The answer is ribose.
mRNA is actually messenger ribonucleic acid. As any other RNA (ribonucleic acid) it consists of a phosphate group, sugar ribose, and nucleobases (adenine, uracil, cytosine, guanine). So, it is called RIBOnucleic acid because it consists of sugar RIBOSE.
Take for example DNA - deoxyribonucleic acid. It is called DEOXYRIBOnucleic acid because it consists of sugar DEOXYRIBOSE.
Properties of solids: Properties of solids
(i) Solids have definite shape and distinct boundaries.
(ii) Solids have fixed volume.
(iii) They have negligible compressibility.
(iv) They are rigid (their shape cannot be changed).
(v) Their intermolecular force of attraction is maximum.
(vi) The kinetic energy of its particles is minimum.
Properties of liquids: Properties of liquids
(i) Liquids do not have definite shape and distinct boundaries.
(ii) Liquids have fixed volume.
(iii) They can be compressed.
(iv) They take up the shape of the container (they can change its shape).
(v) They are fluid and thus can flow like water.
(vi) Their intermolecular force of attraction is less than solids.
(vii)The kinetic energy of its particles is more than solids.
Properties of gas: Properties of gas
(i) Gases neither have definite shape nor have fixed volume.
(ii) They can be compressed much.
(iii) They can take any shape.
(iv) They are neither rigid nor fluids.
(v) Their intermolecular force of attraction is least.
(vi) The kinetic energy of its particles is maximum.
