The tendency of motion will be towards the left so friction will oppose that motion now for least μ, frictional force should be maximum

In most eukaryotic genes, coding regions (exons) are interrupted by noncoding regions (introns). During transcription, the entire gene is copied into a pre-mRNA, which includes exons and introns. During the process of RNA splicing, introns are excised and hydrolysed before mRNA moves out of the nucleus and exons are joined to form a continuous coding sequence.

Plants in forests do not make use of all the light energy available to them ecause sunlight doesn’t fall on the leaves fully.

All plants require light energy in order to obtain energy. This energy is providing by sun known as ultimate source of energy. When sun light falls on the plants in the dense forest due to its shady branches of big trees which forms canopy.

Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides– two heavy chains and two light chains joined to form a "Y" shaped molecule. The amino acid sequence in the tips of the "Y" varies greatly among different antibodies.

Butanoic acid can be converted to butane by heating with hydriodic acid (HI) and red phosphorus (Red P).

Every coenzyme is a cofactor but every cofactor is not coenzyme. Cofactors can be classified depending on how tightly they bind to an enzyme, with loosely bound cofactors termed coenzymes and tightly bound cofactors termed prosthetic groups.

The biological role of the introduced foreign gene can be predicted or observed by studying the effects of the gene in transgenic animals. The manipulated gene can introduce a new character or may lead to the loss of a character.

The unit cell having lattice parameter, i.e. a = b ≠ c and crystal angles, i.e. α= β = 90^o and γ = 120^o, is hexagonal.

The enzyme enterokinase helps in conversion of inactive trypsinogen into active trypsin.
