From RNA to Protein Synthesis - YouTube

The order of the nitrogenous bases on a strand of DNA (or in a section of the DNA that comprises a gene) determines which amino acid is produced. And the order that amino acids are strung together determines which protein is produced. Which protein is produced determines what structural element is produced within your body (such as, muscle tissue, skin, or hair) or what function can be performed (such as if hemoglobin is being produced to transport oxygen to all the cells).

what is the role of DNA in protein synthesis

DNA-driven nanoparticle assembly provides a powerful tool for the fabrication of superlattices with tunable composition, structure, and inter-particle distance. DNA is chemically stable and can be conveniently applied to functionalize nano-objects and provide a high degree of encoding in the assembly process. The high specificity of DNA—its unique ability to recognize and bond with complementary sequences—permits the programming of nanoparticle interconnections and allows us to create multi-functional materials. We can then leverage that synthesis knowledge to investigate any emergent and collective phenomena.

what role does mRNA play in protein synthesis

For example, RNA has three major subtypes: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three of those subtypes are involved in protein synthesis.

Ribosomes and Protein Synthesis

The mutant drpA1 defines a new gene in Escherichia coli K-12 that maps at about 5.2 min. This mutation was obtained after enriching a population of cells for temperature sensitive dna mutations with the [3H]thymidine 'suicide' technique followed by screening for mutants defective in transposon Tn5 precise excision. When growing cells carrying the drpA1 allele were shifted to the nonpermissive temperature, we showed that DNA, RNA, and protein synthesis shut off quickly, with the cessation of RNA synthesis occurring first. A recombinant plasmid between pBR322 and an HindIII fragment from wild-type E. coli restores the growth defect in drpA1 mutants. Using transposon Tn5 mutagenesis of this plasmid, we have been able to correlate the presence of a 68-kilodalton protein, as observed with the maxicell technique, with the ability of this plasmid to restore growth to drpA1 mutants.

What Is The Role Of Transcription In Protein Synthesis

Sixty three nucleotides are required for synthesising the A chain and ninety for the B chain, plus a codon at the end of each chain,signalling the termination of protein synthesis.

Scientists Probe Role of Nucleus in Protein Synthesis

There are four different nitrogen bases, adenine, thymine, cytosine and guanine. The synthesis of a particular protein such as insulin is determined by the sequence in which these bases are repeated (see fig.
