Question
CHAPTE e. Data mining is the act of gathering the raw data from research projects of such as sequencing into one central location d. Data mining u Data mining usually provides d. too much information, which only slows down the research project and is therefore e. None of the above and is not y useful. a. Which typ e of mutation is the most common? a. insertion of one or more bases b. depletion of one of more bases c. base substitutions d. inversion of DNA segments e duplications of DNA segments a. Which of the following statements about mutations is not true? a. Mutations occur in all organisms at the same r b. DNA polymerase never produce rate s mutations during replication because of the proofreading ability of this enzyme. . Mutations often occur at methylated cytosine residues. d. Mutations such as duplications or deletions occur due to repetitive sequences causing strand slippage. e. When comparing mutation rates to coding capacity, mutation rates are usually the same for most organisms, which suggests a mechanism to control the rate. of the following is often used to establish family trees for organ 10. Which one s because it is present in all organisms and does not accumulate muta- sms tions quickly? a. rRNA b. fibrinopeptides c. hemoglobin d. chloroplasts e. mitochondrial DNA 11. Which of the following statements about DNA microarrays is not correct? Fluorescently labeled mRNA from the organism hybridizes to the DNA on a. the glass slide b. DNA microarrays contain thousands of DNA segments on a support, such as a glass slide. c. Hybridization to a DNA microarray can only occur once d. The amount of fluorescence correlates with the amount of mRNA in the sample. e. The data obtained from DNA microarrays represents a global view of gene expression, even under particular growth conditions. 12. What is the term used to describe the process of synthesizing oligonucle otides directly on the glass slide? a. photosynthesis b. photolithography c. light-activated oligosynthesis d. on-chip oligosynthesis e. protected oligosynthesis Continued)Explanation / Answer
8. c. base substitution
Explanation: A single base substitution involves replacement of one base by another. It results in a changed codon which reads a different amino acid.
