I think CT is an abbreviation for connective tissue. Some examples of its use in that fashion: http://en.wikipedia.org/wiki/Connective_tissue http://www.vetmed.vt.edu/education/curriculum/vm8054/Labs/Lab5/Lab5.htm http://www.pitt.edu/~sshostak/biosci1450/hislec03.html

This kind of thing is normally calculated using the $K_{a}/K_{s}$ ratio, the ratio of synonymous to non-synonymous substitutions. It is not enough to count mutations for coding sequences, you should also take into account whether or not that mutation will actually change the resulting product. There are various online tools that can help you do this, for ...

Question a The only possible genotype that brings a phenotype of 12 inches is: $AABBCC$. Similarly the only possible genotype that bring a phenotype of 6 inches is: $aabbcc$. In consequence the offsprings can only be: $AaBbCc$ which measure $2+1+2+1+2+1 = 9$ inches. Question b Now the question is: if we breed two $AaBbCc$ how many offsprings measure 11 ...

It does make a difference on polyacrylamide. A and C are faster while G and T are slower. Image from publication: The "standards" are AAA/TTT/GGG/CCC molecules.

Saccus simply means sac or bag and is is closed cavity. The lymph nodes develop from the structures, see this image: Superior cardinal vein (jugular vein) Jugular lymphatic sacs Right subclavian vein Axillary lymphatic sacs Left brachiocephalic vein Thoracic duct (bilateral) Lumbar lymphatic sacs Iliac lymphatic sacs The image is taken from this ...

Unfortunately, that isn't a very well-written problem, but I think I can help. If we assume simple Mendelian genetics, this would be a monohybrid cross, as you're only examining one trait (flower color). You have a pure-breeding white flower and a pure-breeding red flower. These make up the P (parental) generation. Their offspring will be the F1 (first ...

Practically speaking I have never seen a difference, but the agarose gels usually used in the lab do not have the highest resolution. There is one paper showing that the form (A- or B- form) and the GC-content play a role since DNA molecules of higher GC content are less flexible and therefore have more problems getting through the agarose matrix. ...

Lewis & Engelman (1983) Lipid bilayer thickness varies linearly with acyl chain length in fluid phosphatidylcholine vesicles. J. Mol. Biol. 166: 211 - 217. Table 1 and Figure 3 have the information that you need. For C14:0 the thickness of the hydrocarbon bilayer is given as 23 Å. Just in case this is homework, I'll leave you to convert that to ...

In the beta-Lactamase test, an inhibitor of beta-Lactamase is added to a sample of the culture medium. The inhibitor binds to the enzyme and changes its color, which is in direct correlation to the concentration of the beta-Lactamase. More b-lactamase means more inhibitor binding and this results in more color development leading to a higher absorption. So ...
