|March 1, 1980
Abstract:
Influenza virus nucleoid ("core") was obtained by the treatment of virions with hydrolytic enzymes without the use of fixing agents. The "core" buoyant density in sucrose density gradient was 1.24 g/cm3. The subvirus particles are completely devoid of surface proteins, glycoproteins, and their polypeptide composition is represented by group P proteins; NP and M proteins. RNA in the core is insensitive to the effect of RNase. Morphological analysis by electron microscopy revealed the presence of spherical compact particles without spikes on their surface.

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...
