Complementary Sequence to its corresponding mRNA and the mRNA
Antisense RNAs are utilized for gene regulation and specifically target mRNA molecules that are used for protein synthesis.
<h3>What is the function of Antisense Gene ?</h3>
Antisense RNAs play the crucial role in regulating gene expression at multiple levels, such as at replication, transcription, and translation.
- In addition, artificial antisense RNAs can effectively regulate the expression of related genes in host cells.
- Antisense gene therapy is a gene silencing technique similar to RNA interference, but uses a slightly different mechanism.
- The therapy is called a gene silencing technique because, instead of repairing the gene, it aims to “silence” the gene's effect.

Answer:
Transpiration:
Losing the water absorbed by the plant through its aerial parts in the form of water vapor to the atmosphere. Water is absorbed by roots from the soil and transported as a liquid to the leaves via the xylem to mesophyll cells, through intercellular spaces, and moving through substomatal space to the stoma. The leaves and aerial parts have small pores that allow water to moves as a vapor.
Advantages:
With the transpiration exchange of gases also takes place.
Excess amount of water removed from the plant body.
Absorbing water and distribution of water among plant body parts
Cooling the exposed aerial parts of the plant to the sun and warm winds.
The osmotic balance of the plant cell is regulated by the process of transpiration.
The logical sequence in order to loss of water due to transpiration is as follows:
xylem, mesophyll cells, intercellular spaces, substomatal space, stoma.
1) variation in traits.
population of beetles: equal brown and green numbers in population.
2) differential reproduction.
Natural habitat is in trees. Green leaves hide green beetles.
The brown beetles are noticed by birds in the area.
Birds eat brown beetles.
More green beetles survive than brown beetles
3) heredity
Green beetles reproduce in greater numbers than brown beetles
4) end result
Beetle population changes from brown and green to mostly green beetles.
