The auc and aua codons in mrna both specify isoleucine. what feature of the genetic code explains this?
complementarity
nonsense codons
universality
degeneracy

Degeneracy

Explanation:

As a result, codons have to "double up" and share amino acids because there is only a limited number of these that they can code for  

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
