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.
Explanation:
The phospholipid bilayer forms the outermost layer of cells called the plasma membrane of the cell.
The phospholipids are arranged in the bilayer with the globular head composed of glycerol and the phosphate on the outer side (hydrophilic) and the hydrophobic carbon chain in the inner side.
The hydrophobic molecule present in the layer provides a characteristic feature to the membrane that is known as selective permeability. The selective permeability allows the non-polar or uncharged molecule to pass through the membrane and not the large polar molecules.
This is because the non-polar molecules can interact with the hydrophobic portion (tails) which could allow the molecules to pass through the membrane but the polar molecules are repelled by the hydrophobic protein so require special channels.
