write the formula which shows the sequence of events that results in the production of a new protein molecule.

Question

then explain what is happening in each step of the sequence

Answer 1

Central Dogma of Molecular Biology

DNA -----> RNA --------> Protein
Transcription Translation

During Transcription, there are many required substances for transcription to be carried out. There must be a promoter and various transcription factors bound on the gene of interest. The RNA polymerase must also be attached to the promoter.

Genes are then transcribed from the DNA and the transcribed is known as the pri-mRNA. The pri-mRNA then goes through splicing to form the mRNA.

During Translation, the mRNA would move to the ribosome and the tRNA bringing the amino acid would match with the mRNA sequence. If the sequence fails to match, the tRNA would leave the ribosome with the amino acid. If it matches, the amino acid stays and the tRNA leaves alone.

After the chain of polypeptide is form, it then undergoes post-translational modification. Folding, intein splicing, phosphorylation and other modification would take place to assure that the protein is functional.

Answer 2

DNA --> RNA --> protein the central dogma of molecular biology, there are lots of information you can fill in the blanks represented by the arrows above (genes, introns, extrons, miRNA, mRNA, ribosomes, codons etc...)
