WebMar 4, 2024 · Transcription in prokaryotic cells:_____. a. is initiated at a promoter and uses only one strand of DNA (the template strand) to synthesize a complementary RNA strand. b. is terminated at a stop codon. c. is initiated at a start codon with the help of initiation factors and the small subunit of the ribosome. d. does not need a promoter. WebSubunit joining also requires eIF5B, which is a homolog of the prokaryotic initiation factor 2 and, like it, has a GTPase activity that is maximally stimulated by large and small ribosomal subunits. Subunit joining leads to the release of all initiation factors from the 40S subunit and leaves Met-tRNA i Met in the ribosomal P site.

WebIn prokaryotes, how is mRNA recruited to the small ribosomal subunit for translation initation? The RBS site located on the 5' end of a prokaryotic mRNA sequence is complimentary to the 16 rRNA sequence found in the small subunit. This positions the ribosome near the start codon.

WebA ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).
