The number of codons possible is more than the number of amino acids. This means there is redundancy in the genetic code for multiple codons to translate for one amino acid. In most cases, the first two codons dictate the amino acid while the third position is the wobble position is less important for the amino acid that is incorporated.

The genetic code refers to mRNA transcripts translated into amino acids to make proteins. This occurs due to the nucleotide triplets called codons that code for amino acids.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

Redundancy in the Genetic Code

• DNA is the hereditary material of the cell  
• It is mostly formed in antiparallel DNA strands in a double helix with a 5' and 3' end. 

• DNA contains major and minor grooves. 

• DNA is formed from hydrogen bonds between the base pairs adenine and thymine and cytosine and guanine bases, respectively.

Deoxyribonucleic Acid (DNA)

RNA is involved in protein synthesis and regulation. It also has catalytic properties.
RNA is typically found in the single stranded form.
RNA is formed from hydrogen bonds between the base pairs adenine and uracil and cytosine and guanine bases, respectively.

Ribonucleic Acid (RNA)

Proteins are macromolecules that are composed of subunits called amino acids When the number of amino acids linked together becomes very large, or when multiple polypeptides are used as building subunits,
