Question
Chapter 5, Problem 29CONQ
Summary Introduction
To review:
The structure and organization of mitochondrial and chloroplast genome. Also, identify the length, number of genes, and number of copies of the genome.
Introduction:
Mitochondria and chloroplast are organelles that show maternal inheritance, that is, the inherited traits passed by the mother to her offspring. The mitochondrial genome is a complete genetic complement of the mitochondrion, whereas chloroplast genome is a circular DNA (deoxyribonucleic acid).
