Chromatin is the component that specifies the nuclear contents during inter-phase.
<u>EXPLANATION:</u>
- The term inter-phase is the type of phase in which the cells would exhibit in all parts of its life.
- Chromatin is a term used to explains the components and contents of the nuclear in its inter-phase.
- A cell grows normally and duplicates its internal structure, the DNA, during inter-phase.
- Then it divides during the phase called mitosis after inter-phase.
Answer:
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.

The answer is Catecholamine. It is any of a class of aromatic amines that includes a number of neurotransmitters such as epinephrine and dopamine. The adrenergic receptors are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine (noradrenaline) and epinephrine (adrenaline). These three - catecholamine, peptide hormones and eicosanoids acts as extracellular membrane receptors which means that these receptors are embedded in the membranes of cells. They act in cell signaling by receiving (binding to) extracellular molecules.
It involves a systematic process
Answer: 5 prime cap
Shortly after RNA polymerase begins to transcribe a pre-mRNA, a 5 prime cap is added.
