What is the cellular process shown below for x, y, and z?

The cellular process shown in the image as x, y and z are mentioned below:

X is Replication. It is the process by which double- DNA Replication is the process by which double stranded DNA makes its own copies. Each strand on its separation, synthesizes a complementary stand.  

Y is Transcription. It is the process by which copying of the information from a strand of DNA into a new molecule of mRNA, with the help of an enzyme RNA polymerase.

Z is Translation. It is the process in which genetic code on mRNA is decoded to produce the specific sequence of amino acids to form a polypeptide chain.  

i'd say that the moon rock is about 2.2 billion years old.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
