Yog li, muaj a tag nrho ntawm 25 + 25 = 50 aden thiab thymine hauv paus hauv tag nrho . Qhov ntawd nplooj 100 − 50 = 50 tshuav hauv paus . Nco tseg uas cytosine thiab guanine kev sib raug zoo nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Peb ua tau tam sim no faib los ntawm 2 kom tau tus lej ntawm guanine los yog cytosine hauv paus.

Ib yam li ntawd, pes tsawg nucleotides nyob hauv ib khub?

2 nucleotides

Ib yam li ntawd, qhov feem pua ntawm DNA hauv paus yog dab tsi? Vim koj paub tias muaj plaub xwb hauv paus hauv DNA ,cwb 4 hauv paus ua ke yuav tsum sib npaug 100 feem pua ntawm cov qauv. Yog tias muab cov ntaub ntawv hais tias tus qauv yog 20 feem pua guanine, koj tuaj yeem xav tias nws kuj yog 20 feem pua cytosine txij li guanine thiab cytosine khub ua ke. Ua ke, uas yog 40 feem pua ntawm tag nrho cov qauv.

Ntxiv rau qhov no, pes tsawg guanine hauv paus hauv DNA?

Guanine . Guanine (G) yog ib qho ntawm plaub yam tshuaj hauv paus hauv DNA , nrog rau lwm qhov peb yog adenine (A), cytosine (C), thiab thymine (T).

Vim li cas kev sib koom ua ke tseem ceeb?

Complementary pib ua khub yog tseem ceeb hauv DNA raws li nws tso cai rau puag khub yuav tsum tau teem nyob rau hauv feem ntau energetically haum txoj kev; Nws yog ib qho tseem ceeb hauv kev tsim cov qauv helical ntawm DNA. Nws kuj yog tseem ceeb nyob rau hauv replication raws li nws tso cai rau semiconservative replication.
