Answer:
DNA → TACCATGGAATTACT
RNA → AUGGUACCUUAAUGA
PROTEIN → Methionine-Valine-Proline-Stop codon-Stop codon (AUG GUA CCU UAA UGA)
Explanation:
In nucleic acids (i.e., DNA and RNA), base complementarity refers to the interaction between antiparallel strands. In the double helix DNA molecule, adenine always interacts with thymine (uracil in RNA), while cytosine always interacts with guanine. Moreover, amino acids are encoded by codons, i.e., triplets of nucleotides in the messenger RNA (mRNA). Finally, stop codons are triplets of mRNA nucleotides (e.g., UAG, UAA, UGA) that indicates the end of the protein-coding sequence.
Answer:
Random mutations led to evolution of pesticide resistance genes in bed bugs.
Explanation:
Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.
A mutation is one form of genetic variation.
