Report Abuse. mRNA id made from DNA by a process which is called Transcription. The master blueprint is DNA, which contains all of the information to build the new protein (house). The working copy of the master blueprint is called messenger RNA (mRNA), whicÂ­h is copied from DNA.RNA, or messenger RNA, is generated by reading a strand of DNA. RNA polymerase (an enzyme that specifically makes mRNA) moves along the strand of DNA and joins complementary strands (in RNA, the complement to adenine is uracil instead of thymine). mRNA is produced only for the gene that is being read at that time.
Cellular Respiration: as organisms use food to make energy in the process of cellular respiration, carbon dioxide is produced. All types of biological molecules can be processed in cellular respiration to generate energy and, therefore, carbon dioxide.
Blood arriving in the alveoli has a higher carbon dioxide concentration which is produced during respiration [respiration: Chemical change that takes place inside living cells, which uses glucose and oxygen to produce the energy organisms need to live. Carbon dioxide is a by-product of respiration.] by the bodyâs cells.
