The structure of the HIV cell is two copies of single-stranded RNA enclosed by a conical capsid comprising the viral protein p24.
How Does The Virus Attach Itself To a Host Cell?
HIV attaches to its host cell when it comes into contact with a T-cell. It then must attach itself to the cell so that it is able to fuse with the cell and inject its genetic material. The attachment is a specific bonding between the proteins on the surface of the virus and proteins that serve as receptors on the surface of the T-cell, these receptors are normally used to help to cell communicate with other cells.
The Process The Virus Undergoes To Replicate
When HIV cells replicate they go through a process of budding. Budding is the formation of a new organism by the protrusion of part of another organism, because of this the daughter cell is identical to the parent cell. First HIV genetic material is gathered up with newly made HIV proteins and enzymes to form new viral particles which are then released from the cell. Then an enzymes protease chops up long strands of protein into smaller pieces which are then used to construct mature viral cores. Finally the matured cores are ready to infect other cells and begin the replication process all over again. The process is very quick and spreads very rapidly through out the human body.

Your blog has well constructed information and good pictures showing HIV. I think you could have had a bit more info but what information is there, is very good.
ReplyDeleteGood job Ashley =)
Looks good so far! What is budding? How does it go from an RNA viral genome to using incorporating into the DNA genome of the host?
ReplyDeleteGood information. Is this an example of the lytic cycle or the lysogenic cycle?
ReplyDeletewhoa! seriously a laarge amount of info.I felt like i was reading a harry potter book.... anyways it was well constructed and the information was definately there. So there is no way to cure it eh? thats shitty. What are some good ways to prevent the disease from spreading throughout the human population?
ReplyDeleteLots of information and it is well presented. Pictures are good and everything seems to be in place. Are they close to finding a cure for this virus?
ReplyDeleteThe structure of a virus compared to the structure of E. Coli is that a virus has its nulcleic acids inside of a protein coat called a capsid while E. Coli is created in the body and can be very dangerous it ingested
ReplyDeleteSo far they are trying to find a cure but I was unable to find any progress made. In terms of preventing it from spreading don't share needles, have protected sex and if there is any chance of you being exposed get tested right away because you may be able to save a couple years of you life.
ReplyDeleteGood job girls! answers all of the questions and has lots of good pics :)
ReplyDeletereally informative and easy to read, good job girls :)
ReplyDeleteIt was during my research on HIV/Herpes that I stumbled upon the Hiv/Herpes information; information which is quite easy to find when doing a search for STD on google.

I asked questions about the Herbal cure's on official HIV/Herpes websites and I was banned for doing so by moderators who told me that I was parroting Hiv/Herpes propaganda.
