Short sequence of amino acids. Insulin is a polypeptide of about 53 [amino-acid] residues; it is like Pluto - is it a protein or not?
If the amino acids in an insulin molecule were assembled in a different order, it would result in a different sequence of amino acids. This would change the structure and function of the insulin molecule, potentially rendering it ineffective in regulating blood sugar levels. Incorrect assembly of amino acids could also result in a misfolded protein that may be dysfunctional or unable to perform its specific role in the body.
A polypeptide is a chain of amino acids linked together by peptide bonds. It is not a sequence of proteins, but rather a precursor to protein formation. When a polypeptide chain folds into a specific structure, it becomes a functional protein.
Amino acid sequence primarily determines a proteins shape, but secondary (alpha helix and beta sheet) and tertiary structures (Hydrogen bonding, other chemical bonding between structures) adds to it.
Each codon codes for a specific amino acid, which is a building block of proteins. The sequence of codons in mRNA determines the sequence of amino acids in a protein. There are 64 possible codons, with 61 coding for amino acids and 3 serving as stop codons to signal the end of protein synthesis.
called coding sequences or exons. These sequences are transcribed into messenger RNA (mRNA) and eventually translated into a specific sequence of amino acids to form a protein.

There are 20 different amino acids in the DNA sequence
No, they code for amino acids (in sequence).

To determine how many amino acids are coded for in the segment 5' atcagcgctggc 3', we first need to convert the DNA sequence into its corresponding mRNA sequence. The mRNA sequence would be 5' UAG UCG CUG CCG 3'. Each amino acid is coded for by a codon, which consists of three nucleotides. Therefore, this mRNA sequence contains four codons, coding for four amino acids.
Transcription.
Amino acid sequence primarily determines a proteins shape, but secondary (alpha helix and beta sheet) and tertiary structures (Hydrogen bonding, other chemical bonding between structures) adds to it.
A gene coding for a polypeptide made of 51 amino acids would have (51 \times 3 = 153) bases. Each amino acid is coded by a sequence of three nucleotide bases in mRNA called a codon. So, the number of bases required to code for a polypeptide can be calculated by multiplying the number of amino acids by 3.
Each codon codes for a specific amino acid, which is a building block of proteins. The sequence of codons in mRNA determines the sequence of amino acids in a protein. There are 64 possible codons, with 61 coding for amino acids and 3 serving as stop codons to signal the end of protein synthesis.
mRNA has the codon sequence that exactly correspond to the amino acid sequence. The DNA has two strands. Though one of the strands (coding strand) carries the same information as on the mRNA, it contains unspliced introns that will mess up the amino acid sequence.
