Swine Flu Virus Photo – H1N1 Photo

Swine flu virus is an influenza virus. H1N1 Swine flu virus is an influenza A virus. You can learn the parts of swine flu virus in this photo. That is swine flu virus photo.

Swine flu virus photo - H1N1 photo

The parts of H1N1 (swine flu) photo.

PB2 is an avian polymerase. PB1 is avian and human polymerase. PA is an avian polymerase. HA is human or swine origin. NP is swine origin. NA is a human or swine origin. M and NS are swine origin.

There are “helps initiate infection” and “binds to receptors on host cells” parts.

Most countries have all reported first H1N1 deaths in their countries. You can protect yourself against H1N1 swine flu virus.

Just for laugh. This swine flu virus image is from Winnie the pooh cartoon. Piglet is sad about it.

SWINE FLU SYMPTOMS – SYMPTOMS OF SWINE FLU

Symptoms of swine flu are very similar to those of seasonal influenza. If you feel ill, stay home from work and school. Because an infected person can shed the virus 24 hours before symptoms start, and up to seven days later. If you exhibit symptoms and believe you may have swine flu, call your physician before making a trip to see him or her, then follow advice on how to proceed.

Single Human Chromosome Photo

Single human chromosome

A single human chromosome photo. Have you ever seen a chromosome? Lots of people know, humans have 46 chromosomes but someones know chromosome photo. There is a photo of it. If you wonder the shape of chromosome you can look at this. What is the shape of a chromosome? Maybe this photo is useful for your research, investigation.

Chromosomes are very important objects of human bodies. Chromosomes are not specific for species. Two species can have same number of chromosomes but the important thing is: How many genes in a chromosome?

They are like bookcase. You can put 20 books on it or if you want you can put 30 books. In others words, number of chromosomes are not important. The important thing is number of genes… Genes include DNA.

Plasmid DNA on a Mineral Sheet Photo

Plasmid DNA on a mineral sheet, Computational simulation, Circular plasmid DNA on a mineral sheet, studied using molecular dynamics simulations to see whether the sheets can protect the DNA against extreme conditions such as those found in deep ocean hydrothermal vents. If they do it would lend support to the idea that a group of minerals called Layered Double Hydroxides could be an ideal protective and catalytic scaffold for the creation of biological molecules and hence the origin of life.

A plasmid is an extra-chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently of the chromosomal DNA. In many cases, it is circular and double-stranded. Plasmids usually occur naturally in bacteria, but are sometimes found in eukaryotic organisms (e.g., the 2-micrometre-ring in Saccharomyces cerevisiae).

Plasmid size varies from 1 to over 200 kilobase pairs (kbp). The number of identical plasmids within a single cell can be zero, one, or even thousands under some circumstances. Plasmids can be considered to be part of the mobilome, since they are often associated with conjugation, a mechanism of horizontal gene transfer.

Human Immunodeficienncy Virus (HIV) Photo

Human immunodeficiency virus (HIV) is a retrovirus that can lead to acquired immunodeficiency syndrome (AIDS), a condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infections. Previous names for the virus include human T-lymphotropic virus-III (HTLV-III), lymphadenopathy-associated virus (LAV), and AIDS-associated retrovirus (ARV).

Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. The four major routes of transmission are unprotected sexual intercourse, contaminated needles, breast milk, and transmission from an infected mother to her baby at birth. Screening of blood products for HIV has largely eliminated transmission through blood transfusions or infected blood products in the developed world.

Molecular Model of a Ribosome Photo

Molecular model of a ribosome photo

Molecular model, Molecular model of a ribosome, Molecular model of a bacterial ribosome showing the RNA and protein components in the form of ribbon models. In the large (50S) subunit the 23S RNA is shown in cyan, the 5S RNA in green and the associated proteins in purple. In the small (30S) subunit the 16S RNA is shown in yellow and the proteins in orange.

The three solid elements in the centre of the ribosome, coloured green, red and reddish brown are the transfer RNAs (tRNAs) in the A, P and E sites respectively. The anticodon loops of the tRNAs are buried in a cleft in the small subunit where they interact with mRNA.

The other ends of the tRNA, which carry the peptide and amino acid, are buried in the peptidyl transferase centre of the large subunit, where peptide bond formation occurs.

Ribosomes (from ribonucleic acid and “Greek: soma meaning body) are complexes of RNA and protein that are found in all cells. Prokaryotic ribosomes from archaea and bacteria are smaller than most of the ribosomes from eukaryotes such as plants and animals.

However, the ribosomes in the mitochondrion of eukaryotic cells resemble those in bacteria, reflecting the evolutionary origin of this organelle.

The function of ribosomes is the assembly of proteins, in a process called translation. Ribosomes do this by catalysing the assembly of individual amino acids into polypeptide chains; this involves binding a messenger RNA and then using this as a template to join together the correct sequence of amino acids.

This reaction uses adapters called transfer RNA molecules, which read the sequence of the messenger RNA and are attached to the amino acids.
