Question

Biomolecules:(cite appropriately- we use Concepts of Biology 978-1-938168-11-6) • specific properties of biomolecules and what that means for how the molecule works, • bonding of biomolecules and why that's important, • specific features of a certain type of biomolecules, • how they can be identified and quantified, or • how they can be used in forensic analysis. You should try to incorporate some information from the chapter and follow that up by looking things up for yourself in order to elaborate on what you are presenting to the class in your posting.

Explanation / Answer

Answer : Biomolecules are thoses structural and finctional molecules which is involved in maintenance and metabolic processes of living organisms.

Types:

Protein-made up of amino acid. Mostly present in the cell membrane . So helps in getting the structure of the cell

Lipids: made up of fatty acid and glycerol. It is also present in cell membrane. Lipid layers has polar head and non polar tail. Helps in the flexibility of the membrane and ion entries of the cell.

Nucleotide : made up of DNA and RNA. They have nitrogenous bases. Contains gene. Nucleotide are bonded with each other by phophodiester bond. Adenine guanine thymine and cytosine are present in DNA molecule and uracil is present in RNA

Carbohydrates : basic unit is monosachharides. They share glycosidic bond between each other.   

In forensics the main component if Biomolecules which gives clue is DNA. Each individuals contains a unique genes and thus unique DNA sequence.

DNA profiling or fingerprints are so important because they are unique. So it could identify the correct criminal. Also PCR or polymerase chain reaction technique is used to multiply the DNA for further investigation.

DNA fingerprints are also used as understanding parental generation or ancestors.
