Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick. Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation. Transcription is the synthesis of RNA molecules by RNA...

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

What is Gene Expression?

Overview Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors. Genetic Information Flows from DNA to RNA to Protein A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
FAQs
Regulatory elements and RNA processing help control more than whether a protein-coding gene is present. They influence when and where messenger RNA is produced and processed, which affects the protein available to a cell. This layer of control helps explain how the same genetic information can contribute to different cellular activities during development or in distinct tissues.
At translation, ribosomes read messenger RNA in the sequence specified by the genetic code and assemble amino acids into a protein. A variant within the coding information can therefore alter the resulting amino acid sequence, while other changes may affect protein abundance. Distinguishing these outcomes helps connect genetic differences with altered molecular function and inherited disease.
Protein-coding genes can affect phenotype through both protein sequence and production level. A sequence change may modify the amino acid instructions, whereas altered regulation or RNA processing may change how much protein is made or where it is produced. Considering both routes prevents analysis from focusing only on the protein’s structure when interpreting genetic variation.
A useful analysis framework follows the information flow from DNA to messenger RNA to protein: researchers examine the gene, consider its RNA processing and regulation, and then evaluate possible effects on protein sequence or abundance. This approach organizes genetic testing and functional studies, allowing investigators to move from a detected variant toward a hypothesis about molecular consequences.
Genetic testing can use protein-coding genes to investigate variants associated with inherited disease. Interpretation requires asking whether a finding could change the encoded amino acid sequence or the amount of protein produced, rather than treating every variant as equivalent. The result can connect a genetic observation with a possible biological effect, while functional studies provide a way to investigate that connection.
In functional studies, researchers can examine how a protein-coding gene’s information relates to protein production and cellular roles such as structural, enzymatic, regulatory, or transport activity. These studies help investigate disease, development, and adaptation by linking gene changes to protein-related outcomes. The same knowledge also supports research aimed at designing targeted therapies.
