Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. <span>5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. </span>
Explanation:
Translation is catalyzed by a large enzyme called a ribosome, which contains proteins and ribosomal RNA (rRNA). Translation also involves specific RNA molecules called transfer RNA (t-RNA) which can bind to three basepair codons on a messenger RNA (mRNA) and also carry the appropriate amino acid encoded by the codon.
The correct answer is C. Translation.
The given figure is the scheme of the gene expression. It provides the flow of genetic information from a DNA sequence to a protein synthesis inside cells. This process of flow of genetic information from DNA to RNA is called transcription and the process of flow of genetic information from RNA to protein is called translation.
Thus in given figure label A is to be replaced by transcription and label B is to replace by translation.
Answer:
The catalytic efficiency of the enzyme depends on several factors that can affect the activity of the enzymes. This factors include Temperature, pH, concentration of the substrate, concentration of enzyme and the presence of activators and inhibitors.
Explanation:
The catalytic efficiency of the enzyme depends on several factors that can affect the activity of the enzymes. This factors include Temperature, pH, concentration of the substrate, concentration of enzyme and the presence of activators and inhibitors.
For instance, the pH is an essential factor that has to be maintained properly for the appropriate catalysis by an enzyme. The most favorable pH of most of enzymes present from 6 to 8.
