Pseudodiploid or pseudoploid refers to one of the essential components in

The term is also used to refer to cells that are

Overview

Retrovirions for example are considered pseudoploid – they have two genomes within each capsid, but in general only one provirus is seen after infection with a single virion.

Retrovirus particles contain two copies of the RNA genome held together by multiple regions of base pairing (strongest pairing at 5’ ends) which is also called 70S complex (

nucleocapsid
protein that may function like a single stranded binding protein and therefore enhances processivity and facilitates template exchanges. The nucleocapsid first organizes RNA genomes within the virion and then facilitates reverse transcription within the infected cell.
