Which of the following is not true about Eukaryotes?a)Eukaryote chromo...
Explanation:
Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. These organisms include plants, animals, fungi, and protists. Eukaryotic cells are more complex than prokaryotic cells and have several distinct features, including the presence of a nucleus and membrane-bound organelles.
a) Eukaryote chromosomes are haploid:
This statement is not true. Eukaryote chromosomes are not haploid, but they are diploid. Diploid cells contain two sets of chromosomes, one set inherited from each parent. These chromosomes are found in the nucleus of the cell and carry the genetic information necessary for the development and functioning of the organism. Haploid cells, on the other hand, contain only one set of chromosomes and are typically found in reproductive cells (gametes) such as sperm and egg cells.
b) Eukaryote chromosomes are linear in shape:
This statement is true. Eukaryote chromosomes are linear in shape, meaning they have distinct ends. The linear shape allows for efficient packaging of the genetic material within the nucleus. In contrast, prokaryotic chromosomes are typically circular.
c) Eukaryote chromosomes can be seen during the process of cell division:
This statement is true. Eukaryote chromosomes are visible during the process of cell division, specifically during the stages of mitosis and meiosis. During these processes, the chromosomes condense and become visible under a microscope. This allows for the accurate distribution of genetic material to daughter cells.
d) Eukaryote chromosomes are made of DNA:
This statement is true. Eukaryote chromosomes are made of DNA (deoxyribonucleic acid), which is a double-stranded molecule that carries the genetic information in the form of genes. DNA is organized into structures called chromosomes, which are tightly coiled and condensed during cell division.
Conclusion:
The statement that is not true about eukaryotes is option 'a', which states that eukaryote chromosomes are haploid. In reality, eukaryote chromosomes are diploid, meaning they contain two sets of chromosomes.
