Qhov sib txawv tseem ceeb ntawm qhov sib lawv liag thiab cov amino acid sib lawv liag yog qhov sib lawv liag yog cov nucleotide sib lawv liag ntawm DNA lossis RNA molecule, thaum cov amino acid sequence yog cov hlua ntawm cov amino acids txuas ua ke hauv peptide lossis cov protein..
DNA thiab RNA yog cov nucleic acids loj hauv cov kab mob muaj sia. DNA khaws cov ntaub ntawv keeb kwm ntawm ib lub cev. Yog li, feem ntau ntawm cov kab mob muaj sia muaj cov genomes tsim los ntawm DNA. Ib lub noob los yog ib qho tshwj xeeb nucleotide tawg ntawm chromosome encodes rau cov protein. Genetic code yog muab zais rau hauv nucleotide ib theem zuj zus ntawm cov noob. Thaum lub sij hawm gene qhia, lub hauv paus ib theem zuj zus transcribes thiab ces txhais mus rau hauv ib tug amino acid sequence ntawm ib tug protein.
Pib Sequence yog dab tsi?
Nucleotides yog lub tsev thaiv ntawm DNA thiab RNA. Deoxyribonucleotides ua DNA thaum ribonucleotides ua RNA. Txhua nucleotide muaj nitrogenous puag, pentose qab zib thiab ib pawg phosphate. Lub hauv paus yog qhov sib txawv ntawm plaub hom nucleotides. Yog li ntawd, nucleotides muaj npe raws li lub hauv paus. Nyob rau hauv lwm yam lus, lub hauv paus ib theem zuj zus ntawm ib tug nucleic acid sawv cev rau lub nucleotide ib theem zuj zus ntawm nws.
Daim duab 01: Lub hauv paus ib ntus
Feem ntau, cov kab ke hauv paus muaj cov ntaub ntawv keeb kwm ntawm lub cell. Cov nucleotide sequences tuaj yeem sau tau siv thawj tsab ntawv ntawm lub hauv paus ntawm nucleotides xws li adenine (A), thymine (T), guanine (G) thiab cytosine (C) hauv DNA sequences. Hauv RNA sequences, nucleotide sequences yog adenine (A), uracil (U), guanine (G) thiab cytosine (C)
Amino Acid Sequence yog dab tsi?
Ib qho amino acid sequence yog txoj hlua ntawm amino acids ntawm peptide los yog protein. Yog li, amino acids yog lub tsev blocks ntawm cov proteins. Amino acid sequence yog tsim los ntawm mRNA sequence. mRNA ib ntus pib los ntawm kev hloov pauv ntawm cov noob nyob rau hauv uas qhov kev txiav txim ntawm nucleotides hauv cov txheej txheem coding txiav txim siab qhov tshwm sim ntawm cov protein. Peb nucleotides sib sau ua ib codon, uas nyob rau hauv lem txiav txim lub amino acid. Yog li, txhua pawg ntawm peb DNA nucleotide hauv paus yog cov cai rau cov amino acid tshwj xeeb. Piv txwv li, DNA nucleotide puag ib ntus CTG cov lej rau cov amino acid leucine. Ib yam li ntawd, muaj 64 codons tau txiav txim siab nees nkaum amino acids. Thaum kawg, qhov tshwj xeeb amino acid ib ntus muab cov protein tshwj xeeb.
Daim duab 02: Amino Acid Sequence
Cov amino acid ib ntus yog qhov tseem ceeb uas txiav txim siab cov qauv thiab peb-dimensional zoo ntawm cov protein. Nws yog vim tias txhua tus amino acid muaj cov khoom tshwj xeeb uas txiav txim siab nws lub luag haujlwm hauv cov protein.
Dab tsi yog qhov zoo sib xws ntawm Base Sequence thiab Amino Acid Sequence?
- Base sequence thiab amino acid sequence yog cov hlua ntawm monomers ntawm DNA thiab protein, feem.
- Lub hauv paus ntawm DNA cov lej rau cov kab ke ntawm cov amino acids hauv cov saw hlau polypeptide, uas tsim cov protein.
- Kev ua pawg ntawm peb DNA nucleotide hauv paus ua rau cov codon tshwj xeeb uas cov lej rau cov amino acid tshwj xeeb.
Dab tsi yog qhov txawv ntawm Base Sequence thiab Amino Acid Sequence?
Base sequence yog txoj hlua ntawm nucleotides ntawm DNA lossis RNA thaum cov amino acid sequence yog cov hlua ntawm cov amino acids ntawm cov protein. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm qhov sib lawv liag thiab cov amino acid sequence. Tsis tas li ntawd, muaj plaub yam sib txawv ntawm nucleotides nyob rau hauv ib theem zuj zus, thaum muaj nees nkaum amino acids sib txawv nyob rau hauv ib tug amino acid sequence.
Ntxiv mus, qhov sib txawv ntxiv ntawm qhov sib lawv liag thiab cov amino acid sequences yog tias lub hauv paus sequences tuaj yeem muaj nyob ua ob txoj hlua khi, thaum cov amino sequences tsis muaj nyob ua ob-stranded.
Hauv qab infographic qhia ntau qhov sib txawv ntawm qhov sib lawv liag thiab amino acid ib ntus.
Summary – Base Sequence vs Amino Acid Sequence
Base sequence and amino acid sequence is two related sequences since the grouping of three nucleotides in base sequence codes for an amino acid. Yog li ntawd, lub hauv paus ib theem zuj zus yog ib theem zuj zus uas muaj cov noob caj noob ces ntawm cov amino acid sequence. Qhov tseeb, lub hauv paus kab ke yog monomer sequence ntawm DNA los yog RNA, thaum lub amino acid ib theem zuj zus yog monomer ib theem zuj zus ntawm ib tug protein. Yog li, qhov no qhia txog qhov sib txawv ntawm qhov sib lawv liag thiab cov amino acid sequence.
