What are the functions of the different types of rna in protein synthesis. i need a paragraph, pls will give !

First you have the mRNA or the messenger RNA. They are responsible for delivering the code from the DNA in the nucleus, to the ribosomes, where proteins are synthesized. The next would be the rRNA or the ribosomal RNA which are found in the ribosomes. They help with translation, or amino acid assembly. They bind with the next type of RNA, which is the tRNA. The transfer RNA or the tRNA carry the amino acids to the template from the mRNA. Each tRNA have a specific amino acid on them and they act as an adapter, between the mRNA code and the amino acid it carries. It translates the mRNA code to amino acid, to form the protein specific to the instructions of the DNA.  

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

so whats the answer
