3. Nucleus in Eukaryotes: - Eukaryotic cells possess a true nucleus that is enclosed by a double-layered nuclear membrane (also known as the nuclear envelope). - This nuclear envelope separates the contents of the nucleus from the cytoplasm, providing a distinct environment for the DNA and asso...
What separates the nucleus from the cytoplasm? Explain how the structures of the organelle involved in protein synthesis and the organelle which controls the activities of the other organelles in the cell, relate to their functions. What is the main function of the nucleus? What organelles are un...
Which plasma protein is a major contributor to the osmotic pressure of plasma? A) translipin B) steroid-binding protein C) hormone-binding protein D) albumin E) gamma globulin The plasma membrane separates the ___ from the ___. What molecule...
The mRNA then exits the nucleus, and translation occurs in the cell’s cytoplasm. What are the key differences between prokaryotes and eukaryotes?Prokaryotes and eukaryotes vary in several important ways - these differences include structural variation - whether a nucleus is present or ...
The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process of cell division. ...
the long axis of the chromosomes, the centromere separates the chromosome into arms. The centromere, its name notwithstanding, is not usually found in the middle of the chromosome, but toward one end. This gives a replicated chromosome the appearance of an asymmetrical letter X. (The centromere...
The cytoplasm has a liquid portion. What is it called? The Cell Cytoplasm: A eukaryotic cell is comprised of membrane-bound organelles, such as the mitochondria, Golgi apparatus, endoplasmic reticulum, etc. Furthermore, it contains a nucleus, as well as a cytoplasm. The cytoplasm contains a ...
During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. ... As metaphase continues, the cells partition into the two daughter cells. What happens during prophase I? During prophase I, homologous chromosomes pair and form synapses, a step unique to ...
It controls the movement of substances in and out of the cells. It separates the cell from the external environment. The cell membrane is present in all the cells. The cell membrane is the outer covering of a cell within which all other organelles, such as the cytoplasm and nucleus, are ...
Which of the following occurs in the cytoplasm? A. Transcription B. Translation Which of the following options is correct? Transcription occurs when. a. a messenger RNA molecule is synthesized from DNA in the nucleus. b. enzymes are bound to their substrates to prod...
