" hormone is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior. hormones have diverse chemical structures, mainly of 3 classes: eicosanoids, steroids, and amino acid derivatives." Hope this helps-

Explanation:

Hormones are the chemical messengers that coordinate complex processes like fertility, growth and metabolism by traveling throughout the body. Hormones are secreted directly into the blood by the glands, in reaction to the signals received from the brain. All cells in the bloodstream are exposed to the hormones,but only a hormone's target cell reacts, which have receptors for that hormone. Hormone disrupting chemicals can act at any point along this pathway. Some of them are mimic, which sends a false signal by binding the receptor that is not commanded by the brain.

Total nucleic acids are extracted from a culture of yeast cells and are then mixed with resin beads to which the polynucleotide

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.
