DNA
The shape of DNA
What is a double helix?
A change in the correct order of bases on a gene.
What is a mutation?
The process of selecting organisms with desired traits to be parents of the next generation
What is selective breeding?
A characteristic that an organism passes to offspring through its genes.
What is a trait?
A trait that increases an organism's ability to survive and reproduce
What is an adaptation?
What DNA stands for
What is deoxyribonucleic acid?
The process that must take place before a cell can divide
What is DNA replication?
When genes from one animal are transferred into the DNA of another organism
What is genetic engineering?
The process by which individuals that are better adapted to their environment are more likely to survive and reproduce more than other members of the same species
What is natural selection?
A group of similar organisms that can mate with each and produce fertile offspring
What is a species?
Four bases of DNA and how they are paired
What is adenine, thymine, guanine, and cytosine?
AT CG
Types of mutations
What is when a base is added, substituted, or deleted?
Crossing two individuals that have similar desirable characteristics, but could lead to genetic disorders
What is inbreeding?
Any difference in individuals of the same species
What is a variation?
Characteristics that help and organism survive and reproduce
What is a favorable trait?
DNA using the example of a book
What is:
Book = all of your DNA
Sentences = Genes
Words = Amino Acids
Letters = a Base (A, T, G, or C)
The importance of the order of base pairs
What is to prevent incorrect proteins or mutations from being made?
A cross of two genetically different individuals which are bred to have the best traits from both parents
What is hybridization?
A well stated concept that explains a wide range of observations
What is a theory?
Over time, organisms with favorable characteristics survive, and organisms without those characteristics die
What is population change?
Describe Translation and Transcription
What is: Translation = When amino acids use RNA to make proteins.
Transcription = When DNA is transcribed into RNA
The process the occurs with the DNA just before the cell divides
What is DNA replication?
Describe one example of genetic engineering
What is:
Diabetics taking insulin made from bacteria?
OR
Pest-resistant crops?
The five principles of natural selection
What is variation, favorable traits, survival or death of offspring, those that survive have the favorable trait, and population change?
Organisms produce more offspring than can survive
What is overproduction?
