In prokaryotes, the ribosomes binding site (RBS) on the mRNA is called the Shine-Dalgarno sequence. It is present in the 5' UTR region. It is made up of purine bases. A. Hogness sequence is also called the TATA box and these are present in the promoter region of a gene on the DNA...
Answer to: Ribosomes - are not found in prokaryotes. - carry genetic information. - carry out translation. - contain RNA only. - None of the above...
What are the main cell structures and functions in both eukaryotes and prokaryotes? What are three cellular components that are present in both prokaryotes and eukaryotes? Explain the function of mitochondria, ribosomes, and lysosomes. One difference between eukaryotes and prokaryotes is that: A. pro...
The intact ribosome is of the 80S type. Mitochondrial ribosomes are of the 70S type or, in ciliates, 80S. The mitochondrial ribosomes are similar to those of prokaryotes ( Eukaryota /Table 1 ). 展开 关键词: ribosomes DOI: 10.1002/047120918X.emb1337 被引量: 7 ...
In prokaryotes, as well as chloroplasts and mitochondria, the monomeric particle sediments in the 70 S range, though can be dissociated into a larger 50 S and a smaller 30 S particle. It contains 23 S, 16 S, and 5 S RNA and at least 50 proteins. Eukaryotes, in contrast, have ...
The process of translation in prokaryotes begins with the initiation factor IF3 that stimulates the mRNA to bind with the smaller subunit of the ribosome. Then the initiation factor IF2 binds with the GTP molecule and a tRNA that carries N-formylmethionine amino acid. This allows the tRNA to...
In contrast, prokaryotes lack a well-defined nucleus so that the genetic material in the form of double stranded DNA is not separated from other cell constituents by its own membrane. These cells also lack other specialized organelles present in eukaryotes. Bacteria may contain small DNA fragments...
iv. The cell membrane of prokaryotes is structurally similar to the eukaryotes. Choose the option with the correct statements. View Solution Ribosomes are associated with View Solution Ribosomes are essential for protein synthesis but they are present in mitochondria and plastids , the sites of ...
The dissociation of ribosomes into subunits is reversible. The gross structure of a prokaryotic (bacterial) ribosome is shown in Figure 1. The structure of a typical eukaryote ribosome is very similar; however, ribosomes from prokaryotes and eukaryotes differ in size....
Does elongation in ribosomes use energy? What organelles are found in prokaryotes? What organelle contains DNA in eukaryotic cells? What are the similarities between prokaryotes and eukaryotes? Which of the following carries amino acids to the ribosomes where they are linked together to form a poly...
