Answer:
The correct answer is -3' AUG CUA AUC 5'.
Explanation:
Transcription is the process in which the particular DNA segment is copied into an RNA or mRNA segment. This process involves an RNA polymerase enzyme that helps in copying the information encoded in the DNA sequences into complementary base sequences. A into U, T into A, C into G and G into C,
The DNA segment: 5'-TAC GAT TAG-3'
Th RNA segment : 3' AUG CUA AUC 5'.
Natural selection could not occur without environment, and a act on animal.
Answer:
The correct answer will be option-B.
Explanation:
The plant tissues are composed of three types of cells: parenchyma, collenchyma and sclerenchyma.
The parenchyma and collenchyma remain alive at their maturity but sclerenchyma loses their protoplasm and become dead. These cells deposit lignin in their secondary walls and form hard tissues of the plant-like hard shell of a coconut. Sclerenchyma provides mechanical strength to the plant.
Thus, Option-B is the correct answer.
