The ribosome is the cellular machinery responsible for protein synthesis.
核糖体是负责蛋白质合成的细胞机器。
In bacteria, ribosomes are much smaller than those in eukaryotic cells.
在细菌中，核糖体比真核细胞中的要小得多。
Translation begins when the messenger RNA (mRNA) binds to a ribosome.
当信使RNA（mRNA）与核糖体结合时，翻译过程开始。
Ribosomes can be found in both the cytoplasm and the endoplasmic reticulum of a cell.
核糖体可以在细胞的胞质和内质网中找到。
Each ribosome consists of two subunits, a large one and a small one.
每个核糖体由一个大亚基和一个小亚基组成。
The ribosome reads the genetic code on the mRNA three nucleotides at a time.
核糖体每次读取mRNA上的三个核苷酸组成的遗传密码。
During translation, amino acids are added to the growing polypeptide chain by the ribosome.
在翻译过程中，核糖体会向正在增长的多肽链上添加氨基酸。
Antibiotics that target bacterial ribosomes can inhibit protein synthesis and kill the bacteria.
目标定位在细菌核糖体的抗生素可以抑制蛋白质合成并杀死细菌。
Ribosomes are essential components of all living organisms, from prokaryotes to eukaryotes.
核糖体是从原核生物到真核生物的所有生命体的基本组成部分。
Researchers have been able to visualize the structure of ribosomes using techniques like cryo-electron microscopy.
