Why isn't it possible for adenine to pair up with guanine or cytosine?
Lets look at it this way: Thymine and adenine are pieces of a jigsaw puzzle that matches. Cytosine and Guanine are also pieces of jigsaw puzzle that matches. A cytosine cannot match with thymine because the shape of cytosine will only match with the shape of a guanine. To look at it in another way: Thymine(uracil in RNA) and cytosine are pyrimidines. Pyrimidines are single-ringed organic base that will only attach to purines, or adenine and guanine by hydrogen bond. Because cytosine and thymine are both pyrimidines, it cannot form a hydrogen bond with each other.
How many different shapes are there?
There are many geometric shapes but if you count the organic ones there is billons.
A strand of dna contains the base sequence agtt what is the sequence of the complementary strand of dna?
TCAGCC A (Adenine) pairs with T (Thymine), and C (Cytosine) pairs with G (Guanine.) This is due to the shapes for the four molecules, which make it possible for them to form Hydrogen bonds (which holds the two strands of DNA together) with only one of the other three base molecules.
How many different shapes of volcanoes are there?

Why is it necessary for cells to be different shapes and sizes?
If they were the same shapes and sizes then life would be exceedingly boring.
How are the four nucleotides different?
A nucleotide is composed of a nucleobase (nitrogenous base), a five-carbon sugar , and one phosphate group.They differ in their nitrogenous bases - they can either contain a purine(big) or a pyrimidine(small) base. In DNA, the purine bases are adenine and guanine, while the pyrimidines are thymine and cytosine. RNA uses uracil in place of thymine

Why are shapes and sizes of cell different?
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
How are areas of regular shapes calculated?
There are different formulae for different shapes.
What is two shapes that are different sizes called?
If they are the same shapes but differ only in size, then they are SIMILAR shapes. Otherwise, they are simply different shapes.
Why clouds forms different shapes?
because the wind blows them into different shapes. :)
Can two shapes have the same perimeter?
Yes - even shapes with different area.
How do plant cells have different shapes?
To perform different functions plant cells assume different shapes
Why do shells have different shapes and sizes?
This is because the animals which live in them have different shapes and sizes.
Can different shapes have the same Volume?
Yes many different shapes can have the same volume
How are organic shapes different from geomictric shapes?
Organic shapes are shapes with a natural look and a flowing and curving appearance.
How many shapes can a moon have?
the moon can have up to 8 different shapes so there are different kinds of shapes and you rarely see a full moon
