In simple words, biology is the study of living organisms, including their genetic makeup, characteristics, physiology, and function. Biology is then further divided into branches that allow for a more in depth study of each branch. How many branches do we have in biology? In biology, there...
Moreover, cellular structures called cell organelles are suspended in the cytoplasm. What is a Cell? A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first...
not all cells build the same proteins. One reason for this is that molecules called "transcription factors" latch onto DNA to control which genes get switched on and off, and therefore, which proteins get made when, where and in what quantities in each cell,Live Science previously reported. ...

thetranscription rates are presumed to be similar, at any given time, theconcentration of various crRNAs in the cell would be multiple times higher thanthat of the enzyme. It has been experimentally shown that with sufficientconcentration of a new crRNA molecule, it is able to displace the ...
Although each one of your 37.2 trillion cells carries a copy of your DNA, not all cells build the same proteins. One reason for this is that molecules called "transcription factors" latch onto DNA to control which genes get switched on and off, and therefore, which proteins get made when,...
ENCODE (the ENCyclopedia Of DNA Elements) is a public research consortium that is trying to identify all of the functional elements in the human genome. And modENCODE is doing the same thing for model organisms.One of the surprising things that ENCODE has revealed is that transcription is not...
What goes up does not always come down: patterns of distress, physical and psychosocial morbidity in people with cancer over a one year period BackgroundAs the concept of distress as the 6th vital sign gains strength in cancer care, research on the experience of patients is critical. This ...
is active at the level of transcription, post-transcriptional, post translational cellular activity, and cellular signaling in several immune cell types, includingneutrophils,B cells,T cells,natural killer cells,macrophages, andlymphoidormyeloidcancer cells. Of interest, O-GlcNAcylation has a role in ...
Thepromoter, a DNA sequence that liesupstreamof the RNA coding region, serves as an indicator of where and in which direction transcription should proceed. The promoter is not actually transcribed; its role is purely regulatory. While promoters vary tremendously among eukaryotes, there are some comm...
