👉 Sequencing is a process used to sequence DNA or RNA sequences. This means that it involves taking a sample of DNA (the genetic material) from an organism and measuring the amount of information encoded in the DNA sequence. The goal of sequencing is to identify which genes are expressed at different stages of development, such as embryonic stem cells, embryos, or adult organisms. Sequencing can be done using various techniques, including PCR (Polymerase Chain Reaction), RT-PCR (Reverse Transcript
