The seeds in bush bean pods are each the product of an independent fertilization event. Green seed color is dominant to white seed color in bush beans. If a heterozygous plant with green seeds self-
A pure-breeding fruit fly with the recessive mutation cut wing, caused by the homozygous cc genotype, is crossed to a pure-breeding fly with normal wings, genotype CC .
How do bacteria exchange their genetic material? Cell differentiation is a distinct phenomenon in eukaryotic animals. Name any four kinds of differentiated cells in your body.
I've seen a patient who had a Vasectomy (eye surgery) done on a single eye manifest massive swelling on both eyelids.That seems like having my left hand swell after punching a wall with my right one.
I've seen a few talks on the subject. From a gene cluster, there is some decent ability to determine which domains contribute to certain functional groups in the final metabolites. It sounds like th
In order to survive, prokaryotes such as bacteria need to produce energy from food such as glucose. In eukaryotic cells, respiration is performed by mitochondria, but prokaryotic cells do not have
When producing insulin, the gene for its production is inserted into the plasmid of a bacterium that is allowed to replicate freely.
We are running a gel on the products of a restriction digest to determine the size of an insert. We know the vector backbone size should be ~2.9kb; however, the standard appears to be running too qu
During inhalation, your alveoli expand; creating a pressure difference between the atmospheric pressure and our lung sacks and therefore air will flow into the respiratory airways.
If it were possible to live forever, would our brains grow infinitely with the number of memories that we store?
For some structural study I am looking for cyclodextrin strucutures (in 3D format such as pdb, mol2, etc) complexed with small molecule ligands, such as cholesterol and even smaller.
During DNA replication, RNA primase puts an RNA primer in the lagging strand.
I work with mice, and I want to see what happens to some specific proteins in the mouse brain after IL-1b injection (intracerebroventricular).I have a problem: when I measure the mRNA and protein le
What I'm wondering is what kinds of events would cause a different, more recent matrilineal ancestor to become the Mitochondrial Eve of all living humans?
I'd think protozoans can be oligocellular, but I haven't found any examples. I'm curious to know what is the minimum number of cells an organism can have other than a single cell.
Many publications suggest that often more complicated solutions are used. My first thought was to use a simple prepared detergent in PBS or saline for lysing the cells.
Most plants require carbon dioxide for their photosynthesis, which Mars has in overabundance.
If not, is there an alternative latin term to refer to studies of dead biological matter ? (e.g. in Connectomics where the tissue is biologically dead, and has been fixated and sectioned with a micr
If one were to take a DNA sample(or is it RNA?) of a caterpillar before it became a chrysalis, and attempt to match the sample against one taken after the chrysalis matured to a butterfly.
I am a science lover and want to buy a microscope to explore things around me. Like studying cell structures, microorganisms, blood and plants. It would be great if there is way to photograph slides
More specifically, shampoo. What are the mechanics of detecting a noxious chemical stimulus in terms of which receptors recognize what, how do they do it?
Sweaty palms seems to be a reaction to stress, anxiety, etc. For our forest-inhabiting primate ancestors sweaty palms could cause unwanted side-effects such as slipping off tree branches under stres
We know that we wash our hands because germs can get into our body through the nose, the mouth, the eyes, cuts, etc. But I doubt we can completely clean our hands of germs every time we wash them, d
Instead of using polymerase Vent exo (-), can I go with the usual Taq polymerase?
