This option is correct because CD 8 is a transmembrane glycoprotein present in suppressor T cells.

Zymography is a electrophoretic technique for the detection of hydrolytic enzymes, based on the substrate repertoire of the enzyme.

Chlorotrianisene is a non-steroidal synthetic oestrogen that was formerly used for the treatment of menopause, deficiencies in ovary function, and prostate cancer.
Diethylstilbestrol is a synthetic nonsteroidal oestrogen that was first synthesized in 1938.
Fosfestrol is a synthetic oestrogen used as an antineoplastic agent.

Basic Local Alignment Search Tool (BLAST) is an algorithm for comparing primary biological sequence information.

Type II restriction enzymes usually require Mg²⁺ as a cofactor ion for their activity.

Chaperones are a functionally related group of proteins assisting proper protein folding in the cell under physiological and stress conditions.
Prions are proteins that are unique in their ability to reproduce on their own and become infectious.

2,4-Dichlorophenoxyacetic acid (2,4-D) is a common systemic pesticide/herbicide used in the control of broadleaf weeds. It is one of the most widely used herbicides in the world and is the third most commonly used herbicide in North America. 2,4-D is a synthetic auxin (plant hormone).
2,4,5-Trichlorophenoxyacetic acid (2,4,5-T), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants.

Correct answer.
In the cell cycle, replication of the genome occurs in the S phase.
During C phase, a cleavage furrow is formed in animal cells.
G1 is the primary growth phase of a cell.
The spindle forms in the M phase.

Micro biosensors can be integrated on one chip and are useful for measuring various substrates in a small amount of sample solution simultaneously.
It is possible to develop disposable transducers for biosensors through mass production.

Rifamycin inhibits bacterial DNA-dependent RNA synthesis by inhibiting bacterial DNA-dependent RNA polymerase.

Random amplified polymorphic DNA (RAPD) is a method that reveals intra-specific variation and diversity between species.

Glycerate 3-phosphate acts as a precursor for serine which in turn, can act as precursor to create cysteine and glycine through the homocysteine cycle.

Explant is any portion taken from a plant that will be used to initiate a culture.
Probe is a fragment of DNA or RNA which is used for hybridization.
Restriction endonucleases are molecular scissors that recognize short DNA sequences, usually 4–8 bp in length and cut the phosphodiester bond within or close to their target sites to generate a double-stranded break.
Ligases are called 'molecular stitchers' because of their ability to catalyse the joining of two large molecules by forming a new chemical bond.

The ability of the component cells of callus to form a whole plant is known as redifferentiation.

Ciprofloxacin, Ofloxacin, Metronidazole: All inhibit bacterial DNA synthesis
