Using the codon chart shown below, decipher the code GGU GGA UGG. Make the second strand of DNA. Make a strand of RNA.
Understand the Problem
The question is asking for a decoding of a DNA sequence based on a provided codon chart. Specifically, it involves deciphering the amino acids represented by a given sequence of bases, making a second strand of DNA, and including a mutation in that second strand.
Answer
Amino acids: Glycine, Glycine, Tryptophan. DNA: CCT CCT ACC. RNA: GGU GGA UGG.
The codons GGU and GGA code for Glycine, while UGG codes for Tryptophan. The second strand of DNA complementary to the original strand would be CCT CCT ACC, and the mRNA strand would be GGU GGA UGG.
Answer for screen readers
The codons GGU and GGA code for Glycine, while UGG codes for Tryptophan. The second strand of DNA complementary to the original strand would be CCT CCT ACC, and the mRNA strand would be GGU GGA UGG.
More Information
Codons are sequences of three RNA bases coding for specific amino acids. The genetic code is universal in most organisms.
Tips
Ensure correct base pairing: A pairs with T (U in RNA), and C pairs with G.
