Answer: The correct answer is- Polymerase chain reaction.
Polymerase chain reaction is a technique in molecular biology that is used to produce multiple copies of a piece of DNA molecule through multiple cycles of three stages that are-
1) Denaturation- The two DNA strands are separated ( so that template DNA are exposed) at higher temperature.
2) Annealing- Primers ( forward and reverse) are attached to the template DNA.
3) Extension- New DNA strand is synthesized using enzyme Taq polymerase that adds dNTPs ( deoxyribonucleoside triphosphate) according to the complementary sequences in the template.
Answer:
Inversion.
Explanation:
Chromosomal mutation may be defined as the mutation that change the structure of the chromosome and may alter its number. Different types of chromosomal aberration are deletion, duplication, inversion and translocation.
The chromosomal inversion is the chromosomal rearrangement or the chromosome segment may get reversed. The fragment chromosome gets break off and then the segment gets join to the original chromosome but in the reverse condition.
Thus, the answer is inversion.
This is because cellulose is composed of beta glucose units, unlike starch that is formed using alpha-glucose units. The beta acetal linkage between units allows for linear chains hence branches are unlikely. The alpha acetal linkages allow for spiral chains. The beta glucose is good for structural polysaccharides because it allow for best interaction between polymer chains and increases the integrity and strength of the cells wall.
Peripheral. This connects to the central nervous system but detects signals from the sensory organs such as the eyes.
Answer:
When the Moon is positioned between the Sun and the Earth.
Explanation:
This is because you add both the gravitational pull of the Moon, with the gravitational pull of the sun.
