An apricot is a fruit or the tree that bears the fruit of several species in the genus Prunus (stone fruits). Usually, an apricot tree is from the species P. armeniaca, but the species P. brigantina, P. mandshurica, P. mume, and P. sibirica are closely related, have similar fruit, and are also called apricots. Apricot tree in central Cappadocia, Turkey.
An icosahedral virus is a virus consisting of identical subunits that make up equilateral triangles that are, in turn, arranged in a symmetrical fashion. A special type of icosahedral shape, called a prolate, is a variant of the icosahedral viral shape and is found in bacteriophages.rtem is a doctor of veterinary medicine and has taught science and medicine at the college level. Learn about the different shapes viruses can have, such as helical, icosahedral, prolate, complex and enveloped. Find out why one shape is particularly useful from an energetic standpoint.
A DNA virus is a virus that has DNA as its genetic material and replicates using a DNA-dependent DNA polymerase. The nucleic acid is usually double-stranded DNA (dsDNA) but may also be single-stranded DNA (ssDNA).DNA viruses belong to either Group I or Group II of the Baltimore classification system for viruses.Single-stranded DNA is usually expanded to double-stranded in infected cells.ll viruses in this group require formation of a replicative form â a double stranded DNA intermediate â for genome replication. This is normally created from the viral DNA with the assistance of the host's own DNA polymerase.
