Real time PCR very accurately quantifies the amount of template DNA because it detects before any reagents become limiting Tor F Measurements of gene expression at the transcriptional level typically require making cDNA from mRNA Tor F. An important distinction between traditional Sanger (dideoxy) DNA sequencing and 2nd generation (NGS) DNA sequencing is that NGS gives longer DNA sequence "reads" Tor F.

Which of the following is not true regarding regulation of gene expression in eukaryotes? In eukaryotic cells, transcriptional activators often work by recruiting the transcriptional macinery to gene promoters DNA methylation is an example of an epigenetic mark that can be inherited Acetylation of histones can result in a more open chromatin structure to allow transcription to occur Different genes can be turned off or on between different organs or stages of development Transcription factor DNA sequences are bound by...

Tissue-specific microarray analysis facilitates the comparison
of gene expression in different tissues. In order to prepare a
sample for microarray analysis, messenger RNA (mRNA) is extracted
from a particular tissue, reverse transcribed to generate
complementary DNA (cDNA), and labeled with a fluorescent probe.
The microarray below shows comparison of gene expression in
stomach and intestinal tissues. The cDNA from stomach tissue was
labeled with red fluorescent probes, whereas the cDNA from the
intestinal tissue was labeled with green fluorescent probes....
