In symbiotic mode of nutrition both organism are benefited while in parasitic mode only one organism get benefits.
Answer:
DNA molecular weight standard controls, also known as DNA ladders
Explanation:
A DNA ladder is a molecular-weight size marker used to identify the size of the PCR products in a gel electrophoresis. The DNA ladder consists of a solution containing double-stranded DNA fragments with different molecular weights including, among others, 50 base pairs (bp), 100 bp, 1000 bp and 3000 bp DNA fragments. The concentration of each DNA fragment in the DNA ladder must be sufficiently high to be visualized on the electrophoresis gel.
enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
Answer:
Rubella.
Explanation:
German measles is a viral infection that causes red rashes on the whole body of an infected person. The disease can be easily spread from infected people to healthy people by sneezing or coughing.
The German measles is caused by rubella virus.Rubella virus contains single stranded DNA as its genetic material. Rubella virus causes fever and swollen lymph nodes in infected individuals.
Thus, the correct answer is rubella virus.
