DNA and Genes
It is what DNA stands for.
What is Deoxyribonucleic Acid?
This is defined as a structural change in a gene on a chromosome
What is a mutation?
Asexual reproduction results in offspring with this type of genetic information relative to the parent.
What is identical?
Sexual reproduction results in offspring with this, unlike asexual reproduction.
What is genetic variation?
This is the primary advantage of having genetic variation within a population.
What is the ability to adapt to changing environments?
This genetic material is common to all living organisms.
What is DNA?
These are the three possible effects a mutation can have on an organism.
What are harmful, beneficial, or neutral?
This is the number of parents involved in asexual reproduction.
What is one?
Sexual reproduction combines chromosomes from this many parents.
What is two?
A mutation is considered this if it provides a survival advantage.
What is beneficial?
(or an adaptation)
This specific section of DNA codes for a specific protein.
What is a gene?
Mutations alter proteins by changing the sequence of these "building blocks."
What are amino acids?
This is a common result of asexual reproduction, often seen in bacteria or plants.
What is a clone?
This process during sexual reproduction ensures that offspring have a unique mix of genes.
What is recombination?
A mutation that impairs an organism's function or survival is labeled as this.
What is harmful?
These structures carry genetic information in the form of genes.
What are chromosomes?
This specific type of mutation results in a change to a protein's function.
What is a _______ mutation?
(substitution, insertion, deletion)
Unlike sexual reproduction, asexual reproduction does not involve this process of "mixing" genes.
What is crossing over?
This specific event, involving the swapping of gene segments, occurs only in sexual reproduction.
What is crossing over?
This is often the first way scientists detect that a mutation has occurred in an organism.
What is observing changes in physical traits?
These molecules determine the structure and function of an organism's cells.
What are proteins?
These mutations are significant because they do not affect an organism's structure or function.
What are neutral mutations?
This is a major disadvantage of asexual reproduction in a changing environment.
What is a lack of genetic variation?
Sexual reproduction is vital to this long-term biological process by increasing variation.
What is evolution?
This is the role genetic information plays during the reproduction of all species.
What is determining the traits of the offspring?
