Group of answer choices Poly(A) Polymerase RNA Polymerase I RNA Polymerase II RNA Polymerase III What role does TFIID play in transcription? Group of answer choices TFIID binds to the terminator sequence to stop transcription. TFIID acts as a regulatory kinase and helicase. TFIID prevents RNA polymerase II from associating with non-promoter sequences. TFIID binds to the INR and DPE sequences to distort the promoter sequences.
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
