In bacteria, there are three major types of RNA; mRNA, tRNA and rRNA. All three RNAs are needed to synthesize proteins in a cell. The mRNA provides the template, tRNA brings amino acids and reads the genetic code, and rRNAs play structural and catalytic role during translation. Many times translation begins much before the mRNA is fully transcribed.

जीवाणु में आरएनए (RNA) के तीन मुख्य प्रकार - दूत आरएनए (mRNA), अंतरण आरएनए (tRNA) तथा आर आरएनए (rRNA) होते हैं। सभी तीनों आरएनए (RNAs) एक कोशिका में प्रोटीन के संश्लेषण के लिए आवश्यक होते हैं। दूत आरएनए (mRNA) टेम्पलेट प्रदान करता है, अंतरण आरएनए (tRNA) अमीनों अम्ल लाता है एवं आनुवंशिक कोड को पढ़ता है तथा आर आरएनए (rRNAs) अनुवादन के दौरान संरचनात्मक तथा उत्प्रेरकी भूमिका निभाता है। कई बार दूत आरएनए (mRNA) के पूर्ण रूप से अनुलेखित होने से बहुत पहले ही अनुवादन शुरू हो जाता है।
