Absolutely, let's break down the practical steps involved in studying ancient DNA:

1. **Sample Collection**: The first step is to find a suitable sample. This could be a bone, tooth, or even preserved hair from an extinct species. The sample needs to be well-preserved and not contaminated with modern DNA. In some cases, scientists may use ancient seeds or plant material.

2. **DNA Extraction**: Once a suitable sample is found, the next step is to extract the DNA. This is often done in a specialized clean room to prevent contamination from modern DNA. The sample is usually ground into a powder and then treated with chemicals that break open the cells and release the DNA.

3. **DNA Sequencing**: The extracted DNA is then sequenced. This involves determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The challenge with ancient DNA is that it is often fragmented and damaged, so scientists may need to use specialized techniques to sequence it.

4. **Data Analysis**: Once the DNA has been sequenced, the data is analyzed using bioinformatics software. This can involve comparing the ancient DNA sequence with the sequences of modern species to identify similarities and differences. This helps scientists understand the evolution and extinction of species.

5. **Genome Assembly**: The final step is to assemble the sequenced DNA into a complete genome. This is like putting together a jigsaw puzzle where the pieces are the sequenced DNA fragments. This process is guided by comparison with the genomes of related, modern species.

6. **Interpretation and Publication**: Once the genome is assembled, scientists can study it to learn about the extinct species' traits, behavior, and evolution. The findings are typically published in scientific journals.

It's important to note that this is a simplified explanation and each step involves a lot of technical detail and expertise. Also, the success of the process greatly depends on the quality of the ancient DNA and the available resources.
