Tomatoes are commonly grown from seedlings started indoors that are later transplanted into the garden. Tomato seeds are commonly planted indoors as early as 8 to 6 weeks before the average date of the last spring frost. Tomato seedlings are usually transplanted into the garden 1 to 3 weeks after the last frost. Wash tomatoes under cool running water.
Slice an "X" on the bottom of each tomato with a small utility knife. In a large saucepan bring water to a rolling boil. Fill a large mixing bowl with ice cold water. With a large spoon, place tomatoes in boiling water for 30 seconds to loosen skin. Remove tomatoes after 30 seconds, place directly into cold water to stop the cooking process. Core the tomatoes by removing the stem with a paring knife. Peel away the skin, being careful not to injure the flesh of the tomatoes.
Cyclin-dependent kinases (Cdks), along with cyclins, are major control switches at these checkpoints. They are central to cell cycle control; their activation via cyclin mediates progression through all four phases of the cell cycle. p53 is a protein that functions to block the cell cycle if the DNA is damaged

Similarities in DNA
All species in the world share some amount of DNA. Species that are more related to each other share bigger amount of DNA than species that are less related. For example fruit fly and modern humans share 61% of their genome and chimps and humans share 96%.
Evolution of the eye
The PAX6 gene controls where eyes develop in animals ranging from fruit flies, octopuses, to mice and humans.
