Not sure what this question is looking for, but possible correct answers would be inferior or maybe even distal
Degeneracy
Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 <span>nucleotides that codes for a specific amino acid.
Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. </span>
A mushroom-shaped landform
consisting of a column of less resistant rock supporting a broader extent of
wind-resistant rock is termed a yardang. Yardangs form in environments where
prevailing winds are strong and move in a single direction. Yardangs occur in
various deserts of the world such as the Turkistan and the Mojave deserts.
