Human Genetic Material (DNA) Is Made Up of Sequences of the Molecules

question 12

Short Answer

Human genetic material (DNA) is made up of sequences of the molecules adenosine (A), guanine (G), cytosine (C), and thymine (T), which are called bases. A codon is a sequence of three bases.
Replicates are allowed, so AAA, CGC, and so forth are codons. Codons are important because each codon causes a different amino acid to be included in a protein.
a. How many different codons are there?
b. How many different codons are there in which all three bases are different?
c. The bases A and G are called purines, while C and T are called pyrimidines. How many different codons are there in which the third base is a purine and the others are pyrimidines?
d. What is the probability that all three bases are different?
e. What is the probability that the third base is a purine and the others are pyrimidines?
