Sequence analysis is a method used to study the order of nucleotides in DNA or RNA, or the sequence of amino acids in proteins. This technique helps scientists understand genetic information, identify mutations, and explore evolutionary relationships among organisms. By comparing sequences, researchers can determine similarities and differences that provide insights into biological functions and processes. In bioinformatics, sequence analysis often involves using algorithms and software tools to align sequences and predict their structure and function. This approach is essential for fields like genomics, proteomics, and molecular biology, enabling advancements in medicine, agriculture, and environmental science.
