Mloog cov lus. (bays payr) Ob lub hauv paus muaj nitrogen (los yog nucleotides) uas ua ke ua ke los tsim cov qauv ntawm DNA. Plaub lub hauv paus DNA yog adenine (A), cytosine (C), guanine (G), thiab thymine (T).
Puas muaj pes tsawg lub hauv paus hauv DNA?
Cov hauv paus yog adenine (A), thymine (T), guanine (G) thiab cytosine (C). Bases ntawm opposite strands khub tshwj xeeb; A ib txwm ua khub nrog T, thiab C ib txwm nrog G. Cov tib neeg genome muaj kwv yees li 3 billion ntawm cov hauv paus khub, uas nyob hauv 23 khub ntawm chromosomes hauv lub nucleus ntawm tag nrho peb cov hlwb.
Tus piv txwv piv txwv yog dab tsi?
Ib tug ntawm cov khub ntawm cov tshuaj hauv paus koom nrog hydrogen bonds uas txuas cov txuas ntxiv ntawm dna molecule los yog ntawm ib qho rna molecule uas muaj ob txoj hlua; Lub hauv paus khub yog adenine nrog thymine thiab guanine nrog cytosine hauv dna thiab adenine nrog uracil thiab guanine nrog cytosine hauv rna.…
3 lub hauv paus ntawm DNA yog dab tsi?
Tshwj tsis yog cov canonical puag khub "G-C" lossis guanine-cytosine, thiab "A-T" lossis adenine-thymine, Scripps Tshawb fawb cov kws tshawb fawb DNA muaj qhov thib peb khub: " 3FB-3FB " ntawm ob lub hauv paus tsis zoo hu ua 3-fluorobenzene (los yog 3FB).
RNA puag khub yog dab tsi?
RNA muaj plaub lub hauv paus nitrogenous: adenine, cytosine, uracil, thiab guanine. Uracil yog ib qho pyrimidine uas zoo ib yam li thymine, lwm pyrimidine uas pom hauv DNA. Zoo li thymine, uracil tuaj yeem ua khub nrog adenine (Daim duab 2).
