Converting messenger RNA, mRNA into a sequence of amino acids that make up protein is called translation.
Ribosomes
Peptide sequence or amino acid sequence is the order in which amino acid residues, connected by peptide bonds, lie in the chain in peptides and proteins. The sequence is generally reported from the N-terminal end containing free amino group to the C-terminal end containing free carboxyl group. Peptide sequence is often called protein sequence if it represents the primary structure of a protein.
Cells can synthesize specific proteins because the sequence of nucleotide bases in the DNA of genes specifies a particular sequence of amino acid building blocks of a protein molecule. This correspondence of gene and protein building block sequence is called the genetic code.
Let's consider a simple example: protein-coding genes. Mutations, or changes in the DNA sequence of the gene, can alter the amino acid sequence of the protein it codes for, if the new sequence translates into different amino acids. Because the genetic code is degenerate, some amino acids are specified by multiple codons, so some mutations may not alter the amino acid sequence at all. Such mutations, called synonymousmutations, have no affect on the protein. Mutations that alter the amino-acid sequence of the protein, called non-synonymousmutations, may or may not have an affect. Most proteins can tolerate some changes to that sequence and not be significantly affected, but if the sequence change is large enough, or occurs at a critical point so that the structure of the protein is significantly altered, then the protein may become non-functional. If that protein is essential to an organism, such a mutation may be lethal.

The intermediate molecule formed between DNA and protein is mRNA (messenger RNA). The process in which the DNA sequence is copied to an RNA sequence is called transcription. The process in which the mRNA template is read to produce protein is called translation (protein synthesis)
Primary structure of a protein represents the sequence of the amino acids of that particular protein. The amino acids are bonded together by a bond called 'peptide bond'. The peptide bond is formed by carbonyl group of an amino acid with nitrogen group of the adjacent amino acid. Only this peptide bond is responsible for the formation of primary structure of protein. Hence the ionic bonds are not involved in the primary structures of protein.
Inside a lung cell is cytoplasm and inside that are things called ribosomes. These are the things that synthesize proteins or manufacture proteins which go into the mucus.HOPE THIS HELPS!
RNA does not become protein. Messenger RNA transcribes the DNA code and carries it to a ribosome where it is translated by transfer RNA into a sequence of amino acids that will make a protein. The entire process is called protein synthesis.
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.

Yes, DNA carries the instructions for the correct sequence of nucleic acids in a protein. These instructions are encoded in the DNA molecule as a specific sequence of nucleotide bases (adenine, thymine, cytosine, and guanine). Through a process called transcription, the DNA sequence is transcribed into a messenger RNA (mRNA) molecule, which is then translated into a specific sequence of amino acids to form a protein.
