What happens during the initiation step of dna transcription?

What happens during the termination step of DNA transcription? 1 The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand. 2 RNA polymerase moves along the template strand of the DNA creating an mRNA strand. 3 A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble. 4 A ribosome attaches to the initiation codon of a completed mRNA strand.

Which situations involve a cell using endocytosis? 1 A cell wraps a portion of its membrane around a droplet of nutrient-rich water and brings the droplet inside the cell . 2 A white blood cell engulfs a bacterium, brings the bacterium inside the cell, and uses digestive enzymes to destroy the bacterium. 3 Protein molecules used as hormones are disgorged through the cell membrane of the cell in which they were manufactured. 4 LDL cholesterol attaches to cell membrane proteins, triggering the membrane to fold around the cholesterol and bring it into the cell. 5 Water moves across a cell membrane and into a cell through specialized protein tunnels in response to a concentration gradient.

Answer

Ans 1) The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand. Ans 2) A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

Ans 3)  A cell wraps a portion of its membrane around a droplet of nutrient-rich water and brings the droplet inside the cell
