A molecule that has a negative and positive end is a polar molecule.
The hydrophilic head which is made up of a phosphate group and a polar molecule.
To my knowledge, it is a polar molecule. Hope this helps, let me know if I'm wrong :)
In the context of chemistry, a dipole is a polar molecule, having a negatively charged end and a positively charged end, as a result of the specific geometry of the electron configuration of that molecule. The poles of a given molecule then interact with other poles of other molecules on the basis of Coulomb's Law. Like poles repel, opposite poles attract.
Transfer RNA is an inverted "L" shaped molecule. Each tRNA recognizes only one specific amino acid, which becomes attached to the 3'-hydroxyl end (the tail or top of the inverted "L") of the molecule. On the opposite end of the molecule are 3 nitrogen bases called an anticodon triplet, which pair up with messenger RNA codons during translation.
"polar"
Such a molecule is said to have an electric dipole.
each end has opposite, partial charge
the ends of the water molecule have opposite electrical charges
The anticodon is on one end of a tRNA molecule while an amino acid is on the other.
A polar molecule doesn't necessarily have any overall charge. All polar means is that one part of the molecule has a negative charge and another part of the same molecule has a positive charge. These charges balance. When the charges don't balance and there is a net charge, it is referred to as an ion. An example of a polar molecule is fluoro-methane, or CH3F. The fluorine attracts the electrons in the bond a lot harder than carbon. so the fluorine has a negative charge while the carbon atom ends up with a positive charge.
The DNA molecule is anti-parallel. This is because the two strands are the opposite of one another, such that if one strand has the base sequence ATC, the opposite strand would have the base sequence TAG.
A molecule that has a negative and positive end is a polar molecule.
Polaric molecule
A polar molecule such as water
The hydrophilic head which is made up of a phosphate group and a polar molecule.
yes. the positive end of the molecule attracts the negative end of the adjacent molecule
