This document illustrates the fundamental biological processes of transcription and translation. Transcription is depicted as the process where a DNA template strand is used to create a messenger RNA (mRNA) transcript. Following this, translation is shown as the process where the mRNA sequence is decoded to produce a polypeptide chain, specifically illustrating the sequence of amino acids Methionine (Met), Isoleucine (Ile), and Serine (Ser). The diagram clearly labels the coding strand, template strand of DNA, the resulting RNA transcript, and the final polypeptide product, providing a visual explanation of gene expression from DNA to protein synthesis. The sequence of nucleotides AT GATCTCGTAA on the coding strand is shown to correspond to the template strand TACTAGAGCATT. During transcription, the template strand TACTAGAGCATT directs the synthesis of mRNA with the sequence AUGAUCUCGUAA, where Uracil (U) replaces Thymine (T). The subsequent translation process utilizes codons from this mRNA to assemble amino acids into a polypeptide.

FAQs

What are the two main processes depicted in the diagram?

The diagram illustrates two main biological processes: transcription and translation.

What is the role of the template strand in transcription?

The template strand of DNA serves as a guide for synthesizing a complementary RNA transcript during transcription.

What is the final product of translation?

The final product of translation is a polypeptide chain, which is a sequence of amino acids.
