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.  

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
