Biochemist Erwin Chargaff was the first to note that, in DNA, [A] = [T] and [G]= [C], equalities now called Chargaff’s rule. Using this rule, determine the percentages of all the bases in DNA that is 20% thymine.
I'm having difficulty with some homework, 6. a. The double helical structure of DNA is intrinsically unstable and easily dissociates to form two separate strands. Why? How does this affect the two key biological functions of chromosomal DNA? What would happen if the DNA helices were too stable? b. How can one measure the stability of a particular duplex DNA? Which molecular properties affect the stability?
3,Compare the free energy, ∆G, of A-T binding and A-C binding, which one is more negative? Does this makes sense in terms of the structure of DNA? Group of answer choices A, ∆G of the A-T binding is more negative than that of the A-C binding, which is consistent with the fact that A-C binding is not favored in DNA helix. B, ∆G of the A-T binding is more negative than that of the A-C binding, which is consistent with the fact that A-C binding is favored in DNA helix. C, ∆G of the A-C binding is more negative than that of the A-T binding, which is consistent with the fact that A-C binding is not favored in DNA helix. D, ∆G of the A-C binding is more negative than that of the A-T binding, which is consistent with the fact that A-C binding is favored over A-T binding in DNA helix.

DNA has pKa ≈ 1.0. At normal pH what would the charge be for a double helix that is chain 50 angstroms long?
Tick the correct statements: Remember: Tautomers are structural isomers that differ from each other based on the position of the proton(s) and their double bonds. ( ) The nitrogenous bases of nucleic acids, which contain heterocyclic and analogous nuclei, can adopt different tautomeric forms involving multiple H+ that are exchangeable depending on the medium. In DNA, spontaneous formation of smaller tautomers appears to contribute to mutagenic errors during DNA replication, while in RNA, they seem to be related to increased structural and functional diversity of enzymes and RNA aptamers (research this and confirm if it is false or real) ( ) in relation to the figure, anomer 1 has beta stereochemistry with respect to the C anomeric of the pentose, and is making an N-glycosidic bond ( ) in relation to the figure, anomer 1 has alpha stereochemistry with respect to the C anomeric of the pentose, and is making an N-glycosidic bond ( ) In general, in naturally occurring nucleosides,…
1a) The phosphate groups in the sugar-phosphate backbone of each strand of a DNA molecule have a pKa of ~2.14. Normal physiological pH in most cells is 7.0-7.5, which is significantly above the pKa for the phosphate groups, so every phosphate group in the backbone of both strands of a DNA molecule is deprotonated and carries a -1 charge - but DNA in cells is normally double-stranded. Briefly explain, in your own words, why the large negative charges on the backbones of the two strands of a double-stranded DNA molecule don't cause the strands to separate under normal cellular conditions.

What nucleobases are used in RNA. 3 Draw ATP and abbreviate the nucleobase with A. 4 Draw the synthesis of th edinucleotide formed between ATP and GMP. the 5' triphosphate can be abbreviated, but the monophosphate at the reaction centre should be expanded.

Which statements are true? Explain why or why not.1 Because the DNA double helix is only 2 nm wide—well below the limit of resolution of the light microscope—it is impossible to see chromosomes in living cells withoutspecial stains.2 A fluorescent molecule, having absorbed a singlephoton of light at one wavelength, always emits it at a longer wavelength.
