Seafloor spreading and subduction are the driving forces of continental drift.   Pangaea was the Earth's only continent 4 bi â¦ llion years ago. Tectonic plates are small plates, while continent drift is several tectonic plates moving as a mass (continent).
The genetic code is the code that translates a sequence of three nucleotides (called a codon) into an aminoacid. The genetic code has those two properties: Unambiguous: Each codon is translated into one single aminoacid. Always.This means that UUA is the code leucine no matter what.Redundant: In some cases, there are more than one codons for a single aminoacid.For instance UUA means leucine, but so does UUG.est Answer: In a molecule of DNA, many sequences are repeated and therefore essential not used. These repeated sequences are known as redundant DNA. Ambiguous DNA is sections where the code is not precisely known but its known that it is one of two bases. These are represented by characters e.g.
3. The genetic code is commaless, which means that no codon is reserved for punctuations. It means that after one amino acid is coded, the second amino acid will be automatically, coded by the next three letters and that no letters are wasted as the punctuation marks (Fig.
