Virus is released from the host cell by budding.
(host cell mbn with incorporated HA and NA surround the nucleocapsid and buds off to form viral envelope)

NA cleaves the receptors containing sialic acid, allowing the mature viruses to be released. ]]> 2021-04-19 05:35:42 UTC https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431564986 https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431565267 - the influenza virus is released from the host cell by budding. - The host cell membrane with incorporated H and N surround the nucleocapsid and buds off to form the viral envelope

The virus is enclosed in an endocytotic vesicle. The viral envelope will fuse with the membrane of the endocytotic vesicle and release the nucleocapsid into the cytoplasm.]]> 2021-04-19 05:35:50 UTC https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431565312 https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431569297 HIV:
the virus buds off from the host cell mbn as it surrounds the HIV (+) sense ssRNA and proteins, acquiring their envelope from portions of the host’s cell mbn with gp120 (and gp41)]]> 2021-04-19 05:37:16 UTC https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431569297 https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431570128 Capsid proteins is assembled around the (+)sense ssRNA strands and enzymes to form new nucleocapsids. For example, assembly of HIV involves reverse transcriptase , integrase and protease. The nucleocapsids move to the cell surface membrane where the viral envelope glycoproteins have earlier been synthesised and embedded.]]> 2021-04-19 05:37:36 UTC https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431570128 https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431571711 -attachment sites on the T4 and lambda tail fibres bind to the complementary specific receptor sites on host bacterium cell
-haemagluttinin (HA) on influenza facilitates attachment of virus to host cell membrane by binding to specific receptors containing sialic acid
-the glycoprotein 120 (gp 120) on the HIV envelope binds specifically to complementary CD4 receptors found on the host CSM and this leads to fusion of the HIV envelope to the host’s CSM via gp 41]]> 2021-04-19 05:38:15 UTC https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431571711 https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431578480 In influenza,newly synthesised viral mRNA are translated into glycoproteins(NA and HA) on ribosomes on surface of the RER. The proteins are then secreted through the Golgi apparatus onto the cell surface via golgi vesicles. At the cell membrane,they are incorporated and cluster in patches.likewise in hiv newly synthesised gp120 and 41 will then be embedded into the cell membrane .hence cell membrane provide a site for protein to embed

For HIV,nuclear envelope provides compartmentalisation which provides a suitable optimum environment to allow viral RNA transcription to occur.]]> 2021-04-19 05:41:02 UTC https://padlet.com/resma_gulzar_mohd/oi4g7go1k0xm6aqn/wish/1431578480
