Ribonucleotide yog hais txog ib qho nucleotide uas muaj ribose thiab tshwm sim tshwj xeeb tshaj yog ib qho tseem ceeb ntawm RNA thaum deoxyribonucleotide hais txog nucleotide uas muaj deoxyribosethiab yog ib feem ntawm DNA.
Qhov txawv ntawm nucleotide thiab deoxyribonucleotide yog dab tsi?
Nucleotides yog tsim los ntawm phosphoric acid, pentose qab zib (ribose los yog deoxyribose), thiab muaj nitrogen-muaj puag (adenine, cytosine, guanine, thymine, los yog uracil). Ribonucleotides muaj ribose, thaum deoxyribonucleotides muaj deoxyribose.
Dab tsi ua rau nucleotide txawv ntawm lwm cov nucleotides?
Cov ntsiab lus hauv cov txheej no (9)
Yuav ua li cas ib qho nucleotide txawv ntawm lwm tus? Txhua nucleotides muaj nitrogen hauv paus thiab txhua nucleotide muaj nitrogen sib txawv. Rau RNA, koj tsis pom thylosine koj tsuas pom Uracil.
Dab tsi yog qhov txawv ntawm deoxyribonucleotide thiab Deoxyribonucleoside?
A deoxyribonucleotide muaj ib pab pawg hydroxyl (OH) ntawm txoj haujlwm 3' ntawm cov suab thaj ribose tab sis tsis muaj oxygen ntawm cov pa roj carbon thib ob vim li no hu ua deoxyribonucleotide. Ib qho Dideoxyribonucleotide hloov pauv yuav tsuas muaj hydrogen (H) ntawm txoj hauj lwm 3'. Yog li nws tsis muaj ob lub pa oxygen yog li hu ua Dideoxy.
YPuas yog ribonucleotide yog Pyranose?
a deoxyribonucleotide muaj β configuration; ribonucleotide muaj β configuration ntawmC-1. … E) ribonucleotide yog ib qho pyranose, deoxyribonucleotide yog furanose. Qhov txawv ntawm ib tug ribonucleotide thiab ib tug deoxyribonucleotide yog: A) ib tug deoxyribonucleotide muaj ib tug -H es tsis txhob ntawm ib tug -OH ntawm C-2.
