DNA hauv prokaryotes muaj nyob hauv thaj chaw nruab nrab ntawm lub xovtooj hu ua nucleoid nucleoid Lub nucleoid (lub ntsiab lus nucleus zoo li) yog thaj tsam tsis xwm yeem nyob rau hauv lub cell prokaryotic uas muaj tag nrho lossis feem ntau ntawm cov khoom siv caj ces. … Nyob rau hauv sib piv rau lub nucleus ntawm ib tug eukaryotic cell, nws tsis yog surrounded los ntawm ib tug nuclear membrane. https://en.wikipedia.org › wiki › Nucleoid
Nucleoid - Wikipedia
, uas tsis nyob ib puag ncig los ntawm cov kab hluav taws xob nuclear. Ntau tus prokaryotes tseem nqa me me, ncig DNA molecules hu ua plasmids, uas txawv ntawm chromosomal DNA thiab tuaj yeem muab cov txiaj ntsig zoo hauv cov cheeb tsam tshwj xeeb.
Puas noob muaj nyob hauv prokaryotes?
Cov noob tau teeb tsa ua ke hauv pawg hu ua lac operon Lub koom haum ntawm prokaryotic DNA yog li txawv ntawm cov eukaryotes hauv ntau txoj hauv kev tseem ceeb. Qhov sib txawv tseem ceeb tshaj plaws yog cov txheej txheem condensation uas prokaryotic DNA molecules tau nkag mus kom haum rau hauv cov hlwb me me.
Cov noob nyob qhov twg hauv cov kab mob?
Cov kab mob kab mob nyob nyob rau hauv lub cytoplasm ntawm ib tug supercoiled chromosomenrog rau ntawm extrachromosomal plasmids.
Cov khoom siv caj ces nyob qhov twg hauv lub cell eukaryotic?
Nyob rau hauv eukaryotes, lub xovtooj ntawm cov khoom siv caj ces, lossis DNA, muaj nyob rau hauv ib lub organelle hu ua nucleus, qhov uas nws tau teeb tsa hauv cov molecules ntev hu ua chromosomes.
DNA sawv cev rau dab tsi ?
Teb: Deoxyribonucleic acid - ib qho loj molecule ntawm nucleic acid pom nyob rau hauv lub nuclei, feem ntau nyob rau hauv chromosomes, ntawm cov hlwb nyob. DNA tswj cov haujlwm xws li kev tsim cov protein molecules hauv lub cell, thiab nqa cov qauv rau kev yug me nyuam ntawm txhua tus yam ntxwv ntawm nws cov hom tshwj xeeb.

Nucleotides tsim nyob rau hauv lub cell nyob qhov twg?
Nucleotides tau txais hauv kev noj haus thiab tseem synthesized los ntawm cov as-ham los ntawm lub siabNucleotides yog tsim los ntawm peb subunit molecules: nucleobase, tsib-carbon qab zib (ribose los yog deoxyribose), thiab ib pawg phosphate uas muaj ib txog peb phosphates .
Noob noob noob noob yog dab tsi?
A monogerm noob muaj ib lub embryo nkaus xwbCov txiv hmab txiv ntoo ntawm qee cov nroj tsuag (xws li beet qab zib) feem ntau siv rau kev nthuav tawm thiab feem ntau nws muaj ntau yam noob. Txawm li cas los xij, cov txiv hmab txiv ntoo no tuaj yeem hloov kho cov noob caj noob ces kom muaj ib lub noob los yog cov khoom tawg yooj yim los ua monogerm .
Cov noob caj noob ces nyob qhov twg?
Kev txhais yuav siv qhov chaw hauv lub nucleus. Nws siv DNA ua tus qauv los ua ib qho RNA (mRNA) molecule. Thaum lub sij hawm transcription, ib tug strand ntawm mRNA yog ua uas yog complementary rau ib tug strand ntawm DNA. Daim duab 1 qhia tias qhov no tshwm sim li cas .
Qhov chaw ntawm cov pob txha zoo li lub ntsej muag nyob rau hauv tib neeg lub cev nyob qhov twg?
Qhov chaw ntawm cov pob txha zoo li lub ntsej muag nyob rau hauv tib neeg lub cev nyob qhov twg? Cov pob txha 'lunate' yog qhov txawv ntawm nws qhov sib sib zog nqus concavity thiab crescentic qauv. Nws nyob nyob rau hauv kab sib thooj ntawm carpals ntawm lub lateral 'scaphoid' thiab medial 'triquetral triquetral Lub triquetral pob txha (/traɪˈkwɛtrəl, -ˈkwiː-/;
Feem ntau ntawm atp nyob qhov twg hauv cov hlwb prokaryotic?
ATP yog tsim nyob rau hauv plasma membranentawm cov hlwb prokaryotic. ATP yog lub ntsiab lub zog cia molecule pom nyob rau hauv hlwb . ATP tsim nyob rau hauv cov hlwb prokaryotic nyob qhov twg? Mitochondria, piv txwv li, yog cov organelles uas muab eukaryotes nrog rau feem ntau ntawm lawv lub zog los ntawm kev tsim lub zog nplua nuj molecules hu ua ATP.
