Qhov sib txawv tseem ceeb ntawm ribonucleotide thiab deoxyribonucleotide yog cov suab thaj ntawm txhua nucleotide. Ribose yog cov khoom qab zib ntawm ribonucleotides thaum deoxyribose yog cov suab thaj ntawm deoxyribonucleotide.
RNA thiab DNA yog cov polymers ntawm nucleotides; Lawv yog ribonucleotides thiab deoxyribonucleotides feem. Txawm hais tias txhua tus tib neeg zoo ib yam hauv kev nkag siab tias lawv muaj tib lub cev thiab cov khoom nruab nrog cev, peb txhua tus muaj qhov tshwj xeeb vim peb cov caj ces. Nws yog tus qauv DNA ntawm txhua tus neeg uas txiav txim siab nws lub cev thiab lub cev muaj pes tsawg leeg. DNA yog lub microscopic macromolecule uas khaws cov noob caj noob ces uas muab cov cim tshwj xeeb rau txhua tus neeg. RNA (ribonucleic acid) yog lwm qhov ntawm peb lub macromolecules loj (nrog rau cov proteins thiab DNA) uas yog ib qho tseem ceeb rau peb lub neej.
Ribonucleotide yog dab tsi?
Ib ribonucleotide yog lub tsev thaiv ntawm RNA. Nws muaj peb yam xws li ribose qab zib, nitrogenous puag, thiab phosphate pawg. Ntxiv mus, nws muaj ib pawg OH nyob rau hauv lub nplhaib pentose qab zib, ntawm 2 'carbon atom. Nitrogenous hauv paus ntawm ribonucleotides yog Adenine, Guanine, Cytosine, thiab Uracil.
Daim duab 01: Ribonucleotide
Hauv qhov sib piv rau cov chav hauv paus ntawm DNA, ribonucleotides muab lwm yam kev ua haujlwm ntawm tes xws li kev tswj hwm ntawm tes thiab kev taw qhia ntawm tes. Tsis tas li ntawd, ribonucleotides tuaj yeem hloov mus rau ATP lossis Cyclic AMP.
Dab tsi yog Deoxyribonucleotide?
A deoxyribonucleotide yog lub tsev thaiv ntawm DNA. Hauv feem ntau cov kab mob muaj sia, DNA ua haujlwm raws li cov khoom siv caj ces uas muaj cov ntaub ntawv caj ces. Yog li, DNA yog suav tias yog qhov tseem ceeb tshaj plaws macromolecule hauv lub cev.
Daim duab 02: Deoxyribose
Deoxyribonucleotide txawv ntawm ribonucleotide vim muaj qee yam. Nws muaj deoxyribose qab zib es tsis txhob ribose qab zib. Ntxiv mus, deoxyribonucleotide muaj thymine es tsis txhob ntawm uracil li hauv RNA. Ribose thiab deoxyribose qab zib molecules sib txawv ntawm ib leeg los ntawm qhov sib txawv ntawm 2' carbon atom. Ribonucleotide muaj OH hauv 2' Carbon thaum deoxyribonucleotide muaj H atom hauv 2' Carbon.
Dab tsi yog qhov zoo sib xws ntawm Ribonucleotide thiab Deoxyribonucleotide?
- Ribonucleotide thiab Deoxyribonucleotide yog nucleotides thiab monomers ntawm RNA thiab DNA, feem.
- Ob leeg muaj peb yam: puag, pentose qab zib, thiab ib pawg phosphate.
- Tsis tas li, ob qho tib si daim ntawv cog lus phosphodiester los ntawm 3′-5′ kom txuas nrog lwm cov nucleotide.
- Tsis tas li ntawd, ob qho tib si nucleotides muaj peb lub hauv paus nitrogenous xws li Adenine, Guanine, thiab Cytosine.
Qhov txawv ntawm Ribonucleotide thiab Deoxyribonucleotide yog dab tsi?
RNA yog tsim los ntawm ribonucleotides thaum DNA yog tsim los ntawm deoxyribonucleotides. Qhov sib txawv tseem ceeb ntawm ribonucleotide thiab deoxyribonucleotide yog pentose qab zib. Ribose yog cov khoom qab zib ntawm ribonucleotide thaum deoxyribose yog cov suab thaj ntawm deoxyribonucleotide. Tsis tas li ntawd, lwm qhov sib txawv ntawm ribonucleotide thiab deoxyribonucleotide yog nyob rau hauv lub hauv paus nitrogenous. Ribonucleotides muaj uracil es tsis txhob ntawm thymine hauv deoxyribonucleotides. Tsis tas li ntawd, Ribonucleotide muaj OH hauv 2' Carbon thaum deoxyribonucleotide muaj H atom hauv 2' Carbon.
Cov duab hauv qab no qhia qhov sib txawv ntawm ribonucleotide thiab deoxyribonucleotide hauv daim ntawv.
Summary – Ribonucleotide vs Deoxyribonucleotide
Ob DNA thiab RNA zoo ib yam thiab ua haujlwm zoo sib xws. Txawm li cas los xij, muaj qhov sib txawv me me ntawm ribonucleotide thiab deoxyribonucleotide, uas ua rau lawv ua haujlwm sib txawv. Ribonucleotide muaj ribose ua cov suab thaj thaum deoxyribose yog cov suab thaj ntawm deoxyribonucleotide.
