Paper Wallets. The codes for your currency can be printed out, and these hard copies can be stored in a regular wallet, just like traditional bill-and-coin currency. These are ideal for traders who intend to invest most of their cryptocurrency, and not use it as much for purchases.
Alternate forms of a gene are called alleles. Alleles are one of  two or more alternative forms of a gene that arise by mutation and  are found at the same place on a chromoâ¦some.
Nonsense mutations. With a nonsense mutation, the new nucleotide changes a codon that specified an amino acid to one of the STOP codons (TAA, TAG, or TGA). Therefore, translation of the messenger RNA transcribed from this mutant gene will stop prematurely.ingle base substitutions are also called point mutations. (If one purine [A or G] or pyrimidine [C or T] is replaced by the other, the substitution is called a transition. If a purine is replaced by a pyrimidine or vice-versa, the substitution is called a transversion .).
