Transcription is the biological process where the DNA sequence of a gene is copied into RNA, which serves as a template for protein synthesis. This crucial step in gene expression is regulated by various factors ensuring that the right genes are expressed at the right time and in the right amount.

Transcription

A biological process is a series of events or molecular functions that occur in living organisms to sustain life, such as metabolism, cell division, or photosynthesis. These processes are essential for growth, development, reproduction, and maintaining homeostasis in an organism.

biological process

A DNA sequence is a specific linear arrangement of nucleotides (adenine, thymine, cytosine, and guanine) that encodes the genetic information of an organism. This sequence determines the synthesis of proteins and regulates various biological processes, impacting traits and functions at the cellular and organismal levels.

DNA sequence

A gene is a fundamental unit of heredity in living organisms, consisting of a sequence of DNA that encodes instructions for the synthesis of proteins or functional RNA molecules. Genes determine the inherited traits of organisms and play a crucial role in biological processes and evolution.

Ribonucleic acid (RNA) is a crucial molecule in cellular biology that plays a central role in coding, decoding, regulation, and expression of genes. It serves as the intermediary between DNA and protein synthesis, and is involved in various biological processes including gene regulation and catalysis.

template for protein synthesis

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically proteins, which ultimately determine cellular function and phenotype. This process is tightly regulated at multiple levels, including transcription, RNA processing, translation, and post-translational modifications, to ensure proper cellular function and response to environmental cues.
