A. How long will the coding region of the processed mRNA transcript be? (Remember that stop codons are indeed transcribed into mRNA.) B. How many amino acids will be included in the translated protein? (Careful!) I
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
A. In an mRNA exons refer to the coding region while introns refer to the non-coding regions. During the process of mRNA splicing the non-coding introns are spliced off the mRNA joining the coding exons with each other.
So, the processed mRNA will have a translation start site, exons joined to each other, and the poly-A tail while introns will be eliminated.
Hence the length of the coding region will be the length of Exon1 +Exon2 +Exon 3 =90+110+70 =270 bases.
