thymine造句
1. Thymine or thymine nucleotide concentration was all disqulified.
2. Thymine: Organic compound of the pyrimidine family, often called a Base, consisting of a ring containing Both nitrogen and carbon atoms, and a methyl group.
3. Tritium labeled thymine deoxyriboside ( [ 3 H ] TdR ) uptake was measured to observe DNA synthesis.
4. Quantum chemical calculations of gossypol and thymine reveal that the net electronic charge distributions along the boldfaced line of their structural formula (Fig. 2) are just opposite in sign.
5. Resembles thymine, but easily interconverts to tautomeric form that pairs with guanine.
6. There are just four kinds: adenine, thymine, guanine and cytosine.
7. The other two, thymine and cytosine, are single ring structures called pyrimidines.
8. It is probably that the conjugated plane of gossypol is inserted into the base pair pleated sheet of the DNA double helical structure to associate with thymine through weak polar bond.
9. He uses zeroes and ones to represent the very first chemical building blocks of life (most likely compounds based on adenine, thymine, guanine, cytosine or uracil).
10. According to the AIM and NBO analysises, hydrogen bond between thymine and formaldehyde plays an important role in stabilizing the complex. Conformer (A) has the most stability in this work.
