D. genus Species
Answer : The correct answer for the blank is -
Producing spores.
Fungi is a separate kingdom of multicellular eukaryotic organisms that are different from plants and animals.
By asexual reproduction, they produce large number of genetically identical, haploid reproductive cells, called spores.
Spores are spread through wind and under favourable conditions, they germinate to form new fungi.
Thus, producing spores is the right answer.
B) Nucleoli are large protein complexes that cross the nuclear envelope in eukaryotic cells.
C) Nucleoli are thin, dense meshworks of fibers lining the inner surfaces of the inner nuclear membranes of most eukaryotic cells.
D) Nucleoli are structures made of DNA, RNA, and protein that are present in the eukaryotic nucleus.
Answer:
Option-D
Explanation:
The nucleolus is a structure present in the nucleus of the cell which is important for the cell.
The nucleolus provides the site of transcription of the rRNA genes and the enzymes required for transcription. The nucleoli appear condensed structure as the rRNA genes, some portion of DNA and the proteins in the form of the enzymes like RNA polymerase I.Therefore, nucleoli are made of the DNA, RNA and the proteins.
Thus, Option-D is correct.
Answer: Option D
Explanation:
The nucleolus is the largest structure which is found in the nucleus of the eukaryotic cells. It is the main site for the ribosome biogenesis.
Nucleoli consists of DNA and RNA, proteins and it forms around the nucleolar organizing regions. it also help in cell signaling.
These are like envelops which bounds the nucleus inside it. In case of the treatment of cancer, the main target is nucleolus.
