What kind of mutation isProcess of translation *( Choose True if the statement is correct about Process of translation and False if otherwise ) includes covalent modification of some proteins participation of rRNA transfer RNA is made from messenger RNA tRNA uses information from mRNA to produce amino acid chainsIove aIung the HRNA from codon to codon, the appropriate amino acids are brought into place and linked together according to the sequence of codons. Thus, the code in the mRNA is translated into a special sequence of amino acids. The order of the amino acids in the protein, therefore, is specified by the MRNA, which in turn is transcribed from the DNA. Procedures and Observations: During transcription, the DNA double helix unwinds and "unzips. The two strands separate as the hydrogen bonds binding the nitrogen bases break. Then, nucleotides present in the cell line up along one strand of the DNA, the order of the nucleotides determined by the order of the nucleotides in the DNA. As the mRNA forms, uracil (U) nucleotides match with adenine (A) nucleotides; cytosine (C) nucleotides match with guanine (G) nucleotides. Note: RNA contains uracil (U) nucleotides where thymine (T) nucleotides would occur in DNA. The nucleotides in the newly formed mRNA are complementary to the nucleotides of…

The most effective antibiotics work by interfering with essential biochemical or reproductive processes. Many antibiotics block or disrupt one or more stages in protein synthesis. Some of these are mentioned here. Tetracyclines are a family of chemically related compounds used to treat several types of bacterial infections. Tetracyclines interfere with the initiation of translation. The tetracycline molecule attaches to the small ribosomal subunit and prevents binding of the tRNA anticodon during initiation. Both eukaryotic and prokaryotic ribosomes are sensitive to the action of tetracycline, but this antibiotic cannot pass through the plasma membrane of eukaryotic cells. Because tetracycline can enter bacterial cells to inhibit protein synthesis, it will stop bacterial growth, helping the immune system fight the infection. Streptomycin is used in hospitals to treat serious bacterial infections. It binds to the small ribosomal subunit but does not prevent initiation or elongation; however, it does affect the efficiency of protein synthesis. Binding of streptomycin changes the way mRNA codons interact with the tRNA. As a result, incorrect amino acids are incorporated into the growing polypeptide chain, producing nonfunctional proteins. In addition, streptomycin causes the ribosome to randomly fall off the mRNA, preventing the synthesis of complete proteins. Puromycin is not used clinically but has played an important role in studying the mechanism of protein synthesis in the research laboratory. The puromycin molecule is the same size and shape as a tRNA/amino acid complex. When puromycin enters the ribosome, it can be incorporated into a growing polypeptide chain, stopping further synthesis because no peptide bond can be formed between puromycin and an amino acid, causing the shortened polypeptide to fall off the ribosome. Chloramphenicol was one of the first broadspectrum antibiotics introduced. Eukaryotic cells are resistant to its actions, and it was widely used to treat bacterial infections. However, its use is limited to external applications and serious infections. Chloramphenicol destroys cells in the bone marrow, the source of all blood cells. In bacteria, this antibiotic binds to the large ribosomal subunit and inhibits the formation of peptide bonds. Another antibiotic, erythromycin, also binds to the large ribosomal subunit and inhibits the movement of ribosomes along the mRNA. Almost every step of protein synthesis can be inhibited by one antibiotic or another. Work on designing new synthetic antibiotics to fight infections is based on our knowledge of how the nucleotide sequence of mRNA is converted into the amino acid sequence of a protein. Questions Why are antibiotics ineffective in treating the common cold and other virus infections?
