What is Protein Synthesis? (with pictures) - wiseGEEK
Inversions- DNA segment is excised and reinserted in opposite orientation.
*Codon-a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA.
Deletions are mutations in which a section of DNA is lost, or deleted.
In an inversion mutation, an entire section of DNA is reversed.

Typically affect a larger amount of genetic information than gene mutations.
Mutations make an important contribution to variation of traits.(evolution)
Mutations may be harmful, beneficial, or neutral...
-Proteins that are made from the genetic code are non or less funtional.
-Proteins that are made have more function or a new function that's beneficial.
A mutation isn't beneficial or harmful.
-refers to a procedure that is performed under sterile conditions.
As it is often used, the term protein synthesis typically excludes transcription and describes only the subsequent step of translation (see below).

These relationships are often called the rules of Watson-Crick base pairing, named after the two scientists who discovered their structural basis.
Code for various traits or features in an organism by coding for proteins that have specific functions.

RNA-ribonucleic acid, a nucleic acid present in all living cells.
Protein synthesis consists of a number of stages including: preparing molecules for use by the ; attaching the ribosome molecule to the ; and the initiation, elongation and termination phases of translation.

Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
The rules of base pairing (or nucleotide pairing) are:
A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T)
C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
The purine adnenine (A) will pair with the pyrimidine uracil (U) instead of thymine (T)
Base pairing is achieved by hydrogen bonds, a type of noncovalent reaction.
Why not A with C and G with T?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.
