I am working with RNA samples, and I'm trying to be very careful about RNAse contamination.
With the osmolarity of the average vertebrate being around 300mOsml, and salt water having an osmolarity of 1000mOsml
I'm experimenting with a consumer-grade ElectroEncephaloGram (EEG) sensor and have created the image below using the device. Because the sensor on the device does not use a suction cup, there are a
If a person contracts a virus, viral conjunctivitis for example, is it possible for the individual to become "reinfected" with the exact same strain of the virus once the person has it treated and t
Is it alright to use RGB light panels in a room instead of the usual lighting
I understand multiple origin bubbles; DNA polymerase only synthesizes DNA from 5' to 3' and all that. But what I don't understand is why it has to be in fragments. Yes, DNA is anti parallel, and so
Create a list of the sequence of events that take place from the conduction of an action potential in a motor neuron axon to the completion of a muscle fiber twitch contraction elicited by that acti
Almost all organs in the human body have a rather large threshold within which the organ or tissue is capable of repairing itself using materials supplied by the body, whether it's made from organic
Did all life arise from 1 cell and only happen ONCE? If so what is the evidence?Is primordial ooze a possibility?
Stress echocardiography means a pair of cardiac ultrasound imaging examinations, before and after exercise. I assume that coronary blood flow is increased after exercise.
An interesting tidbit floating around the internet these days is that Dr. Duncan MacDougall apparently weighed people shortly before and after death, and found an average of a 21 gram discrepancy, t
Which cell types are the largest? the smallest? what would be the advantage of a smaller cell? (fibroblast,Macrophage,keratinocytes, lymphocytes).
Slow worms are considered lizards as opposed to snakes, both are reptiles. Now I get that there are traits that distinguish them (eye lids, ears ...). But snake species themselves vary already quite
Calculate the maximum rate of translation by a ribosome in a bacterial cell, provided in units of amino acids per second, so that the ribosome doesn't overtake an RNA polymerase that is transcribing
Natural selection is a central tenet of evolution. However, most biologists seem determined to prevent the extinction of the species that have been selected against.
The Kidd blood group in primates is inherited as a single gene with two codominant alleles (Jka and Jkb). We would like to verify that this locus actually follows simple Mendelian inheritance with c
Polydactyly (the presence of extra fingers and/or toes) is due to the presence of a dominant allele "P". The students in Tucker dorm at NC State were surveyed for polydactyly. 117 students were foun
Are alcohol soluble in water, and to what extent?
Starting a new project on protein-protein interactions and SNP analysis tool development.
It has recently been brought to my attention that live laboratory mice with specific cancer strains can be readily purchased for medical research. For example, the Jackson Laboratory sells mice with
What can be seen on the screen when stress echocardiography (a pair of heart ultrasounds before and after exercise) suggests ischemia?
When a neurone fires, it sends an electrical signal that jumps down the axon via the nodes of Ranvier very rapidly. At a synaptic junction, chemical brownian diffusion signalling with receptor surfa
My take of this over having fully-complementary adapters (ADAPTER1 - - - - - ADAPTER1) is that:-Upon primer annealing, the primer in turn would bind to the start AND end of the DNA fragment, and thu
Why is carbon so prevalent in biological molecules such as lipids
