Francis Crick, yog ib qho ntawm cov codiscoverers ntawm peb-dimensional ob helical qauv ntawm DNA, yog ib tug thawj coj hais tias ib tug gene yog ib tug linear sequence ntawm nucleotides ib theem zuj zus ntawm nucleotides Vim tias muaj plaub lub hauv paus tshwm sim nitrogenous, muaj plaub hom DNA nucleotides: adenine (A), thymine (T), guanine (G), thiab cytosine (C) … Raws li DNA polymerase txav mus rau hauv ib leeg-stranded DNA, nws siv qhov sib lawv liag ntawm nucleotides nyob rau hauv cov strand raws li ib tug qauv rau replication. https://www.nature.com › scitable › topicpage › the-order-of-…
Kev txiav txim ntawm Nucleotides hauv cov noob tau nthuav tawm los ntawm DNA Sequencing
thiab tias txhua tus noob encoded ib leeg protein.
Dab tsi ntawm genome encodes rau protein?
A noob yog ib txoj hlua ntawm DNA uas encodes cov ntaub ntawv tsim nyog los ua cov protein, uas tom qab ntawd mus ua qee yam haujlwm hauv peb lub hlwb.
Dab tsi encodes proteins nyob rau hauv ib lub cell?
A noob yog ib qho kev txiav txim ntawm nucleotides nyob rau ntawm ib txoj hauj lwm ntawm ib qho chromosome uas encodes ib qho kev ua haujlwm protein. Lub hauv paus tseem ceeb ntawm kev tsim noob neej uas nqa cov ntaub ntawv caj ces los ntawm ib tiam mus rau lwm tiam.
Yuav ua li cas cov noob code rau ib leeg protein?
Txhua cov protein yog coded los ntawm ib ntu ntawm DNA hu ua noob… Ua ke, kev sau thiab txhais lus yog hu ua gene expression. Thaum tus txheej txheem ntawm transcription, cov ntaub ntawv khaws cia nyob rau hauv ib tug noob DNA yog pauv mus rau ib tug zoo xws li molecule hu ua RNA (ribonucleic acid) nyob rau hauv lub cell nucleus.
Puas yog protein encoded los ntawm DNA?
Cov txheej txheem ntawm kev txhais lus tuaj yeem pom raws li kev txiav txim siab ntawm cov lus qhia ua cov protein, koom nrog mRNA hauv kev sau ntawv thiab tRNA. Cov noob hauv DNA encode protein molecules, uas yog "cov neeg ua haujlwm" ntawm tes, ua txhua yam haujlwm tsim nyog rau lub neej.

Puas yog lub tsev nyob ib lub tsev?
Yog koj nyob hauv tsev, nws yog koj lub tsev, tab sis nws tsis yog tsev. Qhov ntawd yog ib qho tseem ceeb sib txawv, tshwj xeeb tshaj yog thaum nws los txog rau kev tu. Xav txog yog tias koj muaj ib lub tsev nyob ib leeg thiab lub ru tsev yuav tsum tau kho .
Keck kawm tiav lub tsev kawm ntawv puas yog lub tsev kawm zoo?
Keck Graduate Institute yeej mob siab txog koj txoj kev vam meej. Nws yog qhov kev hloov pauv zoo los ntawm UC system uas koj tsuas yog tus lej suav, thiab kuv zoo siab pom tias yav tom ntej yuav muaj dab tsi. KGI muaj qhov chaw kawm zoo nrog lub zej zog muaj zog vim muaj kev txhawb nqa cov neeg ua haujlwm, kws qhia ntawv, thiab cov tub ntxhais kawm .
Puas yog lub tsev lossis lub tsev?
Lub npe townhouse lossis lub tsev nyob tom qab tau siv los piav qhia cov chav tsis sib xws hauv cov cheeb tsam suburban uas tsim los ua cov tsev sib cais lossis ib nrab tsev. Niaj hnub no, lo lus townhouse yog siv los piav txog cov chav nyob ua ke ib lub tsev uas txuas nrog hauv ntau chav tsev.
Thaum twg ib qho hluav taws xob thiab ib qho hluav taws xob sib tsoo lawv?
Thaum ib qho hluav taws xob thiab positron (antielectron) sib tsoo ntawm lub zog siab, lawv tuaj yeem rhuav tshem los tsim cov quarks ntxim nyiam uas tom qab ntawd tsim D + thiab D - mesons . Yuav ua li cas thaum photons sib tsoo?
Lub tsev kawm ntawv twg yog lub tsev kawm ntawv stuart?
Biography. Stuart Hall tau yug los rau 3 Lub Ob Hlis 1932 hauv Kingston, Jamaica, rau hauv tsev neeg Jamaican nruab nrab ntawm African, Lus Askiv, Neeg Yudais Portuguese, thiab zoo li Indian qhovntsej thiaj tsis mob. Nws tau mus kawm Jamaica College, tau txais kev kawm ua qauv tom qab lub tsev kawm ntawv Askiv .
