Mutations

Mutations. Mutate. A change in a cell which changes a trait. Usually a change in a gene sequence: …AACTAGGG A CATTTACG… …AACTAGGG C AATTTACG… Can also be a gene loss. Mutations. Causes: Radiation e.g. UV Chemical e.g. Cigarette Smoke Spontaneous Types:

MUTATIONS

MUTATIONS. WHAT HAPPENS IF DNA HAS ERRORS?!!!. What is the relationship between an organism’s DNA and protein specificity?. DNA becomes a specific part of the protein structure DNA determines the ribosomal RNA sequence that becomes part of the protein structure

MUTATIONS!

MUTATIONS!. Part One. MUTATIONS: WHAT ARE THEY ?. MUTATIONS:. are changes in the genetic material of the cell. can occur at the level of an individual DNA strand ( a point mutation ) or to an entire chromosome ( a chromosomal mutation ). MUTATIONS:.

MUTATIONS. Fitness of Mutations. The fitness of a mutation describes its value to the survival and reproductive success of the organism. A mutation may turn out to be: Lethal : Many mutations are lethal and embryos are non-viable .

Mutations. Monday November 5 th. What you need to know. A change in the DNA, or the genetic code of a cell, is called a mutation. Mutations can be classified as beneficial, neutral (cause no effect), or harmful . Harmful mutations may cause cancer

Mutations

Mutations. The fat cat ate the wee rat ???. Point Mutation. = a simple change in one base of the gene sequence. This is equivalent to changing one letter in a sentence, EXAMPLE: where we change the 'c' in cat to an 'h': Original - The fat cat ate the wee rat.
