Answer:
Prokaryotic cell:
Prokaryotic cell do not have the nucleus and their DNA is present in the cytoplasm. The membrane bound cell organelle are absent in the prokaryotic cells. The ribosome of prokaryotic cell is 70'S. Transcription and translation is coupled in prokaryotic cells.
Eukaryotic cells:
Eukaryotic cell have well defined nucleus and their DNA is present inside the nucleus. The membrane bound cell organelle are present in the eukaryotic cells. The ribosome of eukaryotic cell is 80'S. Transcription and translation is not coupled and takes place in separate compartments in eukaryotic cells.
Its called osmosis and it only happens with water. now I'm just adding words to be able to post this. its moving down the concentration gradient.
True is the answer hope this helps
Microtubules are tiny, hollow, bead-like tubular structures that help cells maintain their shape. Along with microfilaments and intermediate filaments, they form the cytoskeleton of the cell, as well as participate in a variety of motor functions for the cell.
Answer: B
WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.
