Nucleotides makes up each individual strand of DNA
They are the endocrine glands
The cellular response to the second messenger is a mutation that affects ca++ binding to calmodulin and is most likely to interfere with what aspect of a signal transduction pathway.
<h3>Ca++ binding to calmodulin :</h3>
This protein-protein interaction ultimately has a physiological consequence; for instance, in smooth muscle, Ca2+ binding to calmodulin causes it to connect with and activate myosin light chain kinase, which in turn catalyzes the phosphorylation of myosin. The smooth muscle contracts as a result of this reaction.
A common, tiny (148 amino acids) calcium signaling protein called calmodulin (CaM) controls the actions of numerous cellular proteins. It has two calcium-binding sites in the N-domain (I and II) and two more in the C-domain (III and IV).
In order for smooth muscle to contract, calmodulin is crucial for excitation-contraction (EC) coupling and the start of the cross-bridge cycling in smooth muscle. The head of the myosin light chain must be phosphorylated to initiate smooth muscle contraction.

Answer: <u> Atomos</u>
Explanation: Matter is composed of indivisible building blocks. This idea was recorded as early as the fifth century BCE by Leucippus and Democritus. The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term.
