- DNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?In general, which part of a DNA sequence will have the best quality? (Ex. Beginning, middle, end?) Why?DNA sequences have an alphabet {A,C,G,T}. How many DNA sequences of length n are there? (Two DNA sequences are the same if one is the reverse of the other).
- What is palindromic sequence of DNA?a) Explain the effect of the guanine:cytosine ratio on melting temperature of DNA. b) The Hershey-Chase experiment proved that DNA is the genetic material and not protein. Explain in detatil how this experiment was conducted.In 1950, Edwin Chargaff discovered that the ratios of A:T bases, and of G:C bases, in DNA is always 1:1. This discovery became known as Chargaff's rules and was important in helping determine the structure of DNA. The percentages of adenine (A), cytosine (C), guanine (G) and thymine (T) bases in DNA from three species are shown below. Select the best answer for each of the questions. Q1: Does the distribution of nucleotide bases in species 1 and 2 in the table follow Chargaff’s rules? Why or why not? Q2: Based on the information in the table, what is the % cytosine in species 3?
- What are the exceptions to the general rule that DNA is the genetic material in all organisms? What evidence supports these exceptions?A duplex DNA molecule contains a random sequence of the four nucleotides with equal proportions of each. What is the average spacing between consecutive occurrences of the sequence 5'-ATGC-3'? Between consecutive occurrences of the sequence 5'-TACGGC-3'?The underlying structure of DNA is very simple, consisting of only four possible building blocks. a. How is it possible for DNA to carry complex genetic information if its structure is so simple?
