Muaj plaubDNA nucleotides, txhua tus muaj ib qho ntawm plaub lub hauv paus nitrogen (adenine, thymine, cytosine, thiab guanine). Thawj tsab ntawv ntawm txhua ntawm plaub lub hauv paus no feem ntau yog siv los ua lub cim ntawm cov nucleotide (A rau adenine nucleotide, piv txwv li). DNA tsim ib tug ob-stranded kauv, los yog ob helix.
Muaj pes tsawg Cytosines?
Muaj four sib txawv nucleotides uas tsim cov polymer ntawm DNA: thymine, cytosine, adenine, thiab guanine. Plaub nucleotides no muaj nyob rau hauv ob chav sib txawv raws li cov qauv.
Muaj pes tsawg Adenines nyob rau hauv ob lub helix?
Ob chav Helix
A DNA molecule muaj ob txoj hlua uas cua ncig ib leeg zoo li tus ntaiv twisted. Txhua strand muaj lub nraub qaum ua los ntawm cov pab pawg suab thaj (deoxyribose) thiab phosphate pawg. Txuas rau txhua lub suab thaj yog ib qho ntawm plaub hauv paus: adenine (A), cytosine (C), guanine (G), lossis thymine (T).
Puas muaj pes tsawg thymine bases?
Thymine. Thymine (T) yog ib qho ntawm plaub tshuaj hauv DNA, lwm qhov peb yog adenine (A), cytosine (C), thiab guanine (G). Nyob rau hauv DNA molecule, thymine bases nyob rau ntawm ib tug strand tsim tshuaj bonds nrog adenine bases ntawm opposite strand. Qhov sib lawv liag ntawm plaub DNA hauv paus encodes lub xovtooj ntawm cov lus qhia caj ces…
Muaj pes tsawg adenine bases muaj?
Adenine. Adenine (A) yog ib qho ntawm plaub tshuaj hauv DNA, nrog rau lwm qhov peb yog cytosine(C), guanine (G), thiab thymine (T).
