What is forensics ?
Scientific analysis of evidence for crime scene investigations and other legal proceedings. Forensics involves DNA identification, finger prints etc...
Why do we need forensics ?
Forensics helps us to validate people that were at the crime scene. Due to forensics we can identify people's DNA and thus have a better evidence in solving the crimes. The first time DNA technology was used to solve a crime was in 1986 by Alec Jeffreys.
Diagram :
This diagram shows how gene therapy can help treat certain diseases by altering viruses DNA so it helps the body to heal.
5facts:
Vaccine is harmless variant of a pathogen, used to mount system against that pathogen
Genetically modified organisms are ones that required one or more genes by artificial means
STR analysis is a method of DNA profiling that compares the lengths of STR sequences at specific sites
PCr method is use to amplify DNA sequences.
Recombinant cells and organisms can mass-produce gene products that later on are used to treat certain diseases
Key terms :
plasmids - small circular DNA molecules that replicate separately from the much larger bacterial chromosome
genomic library - DNA fragments from a genome
vector - gene carrier
transgenic organism - recombinant organism
DNA profiling - analysis of DNA fragments
primers - short chemically synthesized single-stranded DNA molecules with sequences that are complementary to sequences at each end of the target sequence
genomics - science of studying a complete set of genes
transposable genes - genes that can move or be copied from one location to another
repetitive DNA - DNA that consists of nucleotide sequences that are present in multiple copies

Summarize :
This chapter gave us an overview of different uses of genes. We can either solve crimes, modify plants and animals, categorize genes etc.
