Linkages

Linkage

(Science: genetics) tendency for two or more non-allelic genes to be inherited together, because they are located more or less closely on the same chromosome.

thus parental combinations of characters are found more frequently in offspring than nonparental. Linkage is measured by the percentage recombination between loci.

Re: How did endosymbionts coordinate replication?

... of the mitochondria can be limited by the availability of the nuclear-encoded gene products. It would be interesting if there are faster linkages, such as signaling cascades, the trigger mitochondrial replication checkpoints. I'm speculating; has anyone looked into the literature on this?

BN-PAGE of purified membrane associated protein

... Your protein is probably aggregating because its being run in a buffer that is making it negatively charged. It may be interacting with the cross linkages of the gel or even binding to itself.

Relationship between structure and function of glucoes

... I am do not understand why you said that "starch is a polymer of pure 1-4 β form". I understand that you mean the 1-4 glycosidic linkages are formed from the β form of glucose, but isn't that the α form? And thanks a lot for answering me!

Re: Relationship between structure and function of glucoes

... into either the α or β form. Galactose is pure 1-4 α-bound glucose while starch is a polymer of the pure 1-4 β form (though they may also have 1-6 linkages). Now I can look at your question again, Adz. The α and β forms of poly-D-glucose have different mechanical properties and adopt different ...

DNA 3' end & 5' end

Do you know about phosphodiester linkages? Each nucleotide is bound to the other (in the same chain) by these, and they are between the phosphate groups and terminal hydroxyl groups. The end starting with the phosphate is the 5' end and the ...
