The rose family is a medium-sized family of flowering plants. The rose family (Rosaceae) is one of the major angiosperm families. The leaves are generally arranged spirally. Flowers of plants in the rose family are generally described as "showy". They are actinomorphic and almost always hermaphroditic.  Rosaceae generally have five sepals, and five petals. They also have many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a  cup-like structure called a hypanthium. They can be arranged in racemes, spikes, or heads; solitary flowers are rare.

DNA  is made up of deoxyribose sugar  while mRNa is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double stranded while mRNA is single stranded.
Hope this is helped ;)
