DNA yog tsim los ntawm rau lub me me molecules - tsib carbon qab zib hu ua deoxyribose, phosphate molecule thiab plaub lub hauv paus sib txawv nitrogenous ( adenine , thymine , cytosine thiab guanine ).
Yog li ntawd, plaub nucleotides pom hauv DNA yog dab tsi?
Nucleotides hauv DNA muaj plaub sib txawv nitrogenous bases: Thymine, Cytosine, Adenine, los yog Guanine. Muaj ob pawg ntawm cov hauv paus: Pyrimidines: Cytosine thiab Thymine txhua tus muaj ib lub nplhaib rau tus tswv cuab.
Plaub nucleotides hauv RNA yog dab tsi? Plaub RNA puag yog adenine , ua uracil , guanine , thiab cytosine -feem ntau hu ua A, U, G, thiab C.
Tsuas yog li ntawd, qhov txawv ntawm plaub nucleotides uas ua rau DNA yog dab tsi?
Lwm tus xwb Qhov sib txawv ntawm nucleotides ntawm DNA thiab RNA yog qhov ntawd ntawm plaub organic bases txawv nruab nrab ob lub polymers. Cov hauv paus adenine, guanine, thiab cytosine tau pom hauv ob leeg DNA thiab RNA; thymine tsuas pom hauv DNA , thiab uracil tsuas pom hauv RNA.
Puas yog DNA ua los ntawm atoms?
Nws tsuas muaj ob peb hom atoms : carbon, hydrogen, oxygen, nitrogen, thiab phosphorus. Kev sib xyaw ntawm cov no atoms tsim cov qab zib-phosphate qaum ntawm lub DNA - ob sab ntawm tus ntaiv, hauv lwm lo lus. Lwm cov kev sib txuas ntawm cov atoms tsim plaub lub hauv paus: thymine (T), adenine (A), cytosine (C), thiab guanine (G).
