What feature does man liver virus have _'s symptom

What feature does man liver virus have _'s symptom
Man liver virus one light the intersection of ribonucleic acid and virus, could duplicate and cause man type hepatitis in infecting with the intersection of hepatitis B and body of virus only. Studies have suggested liver, man of i, in the course that virus infect, man the intersection of liver and duplication of virus need the intersection of hepatitis B and virus offer bag the intersection of membrane and albumen, The man liver virus is a spherical particle, the diameter is 35 nanometers - 37 nanometers. Molecular weight only little the intersection of ribonucleic acid and the intersection of virus and 1/ 4 of genome. Can observe, the skin is antigenic lipoprotein parcel of surface of hepatitis B under the electron microscope. Man of molecule biological analysis liver ribonucleic acid single ring ribonucleic acid that covalent link closes of burst and by 1 678 bases to forming, structure and property of this ribonucleic acid having virus, can be separated and closed up under the regulation of magnesium ion automatically. This kind of decomposition is essential to the duplication of the liver virus ribonucleic acid of ring man; Have 9 to read one yard of frames (ORF) open at least on man's liver virus genome . Read one yard of frames 5(ORF5) in opening located in complementary burst of gene to find at present Can encode a piece of polypeptide which includes 215 amino acids to get the man liver antigen (HDAg) . The man liver antigen is a kind of nucleoprotein, the ability is hot and is able to bear the acid, but apt to be deactivated by protease and alkali. 1% chains of protease can make 96% of the cube liver antigen deactivate. Have antigenic specificity of better man's liver, can be detected in the liver and in serum, can be regarded as the man type peculiar foundation that diagnoses of hepatitis together with the cube liver antibody in serum.
