The process by which DNA turns into polypeptides is a complicated and long. Two main steps in changing the DNA into a polypeptide are transcription and translation‚ with transcription coming first. The process first starts in the nucleus of the cell. The DNA begins to unfold with the help of a helicase. During the transcription phase of the change‚ strands of DNA begin to unwind and the complementary mRNA is made or transcribed. The way they do this is by using the common pairs of DNA triplet bases

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized

chlorophyll‚ the pigment that gives plants their green color and allows them to perform photosynthesis. Specialized cell-to-cell communication pathways known as plasmodesmata‚[3] pores in the primary cell wall through which the plasmalemma and endoplasmic reticulum[4] of adjacent cells are continuous. The onion epidermal cell provides a protective layer against unwanted viruses that may harm the sensitive tissues. The clear epidermal cells consist of a single layer and contain chloroplasts‚ because the
