Many chromosomes have structures called telomeres at each end. Mark all the TRUE statements about telomeres below. Mark all that apply. Select one or more: a. Telomeres protect the ends of the chromosomes b. Telomeres hold sister chromatids together after replication c. Human telomeres consist of a specific base sequence (TTAGGG) repeated about 2500 times d. Telomeres are present in all prokaryotes and eukaryotes
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.
