D-low elevation and low relief
Answer: they damage proteins and DNA
<span>Oxidative stress and other cell processes induce the formation of highly reactive aldehydes that react directly with DNA of a microbial organism, forming aldehyde-derived DNA </span>adducts lead to proteins and DNA damage. DNA damage causes deregulation of cell homeostasis and thus contributes to the disease phenotype.

Answer:
c. YACs
Explanation:
YACs, the Yeast artificial chromosomes are the high capacity vectors designed to carry the eukaryotic genes and carry the insert of 200-2000 kb.
YACs carry origin of replication from yeast, selectable markers and sequences derived from telomeres and centromere to maintain the stability of the insert during cell division.
The insert size for plasmids, bacteriophage, PACs, and cosmids is about 0.1-10 kb, 5-25 kb, 100-300 kb, 35-45 kb respectively.
Answer:
To make sure that the experiment is accurate, the scientist must make carry out an appropriate observation, which would lead to the formation of good hypothesis. Good experimental method is an other criteria to look forward for the accurate experimental results. Methods are applied in collection of data and other things and in compiling results using statistical methods to carry out an accurate experiment.
