Kev txhais: mRNA rau protein Thaum lub sijhawm txhais lus, mRNA hloov mus rau cov protein. Ib pawg ntawm peb mRNA nucleotides encodes rau cov amino acid tshwj xeeb thiab hu ua codon. Txhua mRNA sib raug rau ib qho amino acid ib ntus thiab tsim cov protein ntau.
Y Yuav ua li cas yog cov proteins?
Cov Proteins Ua Li Cas? Lub tsev blocks ntawm cov proteins yog amino acids, uas yog cov organic molecules me me uas muaj cov alpha (central) carbon atom txuas mus rau ib pawg amino, pawg carboxyl, hydrogen atom, thiab a Cov khoom sib txawv hu ua ib sab saw (saib hauv qab).
Nucleotides tuaj qhov twg?
Nucleotides tau txais hauv kev noj haus thiab tseem synthesized los ntawm cov as-ham los ntawm lub siab Nucleotides yog tsim los ntawm peb subunit molecules: ib tug nucleobase, tsib-carbon qab zib (ribose los yog deoxyribose), thiab ib pawg phosphate muaj xws li ib tug mus rau peb phosphates.
Yuav ua li cas yog cov kauj ruam ntawm kev tsim cov protein?
Nws suav nrog peb kauj ruam: pib, elongation, thiab txiav tawm. Tom qab mRNA ua tiav, nws nqa cov lus qhia rau ribosome hauv cytoplasm. Kev txhais lus tshwm sim ntawm ribosome, uas muaj rRNA thiab cov proteins.
pom cov protein nyob qhov twg?
Protein pom thoob plaws hauv lub cev-hauv cov leeg nqaij, pob txha, tawv nqaij, plaub hau, thiab txhua yam ntawm lub cev lossis cov ntaub so ntswg. Nws ua rau cov enzymes uas muaj zog ntau cov tshuaj tiv thaiv thiab hemoglobin uas nqa oxygen hauv koj cov ntshav. Yam tsawg kawg 10,000 proteins sib txawv ua rau koj zoo li cas thiab ua rau koj li ntawd.

Nucleotides tsim nyob rau hauv lub cell nyob qhov twg?
Nucleotides tau txais hauv kev noj haus thiab tseem synthesized los ntawm cov as-ham los ntawm lub siabNucleotides yog tsim los ntawm peb subunit molecules: nucleobase, tsib-carbon qab zib (ribose los yog deoxyribose), thiab ib pawg phosphate uas muaj ib txog peb phosphates .
Nyob rau hauv nucleotides cov nitrogenous puag thiab pentose txuas los ntawm?
Muaj tsib lub hauv paus nitrogenous; adenine, guanine, thymine, cytosine thiab uracil. Nucleotides koom ua ke los ntawm covalent bonds ntawm pawg phosphate ntawm ib nucleotide thiab thib peb carbon atom ntawm pentose qab zibhauv nucleotide tom ntej .
Yuav ua li cas cov proteins tsim los ntawm cov amino acids?
Proteins yog tsim nyob rau hauv cov tshuaj tiv thaiv condensation thaum cov amino acid molecules koom ua ke thiab cov dej molecule raug tshem tawm. Daim ntawv cog lus tshiab tsim nyob rau hauv cov protein molecules uas cov amino acids tau koom nrog (-CONH) yog hu ua amide link lossis peptide link .
Puas yog tag nrho cov proteins tsim hauv cytosol?
Proteins txhua tus pib lawv cov synthesis hauv cytosol … Qee qhov tau ua tiav tag nrho hauv cytosol. Cov no tuaj yeem raug xa mus rau hauv mitochondrion, peroxisome, chloroplast, thiab nucleus ntawm kev thauj mus los tom qab kev txhais lus. Lwm cov proteins yog co-translationally imported rau hauv endoplasmic reticulum .
Puas yog feem ntau tsim los ntawm metamorphism ntawm cov xuab zeb?
Metamorphism ntawm quartz-nplua nuj sandstone tsim quartzite (Fig. 8.9), ib qho nyuaj heev, nonfoliated metamorphic pob zeb muaj yuav luag tag nrho ntawm silica. 2. Metamorphism ntawm limestone thiab dolomite ua rau recrystallization ntawm calcite los ua marble (Fig .
