The process and outcome of genetic transcription; enzyme involved in transcription; the difference between pre-mRNA and mRNA; and the significance of introns and exons. Introduction: DNA is a genetic material consisting of a long stretch of nucleotide sequences with 2 m length. It carries genetic information from one generation to the next. A complete set of genetic materials (both coding and non-coding regions of DNA) of an organism is called as genome. The total human genome consists of about 3.1 billion base pairs and nearly 20,000 protein coding genes. DNA replication is the first step in the central dogma of biology followed by transcription and translation. In replication, two identical copies of DNA sequences are produced from the single DNA sequence. Synthesis of mRNA from DNA is known as transcription, followed by translation, in which protein is synthesized from the mRNA sequence.

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
