This proportion is surprisingly low given the high abundance of these sequences in human genome (45%) and reveals that the amount of TEs is not related to the activity. Barbara McClintock in the early 1980s proposed that TEs could be activated by a genomic shock, and this might have an ...
The work is foundational for the “Weismann barrier” that puts a halt to (neo-)Lamarckian theories 1886: Theodor Escherich identifies a “bacterium coli commune” that resides in the human gut (E. coli) 1886: D.E. Salmon and Theobald Smith improve vaccination therapies by injecting whole ...
The world population and food production are disproportionally growing in a manner that would have never matched each other under the current agricultural practices. The emerging crisis is more evident with the subtle changes in climate and the running-off of natural genetic resources that could be ...
Tunisia is carrying out to this effect a set of projects, in the area of ecological tourism, namely the "Bni Mtir dam" in the delegation of Ain Draham which will be completed next year, as well as other projects in Zaghouan, Sidi Bouzid, Siliana and Kasserine. Radio and TV debate focu...
Laboratory testing of VWD outside of highly specialized centers is a challenge in itself, and the link between mild phenotypes and a VWF defect is not always straightforward. In addition, bleeding history relies on a subjective interpretation by the patients, their parents as well as the ...
Sumoylation is a process directed by an enzymatic cascade analogous to that involved in ubiquitination. However, in contrast to ubiquitination, sumoylation functions by regulating protein stability, nuclear-cytosolic transport, and transcription but not by protein degradation. In Arabidopsis, the central...
What aspects of the genetic code allow it to be replicated with very little errors? What is "a gene is expressed / not expressed"? What are the various ways a gene can change? Define each. What are genetic mutations? How can a transposon influence the expression of a gene?
Answer to: What is a change in the sequence of bases in a chromosome; a change to the base pair sequence of the genetic material of an organism? By...
