Describe the process of gene regulation in eukaryotes.
Genes are specific sets of nucleotides that are located on the chromosomes, and these genes consist of introns and exons. The genes serve as independent hereditary units that are transmitted from one generation to another. Genes are translated to form proteins in the cell.
Answer and Explanation: 1
The gene expression regulation in eukaryotes takes place with the help of various factors like transcription activators and repressors. These proteins bind to specific sequences and promoters to activate or inhibit the transcription of genes that initiate or repress different biochemical pathways. The gene regulation occurs at specific events through epigenetic changes, post-transcriptional modifications, post-translational modifications, and transcriptional changes. The gens that are required are activated by modifications through methylation, acetylation, and so on. The genes products that are not needed for the cell, the corresponding genes are inactivated by preventing their modification after transcription, thereby regulating the concentration and presence of gene products (proteins) in the cell.
