The figure shows the bonding of the cytosine and guanine molecules. The O - H and H - N distances are each 0.110nm. In this case, assume that the bonding is due only to the forces along the O - H - O, N - H - N and O -H- N combinations, and assume also that these three combinations are parallel to each other.Calculate the net force that cytosine exerts on guanine due to the preceding three combinations.
Estimate the cytosine content in turtle DNA if guanine = 25.2% and thymine = 24.8%. Your Answer: % nos < Prey 43 of 48 Next >
(a) Draw the structures of Uracil, Cytosine, Adenine and Guanine. (b) on your structures indicate the source of every nonhydrogen atom from the de novo pathways of nucleotide biosynthesis.
A piece of single-stranded nucleic acid contains adenine, cytosine, and guanine. Which piece or pieces of information below would tell you if it was RNA or DNA? The ratio of cytosine to guanine Whether uracil is present Whether the pentose sugars in the nucleotides have 3' OH groups The ratio of adenine to cytosine The number of phosphate groups in a piece of the nucleic acid 100 nucleotides long Whether the pentose sugars in the nucleotides have 2' OH groups
In RNA, uracil forms a complementary base pair with O guanine thymine adenine cytosine
Adenine, cytosine, guanine are present in both DNA and RNA. Thymine and uracil are exclusive for DNA and RNA respectively. Explain why it is advantageous for DNA to contain thymine, not uracil. 0. Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints. Gout happens when uric acid builds up in your body. It is treated with allopurinol. What is the biochemical bas is of this treatment?
The following pairing of DNA nucleotides is correct, except ___________. Adenine with thymine Cytosine with guanine Purine with pyrimidine Guanine with adenine DNA nucleotides with one-carbon nitrogen ring bases are called ________. adenines purines pyrimidines guanine The nucleotides of DNA are held together by ___________. ionic bond hydrogen bond phosphodiester bond sugar-phosphate backb Basic structure of nucleotide includes the following type(s) of chemical components. Phosphate group Deoxyribose sugar Nitrogenous base All of the above
the entire mRNA strand that codes for collagen consists of 5% adenine, 30% guanine, 40% cytosine, and 25% uracil. what is the avergae percentage of the entire DNA strand (double helix DNA, meaning the template starnd plus the non template strand)that would be cytosine?
Adenine 0-P=0 Thymine Lo O=r-o Sugar-phosphate backbone Sugar-phosphate backbone Cytosine O-P=0 Guanine 0 NH O=P-O 0-- Nitrogenous bases Where are the hydrogen bonds found in this DNA molecule? between C and H in the nucleotide cytosine between H in cytosine and O in guanine between N and H in the nucleotide containing guanine between H in guanine and N in cytosine
PCR 7- Genomes are frequently described according to their GC content. G (guanine) and C (cytosine) make triple hydrogen bonds in the double helix, whereas thymine and adenine make double hydrogen bonds. Would you expect to program a thermal cycle the same way for an organism with 50% GC as an organism with 25% GC? If yes, why? If not, what would you change? 8- What molecules are present in the cell that might interfere with DNA extraction?
