Question

Imagine you are producing a short film depicting the molecules and biological processes involved in gene expression. For this, you need to first create a storyboard for your film. A storyboard is a sequence of drawings, along with some description or dialogue, that illustrates and represents the scenes of a story or movie. Create a storyboard for the process of gene expression/central dogma depicting the story of how the cell uses the information in DNA to synthesize a protein.

Answer 1

A storyboard of gene expression would illustrate the central dogma of molecular biology, showcasing the processes of transcription within the nucleus and translation at the ribosome to synthesize a protein from the genetic information encoded in DNA.

Step-by-step explanation:

The process of gene expression, described by the central dogma of molecular biology, involves the flow of genetic information from DNA to mRNA to protein. It begins with transcription, where a particular gene on the DNA is activated, unwinds, and serves as a template to synthesize a complementary strand of mRNA. This occurs in the nucleus and includes three stages: initiation, where RNA polymerase binds to the promoter sequence; elongation, where RNA nucleotides are added to form the mRNA strand; and termination, once a stop signal is reached. The next step is translation, which occurs in the cytoplasm at the ribosome, where the mRNA is used to determine the sequence of amino acids in a protein. Three nucleotides on the mRNA, known as a codon, correspond to one amino acid. Through initiation, elongation, and termination, the amino acid chain forms and eventually folds into a functional protein.

Answer 2

By decoding information with the help of transfer RNA (tRNA).

Step-by-step explanation:

The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.
