Translation is a complex process that translated the genetic information from the language of DNA in the language of RNA. The first step in this process is the binding of the initiator tRNA (that is bound to the aminoacid methionine) to the small ribosomal unit. Then, the small ribosomal unit joins the mRNA; it is the part of the ribosome mainly responsible for translating. After that, the initiator tRNA binds to the start codon. This reaction frees some initiation factors that make large ribosomal units bind to the small one. Hence, <span>the large ribosomal subunit completes the initiation complex afterwards. The role of the large ribosomal unit is mainly to make the peptidic bonds between the aminoacids in the new protein. After that, </span><span>amino acids are paired with anticodons, gradually forming a long chain</span>; this chain is called a polypeptide and is the skeleton of the protein that is created. Finally, this process stops when one of the three possible stop codons are reached.
Binary fission and mitosis are both asexual forms of cellular reproduction that duplicate the existing DNA in a mother cell and split the cell into two exact copies called daughter cells.
Answer:
C. Utilization of fossil fuels by humans for industrialization.
Explanation:
Frequent eruptions of large volcanoes were happening long before humans and will happen after humans too. They are not the reason why we are seeing so much CO2 in the last 200 years.
There are some naturally occurring fluctuations of carbon but not to the degree that we are seeing.
Melting of ice and sea levels rising is due to the global warming problem caused by our dependency on fossil fuels.
