DNA sawv rau deoxyribonucleic acid , thaum RNA yog ribonucleic acid. Txawm hais tias DNA thiab RNA ob leeg muaj cov ntaub ntawv caj ces, muaj qee qhov sib txawv ntawm lawv.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog lub ntsiab lus ntawm DNA thiab RNA?
Ob yam tseem ceeb ntawm nucleic acids yog DNA thiab RNA . Ob leeg DNA thiab RNA yog tsim los ntawm nucleotides, txhua tus muaj tsib-carbon qab zib qaum, ib pawg phosphate, thiab nitrogen hauv paus. DNA muab cov cai rau lub cell cov dej num, thaum RNA converts cov cai ntawd rau hauv cov protein kom ua haujlwm ntawm tes.
Ib sab saum toj no, vim li cas DNA thiab RNA tseem ceeb? Deoxyribonucleic acid ( DNA thiab ribonucleic acid ( RNA ) tej zaum yog feem ntau tseem ceeb molecules nyob rau hauv cell biology, lub luag hauj lwm rau kev cia thiab nyeem cov ntaub ntawv ntawm caj ces uas underpins tag nrho lub neej. Cov kev sib txawv no ua rau ob lub molecules ua haujlwm ua ke thiab ua tiav lawv lub luag haujlwm tseem ceeb.
Tsis tas li ntawd, DNA thiab RNA nyob qhov twg?
Muaj ob hom nucleic acids uas yog polymers pom nyob rau hauv tag nrho cov muaj sia nyob. Deoxyribonucleic acid (nrog rau DNA ) yog pom Feem ntau nyob rau hauv lub nucleus ntawm lub cell, thaum Ribonucleic acid ( RNA ) yog pom Feem ntau nyob rau hauv lub cytoplasm ntawm lub cell txawm hais tias nws yog feem ntau synthesized nyob rau hauv lub nucleus.
Tus qauv ntawm DNA thiab RNA yog dab tsi?
Lawv yog tsim los ntawm monomers, uas yog nucleotides ua los ntawm peb yam: ib tug 5-carbon qab zib, ib pawg phosphate thiab ib tug nitrogenous puag. Yog hais tias cov piam thaj yog ib qho yooj yim ribose, lub polymer yog RNA (ribonucleic acid); Yog hais tias cov piam thaj yog muab los ntawm ribose li deoxyribose, lub polymer yog DNA (deoxyribonucleic acid).
Pom zoo:
Puas yog beryllium yog hlau lossis nonmetal lossis metalloid?
Beryllium yog hlau. Nws yog nyob rau hauv alkaline ntiaj teb hlau pawg nyob rau hauv lub periodic lub rooj thiab muaj tshuaj thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj ib tug ntau dua melting point tshaj ob qho tib si
Dab tsi yog qhov xwm txheej yog nws txuas ntxiv lossis ntu?
Cov teeb meem tsis tas mus li thiab yog ib feem ntawm qhov xwm txheej, piv txwv li nws yog tsim los ntawm cov khoom
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Dab tsi muaj DNA tab sis tsis yog cytoplasm lossis ribosomes?
Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Prokaryotic Cells. Prokaryotic Cells Eukaryotic Cells Nucleus Tsis Yog DNA Ib daim duab ntawm DNA Ntau cov chromosomes Membrane-Bound Organelles Tsis Yog Piv txwv Cov Kab Mob Nroj Tsuag, tsiaj txhu, fungi
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
