How does the DNA code become a protein?
DNA has the code for a protein which mRNA has to copy and then take that copy out of the nucleus to an other organelle called a ribosome.
There the copy is translated into the protein.
These amino acids are “added” one by one to form a protein..
Where does DNA transcription occur?
In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm. In prokaryotes, the two processes are closely coupled (Figure 28.15).
What happens during translation?
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. … Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
Why is DNA called the code of life?
DNA is often referred to as the code of life because it is just that: a code containing instructions on how to build various proteins. … Other proteins work to protect and maintain the cell’s structure, move cargo around within the cell, or even help cells communicate with and signal to other cells.
What is the difference between DNA and protein?
DNA contains the genetic information of all living organisms. Proteins are large molecules made up by 20 small molecules called amino acids. All living organisms have the same 20 amino acids, but they are arranged in different ways and this determines the different function for each protein.
How is a protein made step by step?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What does DNA contain the instructions for?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Why DNA is not a code?
The names guanine, adenine, thymine and cytosine are not codes: they are primary symbols. Primary symbols stand for real things and not for symbols. The real physical entities guanine, adenine, thymine and cytosine are not codes. … To claim that computer code and DNA are both codes is an abuse of the power of words.
Are proteins created from the code in DNA?
The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health. … The cell reads the DNA code in groups of three bases. Each triplet of bases, also called a codon, specifies which amino acid? will be added next during protein synthesis.
What is the process of DNA to protein?
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.
What is a DNA code?
Genetic Code The instructions in a gene that tell the cell how to make a specific protein. A, C, G, and T are the “letters” of the DNA code; they stand for the chemicals adenine (A), cytosine (C), guanine (G), and thymine (T), respectively, that make up the nucleotide bases of DNA.
Is Protein A DNA?
When there is a change in the genetic code it is called mutation. The significance of a DNA is very high. The gene’s sequence is like language that instructs cell to manufacture a particular protein….I.a.

How is protein created?
Protein from your diet is broken down into individual amino acids which are reassembled by your ribosomes into proteins that your cells need. … The information to produce a protein is encoded in the cell’s DNA. When a protein is produced, a copy of the DNA is made (called mRNA) and this copy is transported to a ribosome.
Is DNA a cell?
Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
