The enzyme responsible for facilitating hydrogen bonding between nucleotides in a new DNA molecule is Polymerase.
Answer:
The provided question is incomplete as there is no option available however the generalized answer would be -
The correct answer would be - For treating the global symptoms related to the allergies, it is known as that the inhaled nasal steroids are far more effective than oral medications.
Explanation:
Nasal steroids are the steroids that relieve congestion problems by decreasing the inflammation in the nose of an individual. These are then inhaled by the nose which directly sprays into nasal passages.
In comparatively the oral steroids take time to show their impact on the individual and even the impact is considered not as effective as the inhaled nasal sprays.
Thus, the correct answer is - For treating the global symptoms related to the allergies, it is known that inhaled nasal steroids are far more effective than oral medications.
The frontal lobe takes about 1/3 of the cerebral cortex.
Answer:
The correct answer will be option-B
Explanation:
cDNA library or complementary library is the DNA library constructed from the mRNA which is isolated from the specific tissue.
The genomic library is constructed from the genome sequence of the organism by cutting the gene of interest or the whole genome with a restriction endonuclease and then inserting it into the vectors.
Since the genomic library includes the whole genome which is same in every cell and tissue whereas the cDNA library contains the coding genes expressed in the specific tissue only therefore, Option-B is the correct answer.
Answer:
Options I and II
Explanation:
Evolution refers to the changes that occurs in the morphology, appearance and behavior of an organism over a due course of time. This changes occurs due to the natural selection method, where organisms undergoes changes and adapts to the newly habitable environment.
The above given options I and II are the evidences of evolution. The similarities in terms of bones and their defined structure between the bat wings and porpoise fins are signs of evolution that has taken place over a definite span of time. Also, the changes in the various breeds of dog that are caused by the artificial selection method is also an example of evolution.
Thus, the correct answers are options I and II.
