5.If you want to analyze what happens to ALL the genes in a plant when it is subjected to a specific treatment (cold stress, for example), you should prepare total RNA from control and experimental plants and analyze gene expression levels by

Profiling expression patterns with DNA chips (microarrays)

Creating a genomic library

Conducting a polymerase chain reaction analysis

Creating transgenic plants

Ordering mutant seed stocks from seed repositories

6.When developing phylogenetic trees (cladograms), which of the following is should NOT be incorporated

Ancestral traits.

Derived traits.

DNA sequences.

Analogous traits.

Homologous traits
