Question

Which mode of information transfer usually does not occur?

Answer 1

Hint: Translation is the method that converts the information released from the DNA, which is carried by messenger RNA, into a string of amino acids which is combined with the help of peptide bonds. Essentially, it involves translating a code (such as a nucleotide sequence) into another code (amino acid sequence).
Complete step-by-step solution:
A cell must first translocate information from DNA to mRNA through transcription in order to produce protein molecules. This mRNA is then used as a template for protein construction during a process known as translation. In order to create the proteins that do the cell's task, the cell employs the genetic information included in the mRNA during translation. The mRNA code is converted by the cell into a new language called the language of proteins, which is based on amino acids.
One of the core concepts in molecular biology is the information transfer from DNA to RNA to proteins. Because of its significance, it is also referred to as the "core concept." Information from genes is utilised to generate proteins through transcription and translation processes. However, there isn't a direct transfer of information from DNA to protein.
Hence, option C is the correct answer.
Note:
The procedure of introducing genetic material (DNA or RNA) into a person is known as human gene transfer or gene therapy. Signals indicating the proper home of each protein molecule are encoded within the DNA structure of genes. Thus, the stability and uniformity of living cells are maintained via the communication of information from one macromolecule to another. Gene therapy is a type of medical treatment that alters the genetic makeup of live cells before being administered to people.
