Answer:
The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.
Explanation:
In protein synthesis, the first step is to <em>synthesize messenger RNA</em>, mRNA. The coping process of the DNA section for the desired protein is called <u><em>transcription</em></u>, and it happens in the <em>nucleus</em>. After that, it occurs <em><u>translation</u></em>, when the formed <em>mRNA moves to the </em><em>cytoplasm</em> through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of <em>protein and ribosomal RNA</em> and can be found in the r<em>ough endoplasmic reticulum</em> or floating in the <em>cytosol</em>. They read the mRNA code and add the correct amino acid using <em>transference RNA</em> to build the protein. mARN has a <em>start and end codon</em> that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is <em>folding</em> to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.
Answer:
Catalase behaves as a catalyst for the conversion of hydrogen peroxide into water and oxygen.
Explanation:
Catalase is an antioxidant enzyme that plays a very important role in the protection against oxidative damage by breaking down hydrogen peroxide. It is a very highly conserved enzyme that has been identified from numerous species including bacteria, fungi, plants and animals.
Catalase has one of the highest turnover numbers for all known enzymes (40,000,000 molecules/second). This high rate shows an importance for the enzymes capability for detoxifying hydrogen peroxide and preventing the formation of carbon dioxide bubbles in the blood.
It is based on shared characteristics
