A long, collection of genes that carries heredity information and is formed from condensed chromatin.
lukranit [14]

Answer:

RNA-Ribonucliec acid

Explanation:

RNA is a chromosome is a darkly stained structure present in the cell which carries the genetic information of the organism.

The chromosome is a condensed or packaged form of the structure formed by the condensation of a thread-like structure called chromatin which attaches at a point and gives X shaped appearance to the chromosome. This packaging is necessary for the cell as it helps transfer the long sequence of DNA during cell division.

The RNA is composed of the DNA which acts as the genetic material of the cell and the proteins which help bind the DNA in a tightly folded manner.

Which subtype of type a fibers transmits signals that are interpreted and perceived as pain?
borishaifa [10]

Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.

<h3>Delta fibres</h3>

A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.

Structure

They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.
