In a way, size does not effect a planet's gravity, its mass does. The more mass a planet has, the stronger its gravitational force.     But the surface gravit â¦ y is affected by the radius of the planet. That's because it depends on the distance of the surface from the center of the planet.
Which organelles contain DNA ? Eucariotic cells contain several organelles. The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA. It is separated from the rest of the cell (cytoplasm) by a double layer of membrane. The mitochondria, which have a role in the oxidative degradation of nutrient molecules, also contain DNA, called the mitochondrial DNA. Eucariotic cells that are capable of photosynthesis contain chloroplasts with chloroplast DNA.
Eukaryotic chromosomes contain both DNA and protein tightly packed together to form Chromatin. Chromatin consists of DNA tightly coiled around histones. DNA and histone molecu â¦ les form nucleosomes. These are all part of the structure of chromosomes. Cell Biology: The Translation and Use of Protein Most people know to some extent that DNA is the foundation for life. 2  It is the code at the heart of everything that happens in an organism. 3  However, not many people know how â¦.
