1) the structure of a protein molecule is held together by covalent bonds such as peptide bonds, which are made during the process of protein biosynthesis.
2) a biological process that allows individual cells to build specific proteins
3) rna is a nucleic acid present in all living cells. the associate with a set of proteins to form ribosomes which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. the also bind and various accessory molecules needed for protein synthesis.
4) 1) messenger RNA is translated into protein by the joint action to transfer RNA and the ribosome, which is composed of numerous proteins and two ribosomal RNA molecules 2) Ribosomal RNA associated with a set of proteins to form ribosomes.
I hope this helps with the first few!!
