<u>Answer:</u>
This very long molecule of DNA is called chromosome.
<u>Explanation:</u>
- Chromosome is a 'DNA molecule' that contains part or all of the genetic material of an organism.
- The 'three-dimensional genome structure' of chromosome plays a vital role in 'transcriptional regulation'.
- Prokaryotes have less sequence-based chromosome structure than eukaryotes.
- The recombination of chromosome during meiosis and successive reproduction plays a significant role in 'genetic diversity'.
- Chromosomes are normally visible under microscope during the metaphase of cell division. Chromosomes are the key elements of cell division.
Answer:
A. Dommain Eukarya- kingdom Animalia
Explanation:
In the question we're given the information that the organism is a Eukaryote which eliminates choice C. We're also told the organism reproduces sexually, since fungi reproduce asexually through spores, this eliminates choice B. Therefore leaving the answer as A. Dommain Eukarya- kingdom Animalia
