during transcription, the DNA template strand is used a pattern for building a molecule of mRNA. The mRNA molecule leaves the nucleus and attaches to a ribosome. During translation, the ribosomes use the sequence of nitrogenous bases contained in the mRNA as code for assembling a chain of amino acids. Several of the polypeptide chains are combined to form a protein.

Different amino acids have different polarities. The change in the amino acid sequence thus causes a change in the overall shape of the protein. Since structure largely determines function, the changed protein doesn’t function correctly.

Detailed explanation-1: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
Detailed explanation-2: -During cellular processes known as transcription and translation, the DNA code is read, transferred into a copy called mRNA, and then the copy is read to create specific amino acids bonded together. The amino acids and their interactions create the specific shapes of proteins.
Detailed explanation-3: -The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
Detailed explanation-4: -Protein synthesis(translation) is the production of a polymer of a chain of amino acids which produces a functioning protein. It involves reading the information from mRNA (messenger RNA) to put together a chain of amino acids. Ribosomes are the structures that synthesize the protein chain.
