1, gene sequence analysis
Sequence comparison, bioinformatics reveals the similarities and differences between sequences by comparing the gene sequences of different species or individuals, and provides a basis for species classification and evolution research. Structural prediction is based on known gene sequences. Bioinformatics can predict the structure of genes, such as the double helix structure of DNA and the three-dimensional structure of protein, which is helpful to understand the functional mechanism of genes.
2. Gene expression analysis
Transcriptomics studies the expression of genes in different tissues, different developmental stages or different environmental conditions by analyzing the quantity and types of transcripts. Protein omics studies reveal the relationship between genes and diseases, development and other processes by studying the expression, modification and interaction of protein.
3. protein's omics research.
Protein structure prediction is based on the known amino acid sequence. By predicting the three-dimensional structure of protein, it is helpful to understand the function and mechanism of protein. Interaction analysis reveals the complex network relationship in the life process by studying the interaction between protein, and provides a target for drug research and development.
4. Genome evolution research.
Molecular evolution analysis reveals the traces and laws of evolution by comparing the gene sequences of different species or individuals, and provides clues for studying the origin of species and biodiversity. The study of paleogenomics reveals the history and process of life evolution by analyzing the genome data of paleontology, and provides important information for understanding the origin and evolution of life.
