DNA yog ib tug ntev polymer nrog deoxyriboses thiab phosphate qaum. Muaj plaub txawv nitrogenous bases: adenine, guanine, cytosine thiab thymine. RNA yog ib tug polymer nrog ib tug ribose thiab phosphate qaum. Plaub txawv nitrogenous bases: adenine, guanine, cytosine, anduracil.
Hais txog qhov no, qhov txawv ntawm DNA thiab RNA extraction yog dab tsi?
Lub ntsiab Qhov sib txawv ntawm DNA thiab RNAextraction yog qhov pH theem ntawm DNA rho tawm yog pH8 hos pH theem RNA rho tawm yog pH 4.7. DNA thiab RNA extraction yog ob txoj kev koom tes hauv kev cais tawm thiab ua kom huv ntawm nucleic acids los ntawm cov cell ntawm cov ntaub so ntswg. Ob txheej txheem muaj peb kauj ruam.
Tsis tas li ntawd, lub hauv paus ntawm DNA thiab RNA yog dab tsi? Hauv DNA , muaj plaub qhov sib txawv hauv paus : adenine (A) thiab guanine (G) yog cov purines loj dua. Cytosine (C) thiab thymine (T) yog cov pyrimidines me. RNA kuj muaj plaub qhov sib txawv hauv paus . Peb ntawm no yog tib yam nyob rau hauv DNA : adenine, guanine, thiab cytosine.
Ntxiv mus, RNA yog dab tsi thiab nws txawv ntawm DNA li cas?
DNA stands rau deoxyribonucleic acid, thaum RNA sawv cev rau ribonucleic acid. DNA , yog li, nqa adeoxyribose qab zib thiab RNA muaj ribose qab zib. DNA yog tsim los ntawm ntau hom nitrogenous hauv paus: adenine, thymine, cytosine thiab guanine. RNA muaj nitrogenous bases zoo ib yam li DNA , tab sis tsis muaj thymine.
Lub luag haujlwm ntawm mRNA yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm mRNA yog los ua tus neeg nruab nrab ntawm cov ntaub ntawv caj ces hauv DNA thiab cov aminoacid qib ntawm cov protein. mRNA muaj cov codons uas yog ua tiav rau qhov sib lawv liag ntawm nucleotides ntawm tus qauv DNA thiab coj tus tsim cov amino acids los ntawm kev ua ntawm ribosomes thiab tRNA.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
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
