Génszekvenciák

Génszekvenciák, often translated as gene sequences or genetic sequences, refer to the specific order of nucleotide bases (adenine, guanine, cytosine, and thymine – A, G, C, T) within a DNA or RNA molecule. These sequences contain the genetic instructions for the development and functioning of all known living organisms and many viruses. The arrangement of these bases is not random; it forms codons, which are three-base units that specify amino acids, the building blocks of proteins. The complete set of genetic information in an organism is called its genome, and within the genome, specific regions that code for functional products are known as genes.

Understanding gene sequences is fundamental to modern biology and medicine. Techniques like DNA sequencing allow scientists to determine the precise order of nucleotides in a gene or an entire genome. This information is crucial for identifying genes, understanding their functions, and studying genetic variations that can lead to diseases. The study of gene sequences has opened doors to personalized medicine, gene therapy, and advancements in evolutionary biology, allowing us to trace the relationships between different species and understand the history of life on Earth. Variations in gene sequences are responsible for the diversity observed in all living things.
