Higher levels of senescence were associated with increased SASP. One way to do this is to run an agarose gel and check it visually. DNA containing four genes is shown, with the transcribed region of each gene highlighted in dark blue. In order to increase the sequence coverage of inserts most platforms allow inserts to be sequenced from both ends. As mentioned previously, variation due to the sampling process makes an especially large contribution to the total variance among individuals for transcripts represented by few reads. What is your DNA telling you? The central dogma of biology states that genetic information is passed first from DNA, then to RNA and then used for protein production. These two steps, though seemingly simple, eliminate the cause of many failed experiments.
