The length of the hockey stick is generally the easiest to determine, but imperative for a playerâs success in the game. Sticks usually come in four sizes: senior, intermediate, junior and youth. Each size normally reflects a smaller shaft circumference and a softer flex.
Factors in the environment may influence the rate of mutation but are not generally thought to influence the direction of mutation. For example, exposure to harmful chemicals may increase the mutation rate, but will not cause more mutations that make the organism resistant to those chemicals.In this respect, mutations are random  whether a particular mutation happens or not is unrelated to how useful that mutation would be.actors in the environment may influence the rate of mutation but are not generally thought to influence the direction of mutation.

During protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. 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.utations can also occur in which nucleotide base pairs are inserted into or deleted from the original gene sequence. This type of gene mutation is dangerous because it alters the template from which amino acids are read.
