mRNA has a complete nucleotide sequence so it is considered largest RNA.
Which DNA is soluble ?
Single stranded DNAs are soluble in 97% methanol and in acetone. A 45-mer DNA is more soluble than a 108-mer DNA, although the solubility is strongly dependent on the species and concentration of the salt used.
Concept: Why tRNA is also known as soluble RNA ?
Reason: tRNA or transfer ribonucleic acid is typically 76 to 90 nucleotides in length, which transfers the amino acid to mRNA and acts as connecting link between them. The tRNA is known as the soluble RNA as they are soluble in 1M NaCl.
