Answer:

tRNA

Explanation:

Messenger RNA is formed by a single chain of nucleotides, in contrasting to DNA, that has a double helix connoting several hydrogen bonds between chains. In this case mRNA doesn't compete with DNA hydrogen bonds, because it appears in a single chain.

In the case of tRNA, their secondary structure present domains with abundant hydrogen bonds forming hairpins, loops, bulges and so. In this way more interactions en the same molecule (tRNA) exist in different of their parts.

Study the following reaction carefully. What classification should this reaction have? 4Al + 3O 2 2Al 2 O 3

nikitadnepr [17]

The reaction is a synthesis…

$4Al + 3O_2 \longrightarrow 2Al_2O_3\\$

… because two substances are combining to make one other substance.

$4\stackrel{\hbox{0}}{\hbox{Al}} + 3\stackrel{\hbox{0}}{\hbox{O}}_2 \longrightarrow 2\stackrel{\hbox{+3}}{\hbox{Al}}_2\stackrel{\hbox{-2}}{\hbox{O}}_3\\$

It is also a reduction-oxidation reaction because the oxidation number of Al increases from 0 to +3 and the oxidation number of O decreases from 0 to -2.
