Yintoni eyenza wahluke?

igawuthi

Jonga abahlobo bakho kwaye uzame ukuthelekisa. Ngaba bonke bajongeka ngokufanayo? Ngaba bafana nawe?



Abantu baneempawu ezahlukeneyo-ibala lolusu, ukumila kwendlebe, ubungakanani bempumlo, kwanombala wamehlo. Yintoni eyenza umntu ngamnye ahluke? Impendulo yiDNA okanye i-deoxyribonucleic acid.



I-DNA yimolekyuli ekhethekileyo exelela iiseli zakho ukuba zenzeni. Uneebhiliyoni zeeseli emzimbeni wakho ezincinane kakhulu ukuba ungazibona. Iseli nganye inomsebenzi wayo. Ngaphakathi iiseli kukho izakhiwo ezincinane ezibizwa ngokuba zii-chromosomes kwaye ngaphakathi kuyo yonke i-chromosome kukho amakhulu emfuza.

I-DNA injengaleli entle ejijekileyo amaxesha amaninzi. Ubume bayo bubizwa ngokuba yi-helix ephindwe kabini. Ihlelwe ngokwakhiwa kwee-chromosomes ezingama-46. Iichromosomes zakho zilungelelaniswe ngababini. Ilifa elinye ulifumene kunyoko kunye nelinye kuyihlo.

Malunga manqaku

Ngaba ungomnye waba bafundi bayoyika iSayensi? Ngaba ucinga ukuba akukho kumnandi ekufundeni iSayensi?

Ngokuhambelana nomsebenzi wayo, iBayer: Inzululwazi yoBomi obungcono, kunye nothando lwayo kuphando, iBayer ifuna ukudlulisela kubantu abancinci abanjengawe uvuyo lokufumanisa kunye nolonwabo ekufundeni. Ngokubeka iimvavanyo ezilula, zemfundo kunye nolonwabo, uBayer ukhuthaza abafundi bezikolo zamabanga aphantsi ukuba bafunde iSayensi ngokwenza iSayensi.



Uthotho lweBayer Smiling Kiddie Einsteins lunika abafundi, ootitshala kunye nabazali izandla kunye namava asekwe kuphando abandakanya ukujonga, ukuthelekisa, ukuhlalutya kunye nokuvavanya.

Ngolu ngcelele lovavanyo olunxulumene nempilo, isondlo kunye nendalo, iBayer kunye noMphandi wezeMfundo bajonge ukukhulisa umdla wabafundi abasaqalayo kwiSayensi.

Izinto ezifunekayo kolu vavanyo zikhuselekile kwaye zinokufikeleleka ngokulula kwikhaya lakho.

Uvavanyo

I-DNA ikhona kuyo yonke into ephilayo, kodwa ayinakubonwa ngeliso lomntu kwimeko yayo yendalo. Kolu vavanyo, sizahlula i-DNA yebhanana ukuze ibonakale.

Yintoni oya kuyidinga

Banana ibhanana exutywe

Ingxowa yeplastiki etywiniweyo

Indebe yeplastiki

Iitisipuni ezi-2 zesepha yokuhlamba izitya

1 tsp yetyuwa

Iipuniwe ezi-3 zamanzi acoliweyo

Isopropyl utywala

Iijagi ezi-2 ezincinci

Isefa okanye isihluzo

Umququzeleli okanye umthi weplanga

Ukuzahlula iDNA

Inyathelo 1. Thatha isingxobo seplastiki esitywiniweyo ubeke isiqingatha sebhanana engxoweni. Yongeza

I-3 tbsp yamanzi acoliweyo kwaye ubethe ibanana kude kube ngumushy (malunga nemizuzu emi-4 ukuya kwemihlanu). Beka utywala kwifriji ukuze ubande (ngokuzithandela).

Inyathelo 2. Lungisa isisombululo sokukhupha. Kwindebe yeplastiki, xuba i-2 tsp yesepha yokuhlamba izitya nge-1 tsp yetyuwa. Yongeza i-2 tbsp yamanzi adibeneyo. Gxotha ngobumnene ukuphepha ukudala i-foam. Qhubeka uvuselela imizuzu embalwa de isepha netyuwa inyibilike.

Inyathelo 3. Yongeza i-2 tsp ye-banana slush kwisisombululo sokukhupha kwaye unyakaze ngobunono ngomnye umzuzu.

Inyathelo 4. Phalaza umxube ngesisefo kwisitya esincinci ukuze ufumane isisombululo.

Inyathelo 5. Kwenye ingqayi, yongeza i-3 tsp ye-isopropyl alcohol. Kancinci kancinci, yongeza i-2 tsp yesisombululo sebhanana esixineneyo ukuze kubekho iindawo ezimbini zolwelo.

Inyathelo 6. Vumela ingqayi ihlale imizuzu emibini ukuya kwemithathu ngaphandle kokuphazamisa isisombululo. Uza kubona ifom ye-DNA ecacileyo okanye emhlophe kumaleko otywala. Ungayisusa i-DNA ngokusebenzisa i-skewer eyenziwe ngomthi kwaye uthabathe imitya usebenzisa isindululo esijikelezayo.

Inzululwazi

Nantsi into eyenzekileyo:

Imicu emide eshinyeneyo oyikhuphileyo kwisisombululo sokukhupha imisonto ye-DNA yebhanana.

I-DNA ikhona kwiseli nganye yezityalo nezilwanyana. Ipakishwe ngokuqinileyo ngaphakathi kwenucleus yeeseli. Inwebu yeseli kunye nenucleus zityebile kumafutha, ke sinako ukuzaphula ngokusebenzisa isepha yokuhlamba izitya. Ityuwa yongezwa ukwaqhekeza imixokelelwane yeeprotein ezibambe ii-nucleic acid kunye, zikhuphe iintambo ze-DNA.

I-DNA inyibilika emanzini kodwa hayi etywaleni. Ke xa sifaka utywala kwisisombululo sokukhupha, i-DNA iqokelela njengobunzima obumhlophe phezulu kwisisombululo.

Nwabisa iinyani zeDNA

Ubusazi ukuba…

Amawele afanayo aneDNA efanayo kuba aphuma kwiqanda elinye, elahlulahlula libe ziimbumba ezimbini emva kokuba lidityaniswe nedlozi. Bahlala bengabesini esinye kwaye bahlala benohlobo olufanayo lwegazi-nangona iminwe yabo ingohluka. Amawele angafani (amawele omzalwana) awanayo i-DNA efanayo.

Unokulinganisa ama-25,000 emicu ye-DNA ecaleni kwicala kububanzi bentloko enye yabantu abadala.

Singama-99.9 epesenti ngokufanayo. Ipesenti ye-0.1 yomahluko kwi-DNA isenza sahluke.

Umzali nomntwana babelana ngama-99.5 epesenti ye-DNA efanayo.

Sebenzisa iphephandaba

Njengokuba umntu ngamnye ene-DNA eyahlukileyo, wonke umntu unebali lakhe. Ngamanye amaxesha ibali lihlala umntu kwiphephandaba.

Jonga kwi-Enquirer kwaye usike imifanekiso yabantu abahlanu. Banokuba ziinkwenkwezi zemuvi, abezopolitiko, iimbaleki, nkqu nabantu abangadumanga kangako.

Ncamathelisa iifoto ephepheni.

Ngaphantsi komfanekiso ngamnye, bhala i-caption equka igama lomntu nokuba kutheni nganye isezindabeni namhlanje.
