Answer:
Option (c).
Explanation:
Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and transcription factors. The transcription occurs in 5' to 3' direction.
Post trancriptional modification occurs in the RNA molecule that plays an important role in transcription as well as translation. The introns are removed from the RNA transcript and exons joined together is known as splicing. The alternative splicing occurs in which different protein isoforms are formed by the single exons.
Thus, the correct answer is option (c).
Answer:
Option D, telophase
Explanation:
Telophase is the last stage of mitosis cell division in which the duplicated genetic material gets arranged into two identical daughter cells. In generals, this phase begins once the replicated, paired chromosomes have separated and arranged themselves on two opposite sides, or poles of the cells. After this, nuclear envelope begins to form around the chromosomes. After telophase, the cell undergoes cytokinesis to divide the cytoplasm of the parental cell into two daughter cells.
Hence, option D is correct
Plant Roots. The root system of a plant constantly provides the stems and leaves with water and dissolved minerals. In order to accomplish this the roots must grow into new regions of the soil. The growth and metabolism of the plant root system is supported by the process of photosynthesis occurring in the leaves.
