Explain the meaning of genetic code, and describe how thegenetic code functions.
a. Explain the one gene-one polypeptide theory.
b. The DNA sequence of a gene determines the sequence of aminoacids in a polypeptide chain. What studies have demonstrated thisrelationship?
c. In what molecule are codons found? How many nucleotides are ineach codon? How many nucleotides are available to make up eachcodon? How many different types of codons are possible? How manyamino acids are specified by one codon? Theoretically, how manydifferent amino acids could be coded? How many different aminoacids are available? Given this information, is it possible thateach amino acid is coded by more than one codon?
d. Would a mutation involving deletion of one nucleotide affect theamino acid sequence of the corresponding peptide? Would deletion ofa sequence of three nucleotides have a similar effect? What doesthis fact say about the nature of the genetic code?
(please answer all the questions above thank you!)
