Transcription. Transcription is the name given to the process where the information in a gene in a DNA strand is transferred to an RNA molecule. The coding strand and the template strand of DNA. The important thing to realise is that the genetic information is carried on only one of the two strands of the DNA. This is known as the coding strand.
1 Sugar diffuses from the mesophyll in the leaf to the phloem cells in the vascular bundles. 2  Specialized cells called companion cells load the dissolved sugar into the sugar-conducting cells (called sieve elements) of the phloem by using cellular ATP as an energy source. - collections of similar cells that serve a specific purpose by functioning together. 2  Unlike animals, the major organs of plants (roots, stems, and leaves) are all composed of the same three tissues (epidermis, vascular tissues, and ground tissues).
Specialized cells such as blood and muscle do not normally replicate themselves, which means that when they are seriously damaged by disease or injury, they cannot replace themselves. Stem cells can also divide and produce more specialized cell types.This process is called differentiation. Stem cells from different tissues, and from different stages of development, vary in the number and types of cells that they can produce.pecialized cells such as blood and muscle do not normally replicate themselves, which means that when they are seriously damaged by disease or injury, they cannot replace themselves.
