What are the three stop codons? Genetic Code: A codon is a nucleotide base triplet. There are four different bases; therefore, there are a total of 64 codons. The set of rules that determine the pairs corresponding amino acids and codons is known as the genetic code. Three codons are kno...
Which nitrogenous bases would be found on the MRNA transcribed from a DNA strand with the following nucleotide sequence: AAA/TTT/GGG/CCC and why? Which of the following codons can only come from a strand of RNA? a) ATG b) TGC c) Two of the answers are correct. d) GCG e) CAU...

mRNA and tRNA are synthesized through processes called "base pairing" and "transcription," wherein a chain of RNA is laid down, alongside a strand of deoxyribonucleic acid (DNA). In bacteria and archaea, two of the three major divisions of life on Earth, RNA synthesis takes place along a ...
Besides this, one codon code for the synthesis of only one specific amino acids, so, it cannot code for any other amino acid. However, there aresome amino acids that are coded by more than one codon. The codon is read in mRNA in a continuous fashion, no gap between two codons. Also...
Beyond such mundane trivia, however, lies an elegant and impressively well-studied structure that exists in almost every cell of every living thing. DNA is the stuff of genes on a smaller scale and chromosomes, which are collections of many, many genes, on a larger scale; together, all of...
Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation,insertions and deletionsare usually more harmful than a substitution in which only a single amino acid is altered....

Usually, the single amino acid is encoded by a single codon. However, some amino acids are encoded by more than one codon. e.g. Cysteine has two codons, while isoleucine hasthree codons. This is called the degeneracy of the code.
Translation is the process whereby the mRNA molecule produced during transcription is used to build the protein encoded in the mRNA at the ribosome. The mRNA molecule contains codons. Codons are segments of 3 bases that code for different amino acids. These codons are read and tRNAs bring ...
