mr Goodwill [35]

The question is incomplete as it does not have the options which are:

(a)DNA (b)tRNA (c)rRNA (d)mRNA

Answer:

Option-mRNA

Explanation:

The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.

The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.

This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.

Thus, mRNA is correct.
