"Degenerate" refers to redundancy in the genetic code. Amino acids, the building blocks of proteins, are encoded by codons of three nucleotide bases. Some amino acids are encoded by more than one codon, for example glutamic acid (GAA and GAG). Degeneracy occurs because there are more codons than amino acids.
To answer this question, it is first important to understand the meaning of the word degenerate. So being an A level Biology student, you must know that genes code for amino acids. (these are the basic components of protiens) Now, each amino acid is coded for by a triad sequence of bases , namely Adenine, Cystine, Thyamine and Guanine (Thyamine ...
Degenerate genetic coding means that although there are 64 different codons, there are only 21 amino acids, meaning that there are multiple codons which code for one single amino acid. The advantage for this is that it although there may be a mutation in the codon, if the mutation changes the codon to another codon which codes for the same ...
There are some instances where some particular amino acids can be coded for by more than one codon (codon being three nucleotides bonded together). This is known as DNA being dengerate. If we take Valine (val) as an example, it is coded for by the codons GUU, GUC, GUA, GUG. This means that if the third nucleotide base is substituted by Adenine ...
The genetic code is universal because all species use the same four bases A,T,C and G, and each base sequence codes for the same amino acid in all species. despite the 64 possible codons (sequence of three bases), there are only 20 possible amino acids. This means that multiple codons code for one amino acid, meaning the code is degenerate.
What does this mean? and why ? We say that the genetic code is degenerate because there are several codons, which code for the same amino acid. For example UCA, UCU, UCG and UCC all code for Serine. This is due to the fact that mRNA coding for an amino acid only has 4 possible letters A, U, C and G and that there are 20 amino acids that need to ...
There are 64 codons that code for 20 amino acids. The redundancy in the genetic code refers to the fact that there are more than one variation of codon that codes for the same amino acid. This is also known as the genetic code being degenerate. The four letters (nucleotides) in our DNA code - ATGC - code for the thousands of different proteins ...
There are four levels of protein structure. The primary structure is the order of amino acids in the peptide. Secondary structure is the folding of the polypeptide chain due to hydrogen bonding into an alpha helix structure, resembling a coiled spring, or a beta pleated sheet. Tertiary structure is the 3-D folding due to ionic and disulphide ...
When the water ligands bond to the Cu2+ ion, it causes the d orbitals to split into 2 sets at different energy levels. Electrons in the lower energy d-orbitals absorb red light to promote the electrons to a higher energy d-orbital. This means blue light will be reflected and hence the colour of the complex is blue. [Cu (H2O)6]2+ is and ...
A sequence of three bases is called and codon and this represents one amino acid in the polypeptide. The genetic code is described as degenerate because often, more than one codon codes for the same amino acid. DNA is made up of sequence of nucleotides ( a phosphate, a pentose sugar and nitrogenous base). It is the sequence of bases on the DNA ...
