Answer:
The visible DNA fingerprint can help extract DNA which, after analysis, can accurately identify the suspect or perpetrator of the crime.
Explanation:
DNA Fingerprinting:
- DNA fingerprinting is a molecular analysis tool that can help identify a suspect in a crime through DNA extracted from fingerprints.
- Specific patterns in the DNA, known as polymorphisms, can be identified through DNA fingerprinting.
- The DNA fingerprinting process involves:
- Extraction and purification of the DNA from the fingerprint.
- PCR amplification to obtain high yield.
- Fragmentation of the DNA by use of restriction enzymes.
- Gel electrophoresis analysis of the fragmented DNA.
- Analysis of gel to compare the size of the bands.
Answer:
Organs are made of different kinds of tissues that work together.
Explanation:
All the organs are made of tissues, the organ level is the next level up from tissues. The groups of tissues work together. The tissues are specialized cell group, the animal body is made of 4 types of tissues: epithelial, connective, muscle, nervous.
Organs and tissues are levels of organization. Organs are structures made up of two or more tissues, together they carry out a particular function.
Nutrition, respiration ,growth excretion, homestais, reproduction, movement, and sensitivity
