Which is on one end of all trna molecules

anticodon 3'-UAC-5'

Explanation:

The tRNA molecule is Transfer ribonucleic acid. This tRNA molecule decodes information present in the mRNA to proteins. During the time of translation, the tRNA molecule works at a specific site. This molecule has two ends.

The anticodon 3'-UAC-5' is present at the one end of tRNA. The anticodon binds to the mRNA codon with a complement sequence, 5'-AUG-3'. The second end of tRNA molecule attached with methionine (amino acid). The AUG codon in mRNA specifies the amino acid methionine.

Plant roots are also an important source of chemical weathering. As roots expand into rock, acids can change the minerals in the rock. Plant roots also use carbon dioxide, thus changing the chemistry of the soil. New, weaker minerals are often more brittle; this makes it easier for plant roots to break up the rock.
