Nyob rau hauv molecular biology thiab bioinformatics, qhov kev pom zoo ib ntus yog qhov kev txiav txim ntawm feem ntau cov residues, xws li nucleotide lossis amino acid, pom ntawm txhua txoj haujlwm hauv kev sib txuas ua ke.
txhais li cas los ntawm kev pom zoo ib ntus?
Ib qhov kev pom zoo yog ib ntu ntawm DNA, RNA, lossis cov protein uas sawv cev rau kev sib raug zoo, muaj feem cuam tshuam … uas sib haum rau thaj chaw khaws cia ntawm qhov tseem ceeb rau cov qauv thiab kev ua haujlwm.
