It's a T4 long fiber and it attaches to the cell wall of the host
No.
No. Rabies virus does not penetrate the intact skin. Also tail of the dog do not carry the virus.
carrot fiber
the function of a tail is to lift its body and to increase the speed of flight
Tail pins in bacteriophages help the virus attach to the host bacterial cell by interacting with specific receptors on the cell surface. Once attached, the tail pins facilitate the injection of the viral genetic material into the host cell for replication.
Carrot fiber
It function is to make mRNA and acts as a jet preppeled motor to help the virus move.
The function of spike proteins is to imitate a protein your cells take in to allow the virus access to the nucleus.
A virus carries out the function of replication, by hijacking the host cell's machinery to make copies of itself.
Tail sheath acts as a cell membrane to the sperm.
It is a T4 long fiber, which is highly homologous to the tip of the bacteriophage lambda side tail fibers. This structure reveals an unusual elongated six-stranded antiparallel beta-strand needle domain containing seven iron ions coordinated by histidine residues arranged colinearly along the core of the biological unit. At the end of the tip, the three chains intertwine forming a broader head domain, which contains the putative receptor interaction site. The structure reveals a previously unknown beta-structured fibrous fold, provides insights into the remarkable stability of the fiber, and suggests a framework for mutations to expand or modulate receptor-binding specificity.
