what are gene . write about mitochondria
Answers
Answer:
The mitochondrial genome contains 37 genes that encode 13 proteins, 22 tRNAs, and 2 rRNAs. The 13 mitochondrial gene-encoded proteins all instruct cells to produce protein subunits of the enzyme complexes of the oxidative phosphorylation system, which enables mitochondria to act as the powerhouses of our cells.
Answer:
❤️GENES❤️
➡️In biology, a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein.
➡️A gene is the basic physical and functional unit of heredity.
➡️Genes carry the information that determines your traits , which are features or characteristics that are passed on to you — or inherited — from your parents.
➡️Each cell in the human body contains about 25,000 to 35,000 genes.
➡️For example, there are several different alleles for eye color genes, such as blue alleles (blue eyes) and brown alleles (brown eyes).
❤️MITOCHONDRIA❤️
➡️Mitochondria are known as the powerhouses of the cell.
➡️Mitochondria are membrane-bound cell organelles that generate most of the chemical energy needed to power the cell's biochemical reactions.
➡️They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
➡️The biochemical processes of the cell are known as cellular respiration.
➡️ The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP, through respiration, and to regulate cellular metabolism.
