Why is Luster not a good characteristic to use for the identification of minerals?

Biology

Gnesinka [82]3 years ago
7 0
Luster means to give shine to a surface. Luster is a general idea of a mineral but you may need to be more specific. By specific I mean what kind of luster does the mineral have? Metallic, Non-Metallic, Vitreous, Resinous, Pearly, Greasy, Silky, or Adamantine. These are more specific types of luster than just saying luster.

ad-work [718]

Answer:

The complete set of an organism's or population's genes. B. genome

A variation at a single position in a DNA sequence among individuals of the same species. F. single nucleotide polymorphism (SNP)

A lab instrument used to precisely measure and move small amounts of liquid. E. micropipette

A procedure that makes thousands of copies from a small sample of DNA. J. polymerase chain reaction (PCR)

A word that means to copy. I. amplify

An enzyme that copies a single strand of DNA. A. DNA polymerase  

A single, short piece of DNA that must be present to copy a DNA template. D. primer  

Viruses that infect bacteria. C. bacteriophages  

Short enzymes that cut DNA samples at a specific base sequence. H. restriction endonucleases (restriction enzymes).

A process that separates pieces of DNA by their size using an electrical current. K. gel electrophoresis

A series of chemical reactions that generate a cellular response. L. signal transduction

A molecule that binds to another molecule. G. ligand  

Explanation:

Genome is also defined as a full set of genetic material in an organism.

SNP is usually referred to a substitution of a single nucleotide at a specific position in the DNA.

Micropipette is used for the precise measurement and for the exact amount of liquid delivery.

PCR is a widely used technique in molecular biology, used for the amplification (replication) of DNA fragments. It is performed thanks to heat-resistant enzyme (Taq polymerase) through the cyclic reactions. Polymerases are enzymes that add nucleotides in order to make chanis-polymers of nucleic acid (polymerization) and they require short DNA segment (primer) in order to start the polymerization. Restriction enzymes are enzymes that recognize and cut DNA at specific site (restriction site) and are widely used in DNA cloning.

Signal transduction is a set of steps from signal binding to cell response that are transmitted through the cell. It usually starts with ligand-receptor binding.
