Degeneracy
Degeneracy indicates that several codons can encode for the same amino acid during the process of protein synthesis from DNA. A codon comprises a triplet of <span>nucleotides that represents a specific amino acid.
This redundancy means that mutations (like point mutations) are less likely to disrupt the synthesis of proteins. For instance, if the codon sequence GAA, which represents glutamate, changes to GAG, glutamate will still be produced as the code is degenerate. </span>
Response:
2, 1, 4, 3.
Explanation:
The cell membrane potential can be described as the difference in electric gradient between the inside and outside of the cell. Ions play a critical role in creating this voltage difference.
Transmission of nerve impulses occurs through propagation. The cell maintains a resting membrane potential. The opening of sodium channels allows the inward movement of sodium ions, increasing the positivity of the membrane potential and causing depolarization. Subsequently, potassium ions begin to diffuse into the cell while sodium ions exit, resulting in the cell's repolarization.
Thus, the correct sequence of events is 2, 1, 4, 3.
Answer:
Paraquat serves as a herbicide.
Explanation:
Coral bleaching wasn't induced by paraquat since it is a herbicide aimed at eliminating weeds, not algae. Coral hosts small algae essential for its coloration, hence applying paraquat wouldn't affect these algae, thus preventing coral bleaching. In contrast, if a different chemical that targets algae is used, it results in coral bleaching and turns the coral white.
