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.
So in RNA the important base pairs are: adenine (A) pairs with uracil (U); guanine (G) pairs with cytosine (C). Transcription Transcription is the name given to the process where the information in a gene in a DNA strand is transferred to an RNA molecule.The coding strand and the template strand of DNA The important thing to realise is that the genetic information is carried on only one of the two strands of the DNA.he structure of RNA The function of messenger RNA in the cell You will probably know that the sequence of bases in DNA carries the genetic code. Scattered along the DNA molecule are particularly important sequences of bases known as genes. Each gene is a coded description for making a particular protein.
