Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Thanatotranscriptome?Forensic science, specifically for post-mortem interval estimation
2. What is the scientific name?Thanatotranscriptome
3. What is the temporal window?RNA production can persist for up to 48 hours post-mortem
4. Why does the body keep making RNA after it dies?After death, the parts of cells that make RNA, like ribosomes and transcription factors, can still work for a short time. Because RNA is stable, the cells can keep making new RNA even though the body is no longer alive.
5. How can scientists use the thanatotranscriptome to learn when someone died?By looking at which RNA molecules are present and how many of them there are, scientists can estimate how long it has been since the body died. This helps them figure out the time of death in investigations.

RNA Transcripts: Single-stranded nucleic acid molecules that are copies of DNA segments, serving various roles including carrying genetic information.
Genome: The complete set of genetic material present in a cell or organism, encompassing all DNA and genes.
Gene Expression: The regulated process by which information encoded in a gene is used to synthesize a functional gene product, typically a protein.
Thanatology: The scientific study of death, dying, and the processes that occur in the body after death.
