The first step in the development of a complex organism is the establishment of a pattern of cells with different states that can differentiate along different pathways. … [P]atterning processes require signalling between and within cells, leading ultimately to gene activation or inactivation. Such a process can lead to reliable patterns of cell activities only if all the cells have the same set of genes and obey the same rules<span> [</span>
The sequence of amino acid in polypeptide is dictated by the codons in the messenger RNA molecules from which polypeptide was translated. The sequence of codons in the mRNA was in turn dictated by the sequence of codons in the DNA from which the mRNA was transcribed. The amino acids are linked covalently by peptide bonds.
These types of nerves are called "Sensory Neurons" :)
The DNA is zipped open by the enzyme DNA helicase, to form two singles strands of DNA for that specific area of the DNA.
Then RNA nucleotides are joined to the sense strand to form a complementary strand of RNA, the RNA is small enough to leave the nucleus by the nuclear pores and go to the ribosomes. This process is called transcription
Metabolism can be described as the
chemical process that involves the breakdown of food consumed to give energy
which can be used to carry out activities by living organism. The consumption
of oxygen can be adopted as a means to estimate the metabolic rate because oxygen
is required for synthesis of ATP ( Adenosine Tri-Phosphate) through oxidative phosphorylation. Also, it is
important for fermentation to occur as well as helps in replenishing low level
of glycogen
