Lub ribosome yog ib qho nyuaj molecule ua los ntawm ribosomal RNA molecules thiab cov proteins uas tsim lub Hoobkas rau cov protein synthesis hauv hlwb. Xyoo 1955, George E. Palade nrhiav pom ribosomes thiab piav qhia lawv li cov khoom me me hauv cytoplasm uas nyiam cuam tshuam nrog endoplasmic reticulum membrane.
Leej twg nrhiav tau rRNA?
Severo Ochoa yeej xyoo 1959 Nobel nqi zog hauv tshuaj tom qab nws tshawb pom tias RNA yog li cas. Qhov sib lawv liag ntawm 77 nucleotides ntawm poov xab tRNA tau pom los ntawm Robert W. Holley xyoo 1965. Holley yeej 1968 Nobel nqi zog hauv tshuaj rau nws txoj kev tshawb fawb.
Leej twg yog tus thawj tus pom ribosome?
Discovery. Ribosomes tau pom thawj zaug hauv nruab nrab-1960s los ntawm Romanian-American cell biologist George Emil Palade, siv lub tshuab ntsuas hluav taws xob, ua cov khoom ntom ntom lossis granules.
keeb kwm ntawm ribosomal RNA yog dab tsi?
Molecules ntawm rRNA yog synthesized nyob rau hauv ib cheeb tsam tshwj xeeb ntawm lub cell nucleus hu ua lub nucleolus, uas tshwm sim raws li ib tug ntom cheeb tsam nyob rau hauv lub nucleus thiab muaj cov noob uas encode rRNA.
