Mutation: a change in the genetic material of a cell.Not all mutations are harmfulMutations in the gametes (germ cells) can be passed on to the offspringOther mutations affect somatic (body) cells . Mutation. Gene mutations occur in individual genes.Point mutations affect only one nucleotide.substitution2. Frameshift mutations affect all the codons after the point mutationinsertion deletion.

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

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 .

Central America . 7. A Rugged Land. Central America includes the countries of Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama. . Central America is an isthmus, or narrow piece of land that links two larger areas of land.  It links North and South America.

Mutations. Gene Mutations. Mutations that result in changes to a single gene. Point Mutation. One base pair in the DNA sequence is copied incorrectly. Sickle Cell Anemia. Normal vs. Sickle Cell. Normal DNA: {TAG}{CTT}{ATT} RNA: {AUC}{GAA}{UAA} Sickle Cell

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.

Mutations. Start a New Page Add it to your TOC. Thesunwashotbuttheoldmandidnotgethishat. This is (kind of) like a strand of DNA. Each letter represents a base (A,C,T,G). The sun was hot but the old man did not get his hat. It has meaning when we break it into groups of three.

Mutations

Mutations. Mutations. A section of DNA on a chromosome that directs the making of a specific protein is called a gene Genes control the traits inherited by an organism If a change occurs in a gene or chromosome, a trait of that organism may be changed

Mutations!. Types of Mutations . Point Mutations: one base is changed Substitutions Insertions Deletions Both Insertions and Deletions are also called frameshift mutations because the codons are not read correctly Mutations can happen in both DNA and in RNA. Mutations.

Mutations

Mutations. DNA Mistakes. DNA is a molecule that replicates, works and copies with very high accuracy DNA has enzymes that make sure that it works with a high level of accuracy and detail DNA can often work without mistake. DNA Mistakes. DNA can however make mistakes

Mutations

Mutations. What Are Mutations?. Changes in the nucleotide sequence of DNA May occur in somatic cells (aren’t passed to offspring) May occur in gametes (eggs & sperm) and be passed to offspring. Are Mutations Helpful or Harmful?. Mutations happen regularly
