Afghanistan, meanwhile, is smaller than Texas on its own. If youâre the right kind of nerd, you can probably do this forever and not get boredâcheck it out, Mexico is maybe two and a half Texases! As a frame of reference for how big parts of the world are, Texas is a pretty good one.
In fact, the actual structure of the DNA molecule and how it codes for proteins is the same from bacteria to yeast to plants and animals. The DNA molecule in plants, humans, and all living things are all the same shape -- like a twisted ladder, or a double helix.The backbone of the ladder is made up of sugar and phosphate molecules. Each rung of the ladder is made up of two bases that stick out from the backbone and pair in the middle (a base pair).he building blocks and shape of DNA molecules in humans, plants and every living thing is the same -- we all have the famous A, C, G, and T's.
RNA contains ribose, while DNA contains deoxyribose, a similar sugar that contains one fewer oxygen molecule (de...oxy). Another difference is that DNA is double-stranded, while RNA is a single strand.Three of the nitrogenous bases are the same in the two types (adenine, cytosine, and guanine), but DNA contains thymine while RNA contains uracil. There are also functional differences.DNA is the blueprint for all proteins formed by the cells.NA contains ribose, while DNA contains deoxyribose, a similar sugar that contains one fewer oxygen molecule (de...oxy). Another difference is that DNA is double-stranded, while RNA is a single strand.
