The sequence of nitrogen bases of the template strand of DNA in a transcription unit is 3'-ATTGAACTG-5'. The sequence of nitrogen bases in its mRNA transcript would be:

Which one of the following is known as cytokine barriers?

Find out the odd one out among the following structures in relation to evolution?

Read the following passage carefully and answer the given questions.
Restriction endonuclease on finding its specific recognition sequence, bind to the DNA and cut each of the two strands of the double helix at specific points in their sugar -phosphate backbones. Each restriction endonuclease recognises a specific palindromic nucleotide sequences in the DNA. Since the DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). Now a days the most commonly used matrix is agarose which is a natural polymer extracted from sea weeds. The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. The first restriction endonuclease-Hind II, whose functioning depended on a specific DNA nucleotide sequence was isolated and characterised five years later. It was found that Hind II always cut DNA molecules at a particular point by recognising a specific sequence of six base pairs. In addition to 'ori', the vector requires a selectable marker, which helps in identifying and eliminating non-transformants and selectively permitting the growth of the transformants. Transformation is a procedure through which a piece of DNA is introduced in a host bacterium. Normally, the genes encoding resistance to antibiotics such as ampicillin, chloramphenicol, tetracycline or kanamycin, etc., are considered useful selectable markers for E. coli.
Transformation is a procedure through which:

Identify the incorrect fact about genetic modification.

Arrange the given steps involved in gel electrophoresis used for separation of DNA fragments ?
(A) Exposure to UV light

(C) Moving of DNA fragments towards anode
(D) Elution

Elements of group-15, 16 and 17 form compounds with hydrogen with general formula MH3, H 2 M and HX (called hydrogen halides). Stability of these hydrides, along with M-H bond strength and basic nature decreases down the group. Boiling point of these hydrides mainly depends on the strength of their inter molecular forces.
Bond angle (HMH) among hydrides of group-16 decreases down the group because:
