Draw the 3 types of bonds in DNA, where each bond is positioned, and put them in order of their strengths? I know the 3 types of Bonds and strength wise but can you help explain everything else and also check if I am right? 1. Covalent Bonding ( most strongest) 2. Hydrogen Bonding( 2nd Strongest/middle) 3. pi-pi Interaction bonding ( weakest)

DNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?
Chemical analysis shows that a nucleic acid sample contains A, U, C, and G. Is this DNA or RNA? Why?
DNA, the carrier of genetic information in living things, has been used in criminal justice for decades. But how, exactly, does DNA profiling work? Given a sequence of DNA, how can forensic investigators identify to whom it belongs? Well, DNA is really just a sequence of molecules called nucleotides, arranged into a particular shape (a double helix). Each nucleotide of DNA contains one of four different bases: adenine (A), cytosine (C), guanine (G), or thymine (T). Every human cell has billions of these nucleotides arranged in sequence. Some portions of this sequence (i.e. genome) are the same, or at least very similar, across almost all humans, but other portions of the sequence have a higher genetic diversity and thus vary more across the population. One place where DNA tends to have high genetic diversity is in Short Tandem Repeats (STRs). An STR is a short sequence of DNA bases that tends to be repeated back-to-back numerous times at specific locations in DNA. The number of times…
Which DNA double helix do you think would be harder to separate into two strands? DNA composed of predominantly or GC base pairs. Why?
When DNA is heated, it denatures; that is, the strands separate because hydrogen bonds are broken and some base-stacking and hydrophobic interactions are disrupted. The higher the temperature, the larger the number of hydrogen bonds that are broken. After reviewing DNA base pair structure, determine which of the following molecules will denature first as the temperature is raised. Explain your reasoning. a. 5′-GCATTTCGGCGCGTTA-3′ 3′-CGTAAAGCCGCGCAAT-5′ b. 5′-ATTGCGCTTATATGCT-3′ 3′-TAACGCGAATATACGA-5′
In your own words describe the various types of bonds that are found in the structure of DNA and the roles they play in stabilizing the DNA molecule. Describe the chemical nature of the DNA molecule as best as you can.
Why do you think it is important that the sugar-phosphate backbone of DNA be held together by covalent bonds while the two strands of double stranded DNA are held together by hydrogen bonds?
When DNA is heated sufficiently, the strands separate. The energy that it takes to separate the DNA is related to the amount of guanine and cytosine bases. Why is this so? (A) Adenine and thymine make 3 hydrogen bonds between each other, and guanine and cytosine don't make any hydrogen bonds. (B) Guanine and cytosine make 3 hydrogen bonds between each other, and adenine and thymine don't make any hydrogen bonds. (C) It takes more energy to break an A-T bond than it does a G-C bond. (D) It takes more energy to break a G-C bond than it does an A-T bond.

draw a picture of a SINGLE strand of DNA (a polynucleotide) composed of 9 (nine) nucleotides of your choice. Do use ALL 4 nucleotides. Use 3 simple symbols to represent the phosphate, the sugar, and the base in each nucleotide. For example, use a circle with the letter “P” for the phosphate in the backbone, a square with the letter “S” for the sugar in the backbone, and a triangle with the letter “A, T, C or G” for the bases.As you draw the diagram be sure to put solid lines for the covalent bonds you are creating to join new nucleotides to the elongating DNA chain.
