The information in DNA is copied onto RNA.
Much RNA is messenger RNA (mRNA), which leaves the nucleus and while in the cytoplasm becomes attached to ribosomes. At the ribosomes, polypeptide chains are assembled (synthesized), and from these, proteins are made.
There are many other kinds of RNA, all synthesized using DNA as a template. One example is the family known as transfer RNAs (tRNAs), that carry specific amino acids to ribosomes for assembly into polypeptides.
Steroid hormones such as estrogen, testosterone, and cortisol work by direct gene activation. These hormones can diffuse across the cell membrane, bind to intracellular receptors, and regulate gene expression by binding to specific DNA sequences. This process leads to changes in protein synthesis and cellular function.
No, direct gene activation typically does not involve a second-messenger system. Direct gene activation involves specific transcription factors binding directly to gene promoter regions to regulate gene expression. Second-messenger systems are typically involved in signal transduction pathways that lead to changes in protein activity or cell function, rather than directly activating genes.
Messenger RNA molecules are fed through the ribosomes during protein synthesis.
Immediately rinse the area with water to remove the unknown material from your skin. If the substance is a known irritant or hazardous chemical, consult a healthcare professional for further guidance on how to treat the exposure.
A stem cell differentiates by activating specific genes that direct its development into specialized cell types. This process involves epigenetic changes that determine which genes are turned on or off, leading to the formation of different cell types with specific functions.

The direct transfer of heat between two substances that are touching is conduction.
Conduction.
conduction
The process of direct transfer of substance from one touching substance to another is called conduction. Heat or electricity can be transferred through conduction when two substances are in direct contact with each other. This transfer occurs due to the collision of particles within the substances.
Conduction is the process by which heat is transferred through direct contact between adjacent molecules in a substance.
It is known as: conduction.

Physical changeschemical changesYou must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
Conduction. This process involves the transfer of heat from a warmer substance to a cooler substance when they are in direct contact. The particles in the warmer substance transfer energy to the particles in the cooler substance through collisions, leading to an overall transfer of heat.
The direct cause of a substance's temperature increase is the input of thermal energy, typically in the form of heat. This added energy increases the kinetic energy of the substance's molecules, causing them to move faster and leading to an increase in temperature.
