The nemamiriro nemavhairasi uye sangano ravo

The nemamiriro Utachiona asiri cellular, sezvo ivo regai kuva organelles. Muchidimbu, ndiko Transitional Danho pakati akafa uye mupenyu nyaya. Nemavhairasi pazvakawanikwa Russian zvipenyu Di Ivanovo muna 1892 mune muitiro pokuongorora fodya waMosesi chirwere. All sechivako nemavhairasi - RNA kana DNA iri akanyudzwa imwe puroteni goko inonzi capsid. Akadana virion akaumba rwarisa inoramba.

Influenza nemavhairasi kana herpes vane chimwezve lipoprotein hamvuropu, izvo unovapo kubva cytoplasmic Kamudzira wehondo masero. Nemavhairasi vari dziya mu DNA tubhokisi kana RNA tubhokisi, nekuti vanogona mumwe chete mhando nucleic acid. Zvisinei, zvakawanda nhamba nemavhairasi - ari RNA tubhokisi. genomes dzavo dzine nezano uye kaviri-nezano. The womukati maumbirwo nemavhairasi zvinovabvumira muwande chete masero mamwe zvipenyu, uye hapana mumwe. Havana vanoratidza extracellular basa. Sizes rinoparadzirwa nemavhairasi - kubva 20 kusvika 300 nm mu dhayamita.

Sechivako nemavhairasi bacteriophages

Nemavhairasi kuti zvirwere utachiona mukati, akadana bacteriophages (phages). Vanokwanisa zvinopfuura kwemabhakitiriya sero uiparadze.

Chitunha bacteriophage pamusoro E. coli ane musoro umo negomba tsvimbo, akaputira pabutiro contractile mapuroteni. Panoperera tsvimbo iyi basal ndiro riri iro 6 tambo yakasimbiswa. Inside musoro ane DNA Morekuru. Achishandisa anokosha pezvakaitwa bacteriophage utachiwana wanamatira muviri utachiona Escherichia coli coli. Kushandisa chaiyo enzayemu, kuti phage urwa muchitokisi rusvingo uye chinopinda nechomukati. Next, tsvimbo kubva mugero Akaroromesawo musoro jetted morekuru reDNA, uye mukati mumaminitsi 15 bacteriophage zvachose kusiyiwa kumira zvakare refu muviri mabhakitiriya masero ari zvaaida nzira. Utachiona haasisina synthesize DNA waro - zviri ikozvino synthesizes munhu nucleic asidhi kweutachiwana. izvi zvose rapera nokuti pane vamwe 200-1000 vanhu phages uye utachiona Sero raparadzwa. bacteriophages All vari rakakamurwa virulent uye vakadzikama. Ekupedzisira havaiti kuberekana mumasero mabhakitiriya uye virulent chimiro kuchizvarwa vanhu kare kutapukirwa nzvimbo.

nemavhairasi zvirwere

The nemamiriro utachiona uye zvokurarama nazvo anokonzerwa yokuti vanogona kuvapo chete masero mamwe zvipenyu. Kugara chero muchitokisi, utachiona inogona kukonzera chirwere chakakomba. Vari kazhinji pasi kurwisa Zvirimwa zvokurima uye mhuka. zvirwere izvi zvinoshamisa kanganisa kuorera zvirimwa uye ndiwo anokonzera dzakawanda kufa mhuka.

Pane nemavhairasi anogona kukonzera zvirwere zvakasiyana-siyana muvanhu. Munhu wose ajaira zvirwere zvakadai sechibhokisi, herpes, yokuSpain, poriyo, mumps, gwirikwiti, jaundice uye AIDS. Vose muka kubva wanda. The nemamiriro chibhokisi utachiwana haasi zvakasiyana chaizvo kubva nemamiriro herpes utachiona, sezvo ivo ndezvaJehovha chete boka - kupisa nokuvava Virus, izvo zvinosanganisira kunyange dzimwe mhando wanda.
