Only a small proportion of the genome codes for protein sequence. These regions of protein coding sequence reside within genes and are called exons. Within the exons, a group of three bases (known as a codon) will code for one amino acid. There is some degeneracy in the code; that is, for some amino acids there is more than one codon (group of three bases) that will code for a specific amino acid (see codon table for specific translation).
What else can I help you with?
What is primary structure of a protein and what causes it?
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.
How does the sequence of DNA affect the function of a protein?
The sequence of nucleotides in DNA molecule is equivalent and is closely related to an amino acid sequence in the protein molecule. If for any reason the sequence of DNA nucleotides changes it will be reflected in amino acid sequence in the protein. Moreover, the correct sequence of amino acid in the protein will form the correct three-dimensional structure, or tertiary structure, that will confer the biological activity to protein. If a wrong amino acid is translated from a mutated gene in the DNA could change the spatial structure of the protein and therefore modify or erase its biological function.
How does one protein differ from another protein?
Proteins differ from each other in their amino acid sequence, which is determined by the genetic code. This unique sequence gives each protein its specific structure and function. Differences in amino acid sequence can result in proteins with varying functions, sizes, shapes, and interactions.
When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
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.
During protein synthesis the nucleotide sequence specifies a particular species of?
During protein synthesis, the nucleotide sequence specifies a particular species of amino acid. This is accomplished through the genetic code, where a sequence of three nucleotides (codon) corresponds to a specific amino acid. The sequence of codons ultimately determines the sequence of amino acids in a protein.
How does amino acid sequence compare?
The amino acid sequence refers to the specific order of amino acids that make up a protein. This sequence determines the protein's structure and function. Changes in the amino acid sequence can alter the protein's properties and may lead to different biological effects.
What determines the amino acid sequence in a protein?
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the mRNA, and this is determined by the sequence of nucleotide bases in the DNA.
What parts of a chromosome specify the amino acid sequence of a protein?
The gene within a chromosome contains the specific sequence of nucleotides that codes for the amino acid sequence of a protein. This gene is transcribed into messenger RNA (mRNA), which is then translated into a specific sequence of amino acids during protein synthesis.
What is primary structure of a protein and what causes it?
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.

Acid subunit of protein polymer?
The acid subunit of a protein polymer is an amino acid. Amino acids are the building blocks of proteins and consist of an amino group, a carboxyl group, and a side chain. The sequence of amino acids in a protein determines its structure and function.
Why is acid sequence of a protein of the ultumate importance?
The amino acid sequence determines the three-dimensional structure of a protein, which determines the function of the protein. If the amino acid sequence is incorrect, due to a genetic defect, the three-dimensional structure of the protein may be so disrupted as to not function properly, or not function at all.
How does one protein differ from another protein?
Proteins differ from each other in their amino acid sequence, which is determined by the genetic code. This unique sequence gives each protein its specific structure and function. Differences in amino acid sequence can result in proteins with varying functions, sizes, shapes, and interactions.

The sequence of codons ultimately determines the sequence of amino acids in a protein.
How does a DNA molecule determined the structure of a protein?
The DNA sequence will determine the amino acid sequence known as the protein's primary structure. As the protein is folded into the secondary, tertiary and quatranary structures, the amino acid molecules will determine the shape
The sequence of nucleotides in DNA specifies the sequence of what in a protein?
The sequence of nucleotides in DNA specifies the sequence of amino acids in a protein. Each set of three nucleotides, called a codon, corresponds to a specific amino acid or a signal to start or stop protein synthesis.
