Nucleotides hauv DNA muaj plaub txawv nitrogenous bases: Thymine, Cytosine, Adenine, los yog Guanine. Muaj ob pawg ntawm cov hauv paus: Pyrimidines: Cytosine thiab Thymine txhua muaj ib lub nplhaib rau tus tswv cuab.
Ntxiv mus, dab tsi ua rau nucleotides txawv ntawm ib leeg?
Lub xwb lwm yam qhov sib txawv hauv nucleotides DNA thiab RNA yog ib qho ntawm plaub lub hauv paus organic txawv nruab nrab ntawm ob lub polymers. Lub hauv paus adenine, guanine, thiab cytosine muaj nyob hauv DNA thiab RNA; thymine tsuas pom muaj nyob hauv DNA, thiab uracil tsuas pom muaj nyob hauv RNA xwb.
Ib tug kuj yuav nug, peb hom nucleotide yog dab tsi? A nucleotide yog ua los ntawm peb ntu : ib pawg phosphate, 5-carbon qab zib, thiab nitrogenous puag. Plaub lub hauv paus nitrogenous hauv DNA yog adenine, cytosine, guanine, thiab thymine. RNA muaj uracil, tsis yog thymine.
Xav txog qhov no, dab tsi ua rau txhua tus nucleotide tshwj xeeb?
Txawm tias nucleotides muab lawv cov npe los ntawm cov hauv paus nitrogenous uas lawv muaj, lawv tshuav ntau ntawm lawv cov qauv thiab muaj peev xwm sib txuas rau lawv cov deoxyribose molecule.
DNA nucleotide yog dab tsi?
Basic tsev thaiv ntawm DNA yog cov nucleotide . Cov nucleotide hauv DNA muaj cov suab thaj (deoxyribose), ib qho ntawm plaub lub hauv paus (cytosine (C), thymine (T), adenine (A), guanine (G)), thiab phosphate. Cytosine thiab thymine yog pyrimidine hauv paus, thaum adenine thiab guanine yog purine hauv paus.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
