Question

Animal cell lacking nuclei would also lack in

• A. Chromosome.
• B. Ribosome
• C. Lysosome.
• D. Endoplasmic Reticulum.

Answer 1

The correct option is A

Chromosome.

The correct option is A.

Explanation for the correct option:

1. Animal cells without nuclei would likewise be devoid of ‘Chromosome.’
2. A non-dividing cell's nucleus contains chromatin, which is the uncoiled thread-like substance that makes up a chromosome.
3. A DNA molecule and nearly equal amounts of basic histone proteins make up chromatin.
4. Histone proteins come in the shape of octamers.
5. Chromosomes are generated by the coiling and folding of chromatin during cell division during the metaphase period.
6. If an animal cell doesn't have a nucleus, it also doesn't have chromosomes.

Explanation for the incorrect options:

Option B:

1. The ribosome is a complex molecule made up of ribosomal RNA molecules and proteins that functions as a factory in cells to produce proteins.
2. In 1955, George E. Palade discovered it.

Option C:

1. A lysosome is a membrane-bound cell organelle that houses digestive enzymes called lysozyme.
2. Lysosomes are in charge of removing cellular detritus, as well as dead and diseased cells.
3. They can also be used to kill viruses and bacteria that have infiltrated the system.

Option D:

1. A eukaryotic cell's cytoplasm contains a large network of membranous tubules known as the endoplasmic reticulum. It is located near the nuclear membrane.
2. There are two types of it:
   1. Rough Endoplasmic Reticulum- It is involved in protein synthesis and has ribosomes linked to it.
   2. The Smooth Endoplasmic Reticulum is involved in the production of lipids.

Final answer: Animal cells lacking nuclei would also lack Chromosomes.
