Transcription

Give one word for the following. a. Genes that are constantly requires for cellular activities. b. Sequences of nitrogen bases in mRNA containing the information for protein synthesis. c. Transcription of DNA from RNA d. A segment of DNA e. Synthesis of DNA from pre-existing DNA. f. Small genetic unit that can mutate

During the eukaryotic transcription, the genetic information encoded in the DNA will be transferred to m-RNA. The m-RNA thus formed will be processed and utilized to synthesize a protein. a. Both the DNA strands are not copied during transcription. Why? b. What do template and coding DNA strands represent? c. What will be the result, if RNA is not spliced before translation?
