I was reading Matt Ridley's "Genome" book. I am trying to understand the Interlocus Contest Evolution in his X-Y chapter. I do not understand why the X and Y chromosome would want to kill each other
If a human body were somehow to be kept at a cold temperature (say 30C) for the entire life of the given individual. And somehow the brain could be fooled into thinking that this 30C feels nice and
This report describes some actual measurements in pollen transfer to neighboring fields from GM fields, though they all seem to have been one-off measurements at some unknown time after the GM plant
In the majority of human beings, the apex of the heart (left ventricle) points towards the left side of the body. Sometimes however (approx. 1/12000 births), a person is born with a condition known
A human's body temperature averages at around 98.6°FA dog's body temperature averages at around 101.5°F
Zebrafish are raised in fish tanks with one family per tank. The mutation spadetail is a recessive lethal. A stock tank for spadetail was made by crossing two carriers.
Explain why electron flow through Complex II is not associated with ATP synthesis even though electron flow through the other three complexes in the inner mitochondrial membrane is associated with ATP
Outline how natural killer cells destroy viruses and name a mechanism for how this works.
Briefly state the role of lymph node compared to the spleen.
Discuss the evidence that Hedgehog signalling is required to commit muscle precursors to a slow muscle fate in zebrafish.
In the early mouse embryo, the immediate environment of the somite comprises multiple tissues secreting different signalling molecules that pattern the somite.
Compare and contrast the effects of BMP and FGF signalling on the activity of the Smad1 protein.
In the context of ecological stability, define in your own words what the concepts of resistance and resilience mean.
In 1974, two hedgehogs were introduced into one of the islands in the Western Isles in Scotland, an area where hedgehogs do not naturally occur.
I've seen a large butterfly chase a different kind of butterfly around - it may, or may not have been territoriality.

As PCR has an unfortunate requirement of requiring a high temperature, I was curious about what options are out there to reduce the temperature during PCR denaturation or to stabilize the beads.
About half of the carbon dioxide released due to human activity has not been found in the atmosphere. Name a major sink other than the atmosphere, and briefly describe how long it is likely to remai
I read somewhere that eating a lot of salt will raise blood pressure, which will in turn damage brain tissue. This is because water molecules gather around salt ions, thus making it harder for the b

I have a list of candidate proteins as the result of my analysis. I am now trying to find various characteristics that they have in common. One of the things I would like to check is if my candidate
Usually the protocol for preparing electro competent E. coli cells calls for growing the cells at 37deg and 225rpms until they reach OD of 0.3.
