Protein synthesis is made up of two steps which are transcription and translation. The transcription part is when the information that is encoded in the DNA is taken away and it is the encoded in the mRNA and this information can then go to the cells that are within the nucleus and then onto in the cytoplasm. Then there is translation which is when the mRNA works with a ribosome and tRNA to be able to synthesize the proteins.
Transcription
The sequence of transcription starts with the Enzyme Helicase being able to attach to the DNA double helix. By attaching to the double helix, it means that the enzyme helicase is able to unwind the DNAs double helix which enables part of the DNA code that is needed for the protein is then exposed which enables it to be transcribed. The DNA is now unwound in the area that is needed so the RNA polymerase is able to help line up the nucleotides to create a complementary strand of the mRNA. Between the strands there are hydrogen bonds which are then separated apart. One of the strands is then able to be used as a template strand. Onto this template strand these is base pairing which is the DNA cytosine joining to the RNA guanine, DNA guanine joining to the RNA cytosine, DNA thymine joining to RNA adenine and DNA …show more content…
Within this there is a triplet code and this is a sequence of three nucleotides bases which can then code for a certain amino acid. These are coded for by there being four bases which are arranged in groups of three and there can be a total of 64 different combinations of the codes. For each of the amino acids there can be multiple codes for them as the genetic code can be a degenerate code so an amino acid can have a number of codes for it and for a chromosome there can be many genes for
