What is the structure of a virus?​

Biology
1 answer:
NikAS [45]3 years ago
4 0

Answer:

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

A virion consists of a nucleic acid core, an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell. The capsid is made up of protein subunits called capsomeres. Viruses may also contain additional proteins, such as enzymes

Alex Ar [27]

Answer:

<u>Priming</u> refers to the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response

Explanation:

Priming is an effect related to the reaction or response to a certain stimulus may be conditioned by another previous stimulus, which is unconscious, that is, it is to expose someone to a certain stimulus that, without that person being aware of this, it will influence the response to subsequent stimuli. This circumstance is known as priming, and it is a phenomenon related to implicit memory (type of memory that is unconscious and involuntary) and is the most common way to evaluate it. Repeat priming has been preferably studied until recently using verbal stimuli presented in a visual or auditory manner. Implicit memory has been evaluated through a series of tests consisting of word associations.
