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.
Dab tsi yog nitrogenous puag txuas rau hauv nucleotide?
Txhua nucleotide yog tsim los ntawm peb yam: nitrogenous puag, pentose (tsib-carbon) qab zib, thiab phosphate pawg (Daim duab 1). Txhua lub hauv paus nitrogenous hauv cov nucleotide yog txuas rau cov piam thaj molecule, uas txuas rau ib lossis ntau pawg phosphate.
Lub npe ntawm daim ntawv cog lus ntawm nitrogenous puag thiab pentose qab zib yog dab tsi?
Ob nucleotides txuas los ntawm kev sib txuas ntawm phosphodiester los tsim ib lub dinucleotide. Yog li, cov lus teb raug yog Kev Xaiv B (Glycosidic Bond) Ib daim ntawv cog lus glycosidic lossis glycosidic linkage yog ib hom kev cog lus cog lus uas koom nrog cov carbohydrate (qab zib) molecule rau ib pawg sib txawv, uas tuaj yeem lossis tsis tuaj yeem ua lwm yam carbohydrate.
Yuav ua li cas daim ntawv cog lus txuas mus rau pentose hauv nucleotide?
Txhua nucleotides muaj cov qauv sib xws: pawg phosphate txuas los ntawm a phosphoester daim ntawv cog lusrau pentose (tsib-carbon qab zib molecule) uas nyob rau hauv lem yog txuas mus rau ib tug organic puag. (Daim duab 4-1a).
Dab tsi txuas cov nitrogenous hauv paus rau ib leeg?
Lub hauv paus nitrogen yog tuav ua ke los ntawm hydrogen bonds: adenine thiab thymine tsim ob daim ntawv cog lus hydrogen; cytosine thiab guanine tsim peb daim ntawv cog lus hydrogen.

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 .
Dab tsi ntawm cov hauv qab no yog cov ntsiab lus ntawm kev sib txuas lus qauv ntawm de-escalation?
Lub Yim Hli Mloog. Kev mloog tso cai rau tus neeg npau taws "dej," uas yog txhais tau tias ua kom lub zog npau taws. … Acknowledge. Relaying tias koj nkag siab tias tus neeg lub ntsiab lus yog dab tsi los yog kev xav pab los ntawm kev lees paub lawv cov kev xav.
Puas txuas thiab txuas txuas yog tib yam?
Conjunctions grammatically koom nrog ob kab lus (ywj siab lossis kev vam, nyob ntawm qhov sib txuas) kom nws nyeem ua ib kab lus. Kev sib txuas yog siv ntawm ob kab lus sib cais. Muaj plaub hom kev sib txuas: kev sib koom ua ke, kev sib raug zoo, kev sib raug zoo, thiab kev sib txuas lus (sib tham lwm qhov) .
Puas tus neeg nyob hauv thiab cov neeg nyob ib puag ncig cuam tshuam?
Qhov tseeb, Cov Neeg Nyob thiab Transient orcas tuaj yeem pom nyob ze ze tab sis lawv yuav tsis koom nrog kev sib raug zoo. Kev noj zaub mov txawv yog qhov txawv ntawm ob hom orcas pom tawm ntawm ntug dej hiav txwv sab hnub poob ntawm Vancouver Island .
Qhov twg ntawm cov kuab tshuaj hauv qab no yog siv rau hauv kev sib txuas ntawm chlorofluorocarbon?
Dichloromethane yog ntau yam kev lag luam hnyav. Tus kws tshawb fawb Belgian Frédéric Swarts pioneer lub synthesis ntawm CFCs nyob rau hauv 1890s . CFCs ua li cas? CFCs thiab HCFCs feem ntau yog tsim los ntawm kev sib pauv halogen pib los ntawm chlorinated methanes thiab ethanesCov derivatives brominated yog tsim los ntawm cov tshuaj dawb-radical ntawm chlorofluorocarbons, hloov C-H daim ntawv cog lus nrog C- Br daim ntawv cog lus.
