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.
A human cell has genetic material contained in the cell nucleus (the nuclear genome) and in the mitochondria (the mitochondrial genome). In humans the nuclear genome is divided into 46 linear DNA molecules called chromosomes, including 22 homologous chromosome pairs and a pair of sex chromosomes. The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated with histone proteins. 2  All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. 3  Some eukaryotic organelles such as mitochondria also contain some DNA.
