Excitability WebIt involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.

WebEach hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule. Each iron atom can form six coordination bonds. Two of these bonds are formed between iron and oxygen. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.
Myoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. Myoglobin is distantly related to hemoglobin. Compared to hemoglobin, myoglobin has a higher affinity for oxygen and does not have cooperative binding with oxygen like hemoglobin does.
