Qhov sib txawv tseem ceeb ntawm deoxyribonucleic acid thiab ribonucleic acid yog tias monomer ntawm deoxyribonucleic acid yog deoxyribonucleotide thaum monomer ntawm ribonucleic acid yog ribonucleotide. Lwm qhov sib txawv tseem ceeb ntawm deoxyribonucleic acid thiab ribonucleic acid yog tias deoxyribonucleic acid yog ob-stranded thaum ribonucleic acid yog ib leeg-stranded.
Deoxyribonucleic acid (DNA) thiab ribonucleic acid (RNA) yog ob hom nucleic acids. DNA khaws cov ntaub ntawv keeb kwm ntawm feem ntau cov kab mob nyob. Txawm li cas los xij, qee cov kab mob muaj RNA genomes. Lawv yog cov polymers tsim los ntawm nucleotide monomers.
Deoxyribonucleic Acid yog dab tsi?
Deoxyribonucleic acid (DNA) yog ib qho tseem ceeb nucleic acid hauv cov kab mob muaj sia. Nws khaws cov ntaub ntawv ntawm caj ces. Deoxyribonucleotides yog lub hauv paus ntawm DNA. Muaj peb yam khoom nyob rau hauv ib tug deoxyribonucleotide uas yog, deoxyribose qab zib, phosphate pawg thiab nitrogenous puag. Nitrogenous bases tsim hydrogen bonds thiab stabilize lub ob-stranded DNA. Li no, DNA yog ib qho polymer ruaj khov nrog lub neej ntev.
Daim duab 01: DNA
Txawm li cas los xij, DNA muaj kev cuam tshuam ntau dua rau UV kev puas tsuaj. Cov nucleic acid no nyob hauv lub nucleus thiab tsis tuaj yeem tawm hauv lub nucleus, tsis zoo li RNA. Qee qhov DNA muaj nyob hauv mitochondria ib yam nkaus.
Ribonucleic Acid yog dab tsi?
Ribonucleic acid (RNA) yog hom thib ob ntawm nucleic acid tam sim no hauv cov kab mob muaj sia. Muaj peb hom RNA: mRNA, tRNA, thiab rRNA. RNA tsim nyob rau hauv lub nucleus. Txawm li cas los xij, lawv tawm hauv lub nucleus thiab tom qab ntawd txav mus rau hauv cytoplasm. Qee qhov txuas nrog ribosomes thiab pab hauv kev tsim cov protein.
Daim duab 02: DNA vs RNA
RNA suav nrog ribonucleotides. Ribonucleotide muaj ribose qab zib, nitrogenous puag, thiab phosphate pawg. RNA tsis muaj thymine puag. Nws muaj uracil thiab lwm yam peb lub hauv paus: adenine, guanine, thiab cytosine. RNA feem ntau yog ib leeg-stranded thiab nws tsis tshua muaj kev puas tsuaj rau UV, tsis zoo li DNA. Tsis tas li ntawd, nws muaj lub neej luv luv thiab yog luv luv polymer.
Dab tsi zoo sib xws ntawm Deoxyribonucleic Acid thiab Ribonucleic Acid?
- Deoxyribonucleic acid thiab ribonucleic acid yog nucleic acids.
- Ob leeg muaj phosphate pawg thiab pentose qab zib.
- Lawv muaj nitrogenous hauv paus.
- Ob leeg yog cov molecules tseem ceeb hauv cov kab mob nyob.
- Ob lub molecules tseem ceeb rau kev khaws cia thiab nyeem cov ntaub ntawv caj ces ntawm cov kab mob.
- YLawv yog cov polymers.
Qhov txawv ntawm Deoxyribonucleic Acid thiab Ribonucleic Acid yog dab tsi?
Deoxyribonucleic acid lossis DNA yog nucleic acid uas khaws cov ntaub ntawv caj ces ntawm cov kab mob nyob. Ribonucleic acid los yog RNA yog lwm cov nucleic acid uas tau hloov mus rau hauv cov amino acid sib lawv liag thaum lub sij hawm cov protein synthesis. Tsis tas li ntawd, DNA yog ob zaug tso tseg thaum RNA yog ib leeg tso tseg. DNA muaj lub neej ntev thiab ruaj khov dua RNA. DNA muaj plaub lub hauv paus nitrogen: adenine, guanine, thymine, thiab cytosine. Tab sis RNA tsis muaj thymine puag. Nws muaj uracil puag xwb.
Ntxiv mus, DNA muaj nyob rau hauv lub nucleus thiab mitochondria thaum RNA muaj nyob rau hauv lub cytoplasm. DNA cov ntsiab lus nyob rau hauv ib lub cell yog tsau. Tab sis cov ntsiab lus RNA muaj qhov sib txawv. RNA kuj tiv taus UV ntau dua piv rau DNA.
Summary – Deoxyribonucleic Acid vs Ribonucleic Acid
DNA thiab RNA yog ob lub nucleic acid polymers. Khaws cov ntaub ntawv caj ces yog qhov tseem ceeb ntawm DNA thaum hloov mus rau hauv cov amino acid sib lawv liag yog qhov tseem ceeb ntawm RNA. Tsis tas li ntawd, DNA yog ob zaug tso tseg thaum RNA ib leeg tso tseg. Qhov no yog qhov txawv ntawm DNA thiab RNA.
