Transcriptional regulation of the period gene through two distinct promoter elements mediates the working of the molecular clock and its entrainment by light.
I know that when RNA is transcribed from the original strand of DNA it contains introns and exons, and that the introns are spliced out of the strand to provide genetic diversity.
An individual with selective brain damage begins to show uncoordinated movements.
When sun rays shoot through my house from a window, sometimes if the lighting is correct, it will reveal a huge amount of floating particles and dust.
Why does the neuronal resting membrane potential approximate to the Nernst potential for K+ ?
Why are neurons said to have an ‘epithelial cell blueprint
In the first stage of the work, they have asked you to present them with alternative strategies for developing a growth factor releasing product.
In guinea pigs, white coat (w) is recessive to black coat (W) and wavy hair (v) is recessive to straight hair (V).A guinea pig that is black with straight hair but has an unknown genotype is crossed
This is the reason always cited for saltatory conduction and myelination, but my mental model of conduction tells me that the density of ion gates along the axon should not affect the speed of the A
Based on their family histories, a couple knows that they are each heterozygous for alkaptonuria (remember that condition where black urine is produced).The alkaptonuria phenotype is autosomal reces
Recent work published in Cell (2014) by Pagliuca et al, described a technique to generate many millions of pancreatic beta cells from human pluripotent cells in vitro.
Is the pain dependent on the compression of axons from mechanosensitive or nociceptive neurons?
Duchenne muscular dystrophy (DMD) is caused by mutations in the gene encoding dystrophin that lead to severe muscle weakening.
For instance, let's say a worker's base takes fire while he sleeps, and he has to run to the emergency building 200 meters away without any respiratory equipment, pressure suit, UV protections or an
How do near sightedness, farsightedness, and normal sightedness work?
Osteoarthritis is characterised by defects in joint tissue where both the outer cartilage and the underlying bone are damaged.
I have been trying to wrap my head around the concept of epistasis for a couple of days now, and I think I understand it, at least at a basic level, but I still don't understand some of the ways tha
Some recombinant proteins like human DNaseI and Factor VIII can only currently be made in pharmacologically active forms using mammalian cell culture.
Discuss how transgenic plant technology can be used to generate new crop varieties that would not be possible via conventional plant breeding.
Describe how the crelox system can be used to remove antibiotic resistance genes from transgenic plants.
How would you ensure that the protein was produced in milk and not other tissues
It is necessary to have extra source of CO2 i.e. from a nuclear reactor or factory chimney to produce bio-fuel by microalgae or is it able to do it with the normal CO2 density in the atmosphere?
I'm very interested in the "systems biology" field and I'm searching good (innovative) and recent (max 3-4 years old) articles about this subject, but unfortunately I've found my research more diffi
You are given a test tube with 1 ml of a recombinant protein that your colleague has just purified in the lab using affinity purification. How would you attempt to determine the concentration and pu
