eukaryotic genes are called ________.

HIV (human immunodeficiency virus)must use its own ________ to reproduce.

The DNA codon GTA codes for an amino acid carried by a tRNA with the anticodon ________.

Prions are infectious molecules that can cause brain diseases in several animals. What type of molecule is a prion?

The RNA that is translated into a polypeptide is ________ RNA.

An mRNA is expressed that begins with the sequence AUGGGGCGAAUU. Using the genetic code below, determine what peptide will be translated from this mRNA.

After replication, ________.

DNA replication ________.

Scenario While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, the researcher isolated and cultured a single cell from this group and noticed that the progeny of this cell were not producing a certain protein, and that this affected their survival. -The mutation would be most harmful to the cells if it resulted in ________.

During translation, what is the CORRECT order of events that occur as an amino acid is added to a growing polypeptide chain?

All of the following are examples of potential emerging viruses except one. Choose the exception.

How many amino acids are common to all living systems?

What population is at the highest risk of being affected by Zika virus?

The region of DNA where RNA synthesis begins is the ________.

Scenario If you were asked to study the pattern of bacterial growth (increase in numbers over time)during an infection, you would find that numbers of bacteria increase exponentially up to a certain point. Assume that you have been asked to interpret the growth of bacteriophages. You infect the host bacteria and measure the increase of phages over a defined period of time. You plot the results and observe the graph shown here. -Once viruses are detected, the number of viruses increases rapidly. This is because ________.

Scientific research companies sell kits that allow researchers to produce proteins in test tubes via a process known as "in vitro translation." All of the following components are needed except one. Choose the exception.

In a DNA double helix, adenine pairs with ________ and guanine pairs with ________.

RNA vaccines have shown promise but have yet to be tested in humans. However, further evidence needs to be collected before human clinical trials can begin. Which would be the best experiment to perform to test the efficacy of an RNA vaccine against Zika virus in mice?

Scenario While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, the researcher isolated and cultured a single cell from this group and noticed that the progeny of this cell were not producing a certain protein, and that this affected their survival. -The mutation that resulted from the accident was probably ________.
