A geneticist working on peas has a single plant mono-hybrid Y/y (yellow) and, from a self of this plant, wants to produce a plant of genotype y/y to use as a tester.
I'm beginning to do some cell-binding assays and I would like for my proteins to not be endocytosed by my mammalian cells. Typical suggestions are for the cells to be kept on ice and that the bindin
I believe that there are predator/prey combinations where the prey can easily spot that the predator is not hungry and will not try to flee from it.
Personally, while I agree about the data density of the format, I can't help point out the large issues with the inability to rewrite and recopy the data efficiently and potential issues regarding t
Flies have a short lifespan, therefore evolution should technically happen over a shorter period of time (years).Flies die all the time from getting hit by cars on the motorway.
Our environment puts a great deal of pressure on every organism to adapt to its surroundings. Consider the differences between an animal that must survive in the arctic cold and one that lives in a
"hybrid" offers many competing definitions. But most seem to be centered on sexual-reproduction gene transfer.
My thought was, that the Isotype Control Antibody binds to all the antibody receptors, but with a "weak" binding. When the other antibody (e.g. CD73) tries to bind, it can make a stronger binding wi
In other words, if a salmon is artificially taken to lay eggs in a different, ("wrong") river, will its progeny return, when grown, to the river where they were born, or that where their mother was
I'm trying to assemble met genomic data that comes from termite guts. The sequences come from Solid and no paired, so the reads are extremely short (25bp).
There doesn't seem to be a lot of information available on research done on warts.
Mitochondria and plastids have their own DNA, their own membranes, and their reproduction is not tied to the reproductive cycle of the host cell. However, they are considered to be organelles rather
Other than CO? And Methane what other gases do humans produce or emit?For example, does skin decomposition, or aerobic respiration emit any special gases that people don't normally realize or know a
For drugs that are delivered either by intravenous, intramuscular, or sub-lingually (as in the other Biology.SE question), this first-pass effect is avoided, and the drug is introduced into the gene
I am interested in the odds with the usual level of care in an industrialized nation (and a mother that is not trying to abort the fetus).
It may be different for other people, but for me, anything above 32°C (90°F) is very uncomfortable, and my body is inclined to seek cooler temperatures. But I would think that at 32°C, t
There is a mutation where some organisms are slightly different and better traits are selected. However I cannot imagine how an organism will mutate to have lets say lungs at once and unless organis
You set up the following trihybrid F1 cross: AaBbCc x AaBbCc. Traits A and B demonstrate complete dominance, but trait C demonstrates incomplete dominance.
Pseudoephedrine increases the amount of endogenous norepinephrine, whereas phenylephrine works on ?1-adrenergic receptors directly.There are numerous cases where experts have spoken out about the e
In a testcross of Aa Bb CC Dd Ee, where the genes show independent assortment, what is the expected frequency of aa bb Cc dd ee progeny
I have recently been doing a lot of research into the interplay between the innate and adaptive immune systems in humans, and mammalian laboratory models. This has led to my reading some interesting
I am somewhat new to evolutionary biology, having studied it on my free time as a computer science student. There is one particular thing that has always bothered me for which I have not seen a good
I find it interesting that all life on earth use DNA. I've seen video on how helicase and ribosomes work together to copy DNA sequences (to RNA) with helicase then recreate them using ribosomes.
Why are insects so energy-efficient while flying? Is it because of their light weight and aerodynamics or due to very efficient biochemical transformations (food->energy)
I can imagine that the mechanism is different for each, but why does brain tissue and red blood cells use specifically and only glucose for energy metabolism
