Current Question (ID: 12668)

Question:

Which of the following is present in matrix of mitochondria

Options:

1. ribosomes
2. RNA
3. DNA
4. All of the above

Solution:

Ribosomes, RNA, and DNA are present in the matrix of mitochondria. Mitochondria have their own genetic material, which is in the form of circular DNA. This DNA encodes for some of the proteins that are required for the mitochondria to function. The ribosomes in the matrix help in the translation of this mitochondrial DNA into proteins. The RNA in the matrix helps in the transcription of mitochondrial DNA into RNA, which is then translated into proteins by ribosomes. The matrix of mitochondria also contains enzymes that are involved in the citric acid cycle, which is the pathway for the production of ATP in mitochondria.
