Offside in open play Offside is quite a complicated rule of rugby union, so make sure you pay attention and listen to what the referee is saying. If a player is in front of a team-mate in possession of the ball, or in front of their team-mate who last played the ball, they will be offside if: 1  They are actively trying to play the ball. 2  Do not retire within 10m of an opponent who is waiting for the ball.
FRAMESHIFT MUTATION. This type of mutation occurs when the addition or loss of DNA bases changes a geneÂ´s reading frame. Extra base pairs may be added (insertions) or removed (deletions) from the DNA of a gene. The number can range from one to thousands. Collectively, these mutations are called indels.
Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions. Point mutations are the most common type of gene mutation.Also called a base-pair substitution, this type of mutation changes a single nucleotide base pair. Nonsense Mutation: This type of mutation alters the nucleotide sequence so that a stop codon is coded for in place of an amino acid. 2  A stop codon signals the end of the translation process and stops protein production.
