(i) The non-coding sequence of DNA that are repeated several times in the genome of an individual are termed as repetitive DNA sequences. Whereas satellite DNA is one of the various categories of repetitive DNA sequences that contain highly repetitive DNA. Depending upon the number of repeats, satellite DNA is grouped as minisatellites, microsatellites, and minivariant repeats. 

(ii) Messenger RNAs (mRNAs) specify the amino acid sequence of one or more polypeptides, thus it transfers genetic information from DNA to ribosomes. Whereas transfer RNAs (tRNAs) read the genetic information present in form of triplets in the mRNA and transfer the appropriate amino acid from amino acid pool of cytoplasm to a growing polypeptide chain during protein synthesis.
