In this manner, what does negative RNA mean?

Medical Definition of Negative-strand RNA virus Negative-strand RNA virus: Also known as an antisense-strand RNA virus, a virus whose genetic information consists of a single strand of RNA that is the negative or antisense strand which does not encode mRNA (messenger RNA).

Subsequently, question is, what do you mean by plus and minus strand RNA viruses? 1. in a single-stranded RNA virus, a plus strand is one having the same polarity as viral mRNA and containing codon sequences that can be translated into viral protein. A minus strand is a noncoding strand that must be copied by an RNA-dependent RNA polymerase to produce a translatable mRNA.

Herein, what is positive and negative sense virus?

Viruses with ssRNA genomes that can act directly as mRNA are known as positive-sense RNA viruses (abbreviated +ssRNA). Similarly, ssRNA viruses with genomes that are not able to be immediately translated by ribosomes are known as negative-sense RNA viruses (abbreviated -ssRNA).

What does positive sense virus mean?

A positive-sense single-stranded RNA virus (or (+)ssRNA virus) is a virus that uses positive sense, single-stranded RNA as its genetic material. The positive-sense viral RNA genome can serve as messenger RNA and can be translated into protein in the host cell.
