Lub eukaryotic cell yog ib lub cell uas muaj nws DNA nyob rau hauv ib tug txawv compartment ntawm lub cytoplasm ntawm lub cell vim yog ib tug membrane; DNA yog nyob rau hauv ib tug nucleus. Nucleus - Muaj DNA . Endoplasmic Reticulum - Muab faib ua ER (SER) thiab ntxhib ER (RER). Nws ua rau cov protein thiab lipids.
Kuj tseem paub yog, DNA puas muaj nyob hauv endoplasmic reticulum?
Cov nucleus, chloroplast thiab mitochondria. Nyob rau hauv cov tsiaj cell DNA raug txwv rau ob lub organelles vim lawv tsis muaj chloroplast. RNA yog pom nyob rau hauv lub nucleus, cytoplasm, Endoplasmic reticulum (cov mRNA uas encodes rau secretory proteins yog txuas nrog ER nto), mitochondria, chloroplast.
Tsis tas li ntawd, dab tsi organelles DNA tuaj yeem pom hauv? Peb lub organelles uas muaj DNA yog cov nucleus, mitochondria thiab chloroplasts . Organelles yog membrane-bound subunits nyob rau hauv ib lub cell - piv rau cov kabmob hauv lub cev - uas ua haujlwm tshwj xeeb. Lub nucleus yog qhov chaw tswj ntawm lub cell, thiab tsev cov ntaub ntawv genetic.
Ib sab saum toj no, cov organelles twg tsis muaj DNA?
Yog li yog tias peb tab tom hais txog cell organelles uas tsis muaj DNA, ces cov lus teb yog ER ( Endoplasmic Reticulum ). Teb: Lysosomes thiab Vacuoles tsis muaj DNA. Lysosomes yog bounded membrane organelles uas muaj nyob rau hauv lub hlwb ntawm cov tsiaj thiab nroj tsuag.
Puas yog txhua lub hlwb muaj DNA ua lawv cov khoom siv caj ces?
Eukaryotic cell muaj ib daim nyias nyias ntawm cov nucleus thiab ntau daim nyias nyias-pob organelles (piv txwv li, mitochondria, lysosomes, Golgi apparatus) tsis pom nyob rau hauv prokaryotes. Lub nucleus muaj feem ntau ntawm cov khoom siv caj ces ( DNA ) ntawm cell . Ntxiv DNA yog hauv mitochondria thiab (yog tias muaj) chloroplasts.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Puas yog HClO muaj zog lossis tsis muaj zog?
HClO yog ib qho kua qaub raws li nws muaj cov proton uas nws tso tawm tab sis nws yog ib qho tsis muaj zog acid vim nws tsis yog ib qho acidamoung cov npe ntawm cov kua qaub muaj zog
Puas yog NaCl muaj daim ntawv cog lus uas tsis muaj polar?
Yog lawm, NaCl yog ib daim ntawv cog lus ionic uas ua rau nws polar. Qhov txawv ntawm electronegativities yog dab tsi ua rau daim ntawv cog lus polar lossis nonpolar. Yog hais tias ob lub atoms nyob rau hauv ib daim ntawv cog lus muaj tib lub electronegativity, (xws li, uas muaj ob ntawm tib lub atoms) daim ntawv cog lus yog nonpolar vim tias ob lub atoms muaj qhov sib npaug ntawm cov electrons
Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
