Ovary wall is absent
Integuments are absent
Perianth is absen
Nucellus is absent
The rupture and fractionation do not usually occur in the water column in vessel/tracheids during the ascent of sap because of
Lignified thick walls
Cohesion and adhesion
Weak gravitational pull
Transpiration pull
Gel electrophoresis is used for
Cutting of DNA into fragments
Separation of DNA fragments according to their size
Construction of recombinant DNA by joining with cloning vectors
Isolation of DNA molecule
Polysome is formed by
Several ribosomes attached to a single mRNA
Many ribosomes attached to a strand of endoplasmic reticulum
A ribosome with several sub-units
Ribosomes attached to each other in a linear arrangement

Tiger reserve
Biosphere reserves are a special category of protected areas of land and/ or coastal environments wherein people are an integral component of the ecosystem. It represents a specified area zoned for a particular activity and consists of core one with limited human activities and manipulation zone with several manipulating human activities.
