Video: Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?

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.

Muaj pes tsawg lub vertices ib lub hauv paus puas Heptagonal prism muaj?
Teb thiab piav qhia: Lub heptagonal prism muaj 14 vertices. Ib tug heptagonal prism yog ib tug prism nyob rau hauv uas lub hauv paus yog heptagons, los yog polygons nrog xya sab thiab xya vertices
Puas yog lub hauv paus square ntawm 25 tus lej tag nrho?
Txij li thaum 25 yog tus lej ntuj thiab lub hauv paus square ntawm 25 yog tus naj npawb (5), 25 yog square zoo meej. 102.01 yog tus lej rational, thiab vim tias muaj lwm tus lej rational 10.1, xws li (10.1)2 = 102.01, 102.01 yog qhov zoo meej square
Puas yog tag nrho cov tshuaj nyob rau hauv ib chav kuaj pom tias muaj kev phom sij?
Tag nrho cov tshuaj nyob rau hauv lub chav kuaj yuav tsum raug xam tias yog txaus ntshai. 24. Muab tag nrho cov tshuaj uas tsis tau siv rov qab mus rau lawv cov ntim qub. Kev ua haujlwm hauv chav kuaj tuaj yeem pib tam sim ntawd thaum nkag mus rau hauv chav kuaj txawm tias tus kws qhia tseem tsis tau tuaj
Koj puas paub tias muaj pes tsawg lub orbitals nyob hauv lub plhaub?
Tus naj npawb ntawm orbitals nyob rau hauv ib lub plhaub yog cov square ntawm tus thawj quantum tooj: 12 = 1,22 = 4, 32 = 9. Muaj ib tug orbitalin ib tug subshell (l = 0), peb orbitals nyob rau hauv ap subshell (l = 1) , thiab tsib orbitals hauv ad subshell (l = 2). Yog li ntawd, tus naj npawb ntawm orbitals hauv subshell yog 2(l) +1
Muaj pes tsawg lub hauv paus ntev npaum li cas yog DNA ntawm ib lub cell?
Qhov no tso cai rau 3 billion lub hauv paus khub hauv txhua lub xov tooj kom haum rau hauv qhov chaw tsuas yog 6 microns thoob plaws. Yog tias koj ncab cov DNA hauv ib lub xovtooj ntawm txhua txoj kev tawm, nws yuav ntev li 2m thiab tag nrho cov DNA hauv koj lub hlwb muab tso ua ke yuav yog li ob npaug ntawm txoj kab uas hla ntawm lub Hnub Ci
