Cov ob DNA Cheebtsam uas yog qhia hauv Gizmo suav nrog phosphates thiab nucleosides.

Tsis tas li ntawd, dab tsi ua rau sab ntawm DNA molecule gizmo?

muaj ob ntu: - pentagonal qab zib (deoxyribose) thiab nitrogenous puag.

Ib yam li ntawd, muaj pes tsawg nitrogenous bases koj pom gizmo? plaub lub npe ntawm no nitrogenous bases yog adenine (liab), cytosine (daj), guanine (xiav), thiab thymine (ntsuab). Txoj Haujlwm A: Tsim kom muaj DNA moleculeGet the Gizmo npaj: ?Yog tias tsim nyog, nyem Resetto pib lub tsev txheej txheem.

Ib yam li ntawd, dab tsi yog cov rungs ntawm DNA ntaiv ua los ntawm?

Ob sab ntawm cov ntaiv yog ua los ntawm alternating qab zib thiab phosphate molecules. Cov piam thaj yog deoxyribose. Cov rungs ntawm ntaiv yog khub ntawm 4 hom nitrogen hauv paus. Ob lub hauv paus yog purines- adenine thiab guanine.

Koj pom pes tsawg nitrogenous bases?

Cov no yog qhov tseem ceeb planar, hydrophobic, tsis muaj zog hauv paus . Tsib nitrogenous bases muaj nyob rau hauv nucleic acids (Fig. 4); adenine (A), guanine (G), thiab cytosine (C) yog nyob rau hauv ob qho tib si DNA thiab RNA, whereas thymine (T) yuav luag tsuas muaj nyob rau hauv DNA, thiab uracil ( U ) yuav luag tshwj xeeb hauv RN A.
