The melting temperature of DNA is the temperature at which half of the DNA strands are in a random coil or single-stranded configuration. Determine whether the following statement is true or false, and state your reasoning.
Longer strands of DNA have a lower melting temperature than shorter ones.
Which of the following statements about base pairing is incorrect?
True or False: When two bases have the same amount, they are complementary base.
A student analyzed the DNA composition of a sea cucumber. He found out that the sea cucumber's DNA has 16% T and about 34% G. What percentage of A and C would he expect in the sea cucumber's DNA?
A student analyzed a double-stranded DNA molecule and found out that the DNA has 19% C. Determine the percentage of G, A, and T. Explain.
What is the complementary DNA base sequence if the original segment is A G T C A C G T T A G C?
In a certain species of bacteria, it is found that 30% of the DNA base pairs are composed of guanine. What is the percentage of adenine, thymine, and cytosine in the DNA of this bacteria?
If the base sequence of the original segment is T A C G G C A T T A G T, what is the base sequence of the complementary DNA segment?
