Tib neeg muaj plaub yam rRNAs. Hloov RNA , los yog tRNA, txiav txim siab cov ntaub ntawv caj ces muaj nyob hauv lawvRNA thiab pab ntxiv cov amino acids rau cov saw hlau loj hlob. Cov kws tshawb fawb kwv yees tias tib neeg hlwb muaj ntau tshaj 500 txawv tRNAs.
Hais txog qhov no, puas yog RNA nyob hauv tib neeg?
Ntawm ntau hom RNA , peb qhov zoo tshaj plaws-paub thiab feem ntau kawm yog tub txib RNA (mRNA), hloov RNA (tRNA), thiab ribosomal RNA (rRNA), uas yog tam sim no nyob rau hauv tag nrho cov kab mob. Cov no thiab lwm yam ntawm RNAs Feem ntau ua cov tshuaj biochemical, zoo ib yam li cov enzymes.
Tsis tas li ntawd, RNA nyob qhov twg hauv tib neeg lub hlwb? Deoxyribonucleic Acid (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 feem ntau yog synthesized nyob rau hauv lub nucleus.
Qhov thib ob, tib neeg puas muaj RNA polymerase?
Tib neeg hlwb ua tau luam tsis tau xwb DNA , tab sis kuj RNA . Summary: Muaj cov mechanisms uas luam RNA rau hauv RNA , feem ntau txuam nrog ib qho enzyme hu ua RNA - nyob ntawm RNA polymerase , tsuas yog tau sau tseg hauv cov nroj tsuag thiab cov kab mob yooj yim, xws li cov poov xab, thiab cuam tshuam rau kev tswj hwm ntawm cov txheej txheem cellular tseem ceeb.
RNA yog dab tsi?
Ribonucleic acid ( RNA ) yog ib tug polymeric moleculees tseem ceeb nyob rau hauv ntau yam lom lub luag hauj lwm nyob rau hauv coding, decoding, kev cai thiab kev qhia ntawm noob. RNA thiab DNA yog nucleicacids, thiab, nrog rau lipids, proteins thiab carbohydrates, ua rau plaub loj macromolecules tseem ceeb rau txhua yam kev paub ntawm lub neej.

Puas yog Lavxias teb sab ntoo txiv ntseej muaj tshuaj lom rau tib neeg?
Close-up ntawm Lavxias teb sab txiv ntseej loj hlob ntawm tsob ntoo. Lavxias teb sab txiv ntseej (Elaeagnus angustifolia), uas loj hlob nyob rau hauv USDA zones 3 txog 7, yog ib tsob ntoo deciduous lossis loj shrub, nrog silvery nplooj thiab txiv hmab txiv ntoo uas zoo li txiv ntseej. Lavxias teb sab txiv ntseej tsis muaj tshuaj lom rau tsiaj thiab cov txiv hmab txiv ntoo yog txaus nyiam rau qee cov tsiaj qus
Puas yog beta particles muaj teeb meem rau tib neeg?
Ib qho beta particle yog li 8,000 npaug me dua li alpha particle - thiab qhov ntawd yog qhov ua rau lawv txaus ntshai. Lawv qhov me me tso cai rau lawv nkag mus rau khaub ncaws thiab tawv nqaij. Kev raug sab nraud tuaj yeem ua rau kub hnyiab thiab cov ntaub so ntswg puas, nrog rau lwm cov tsos mob ntawm kev mob hluav taws xob
Puas yog chimpanzees thiab tib neeg nyob hauv tib genus?
Tib neeg thiab chimpanzees yuav tsum tau muab tso rau hauv tib lub genus, Homo, raws li WSU cov kws tshawb fawb hauv tsab xov xwm Tsib Hlis 19 (#2172) luam tawm hauv Kev Ua Haujlwm ntawm National Academy of Sciences. Cov kev hloov pauv hauv qhov kev txiav txim thawj zaug tau ua rau muaj kev sib cav txog kev hloov pauv
Pine SAP puas muaj tshuaj lom rau tib neeg?
Pine Needle Risk rau tib neeg thiab tsiaj yug me nyuam, yug me nyuam qhov hnyav thiab lwm yam tshuaj lom neeg zoo sib xws yuav tshwm sim hauv tib neeg thiab tsiaj hauv tsev tom qab noj Pine koob. Txawm hais tias tib neeg feem ntau txaus siab rau Pine koob tshuaj yej uas tsis muaj kev mob tshwm sim, pineneedles tsis pom zoo siv los ntawm tib neeg thiab tsiaj
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
