Answer:
Asexual reproduction is a type of reproduction that doesn’t involve gametes fusing or the change in the number of chromosomes. A spider plant is the perfect example of asexual reproduction, but when it comes to plants like that, it’s referred to a type of asexual reproduction called vegetative propagation.
Answer:
Option (c).
Explanation:
Carbohydrates may be defined as the polymers of the sugars and one of the most important biomolecule of the living organisms. Carbohydrates plays an important structural and functional role.
Carbohydrates are always present on the exoplasmic surface of the plasma membrane. The are present in the association with the proteins and lipids as glycoproteins and glycolipids. These carbohydrates acts as the signaling molecule that display information on cell surface.
Thus, the correct answer is option (c).

Answer:
A biochip or DNA chip or DNA microarray is a slide that contains the different fragments of DNA . The DNA microarray technique is used to study the expression level of various genes simultaneously. For this the researcher:
A. Attach the fragments of DNA about 500 to 5,000 bp that are produced by the controlled growth of the nucleotides by providing the narrow beam of light and synthesised by the PCR technique on to the slide in the form of dots or spots.
B. In dots, the reporter oligos or probes are attached which are used to hybridize the cDNA to the microarray. The cDNA is labeled with the fluorescent molecules called fluorophore.
C. After hybridization, the probe-target hybridization is detected by placing the washed array in the confocal fluorescence microscope which observes the pixel and helps calculate the fluorescence intensity.
