Cytoplasm short note

WebCytoplasm is the ground substance present between plasma membrane and nucleus of all cells excepting viral cells. It is an amorphous, translucent, homogenous, colloidal substance, differentiated into cytoplasmic matrix and cytoplasmic structures. WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.
