Mitosis and Meiosis
The cell spends the most time in this phase of the cell cycle.
What is interphase?
He is known as the Father of Genetics
Who is Gregor Mendel?
DNA and RNA are made up of what building blocks?
What are nucleotides?
This is used to make large amounts of insulin today
What are Genetically Modified Organisms/bacteria?
This is a characteristic that makes an organism more suited for its environment
What is an adaptation?
Results in two identical daughter cells and is important for normal cell growth
What is mitosis?
These are different versions of a gene and can be dominant or recessive.
What are alleles?
The cell needs to do this in the S phase before Mitosis or Meiosis?
What is replicate or copy DNA?
These crops can be made to be resistant to herbicides or insecticides
What are Genetically Modified Plants/Crops?
Darwin's mechanism for evolution that says individuals with favorable inherited traits are more likely to survive and reproduce
What is Natural Selection/Descent with Modification?
The number of chromosomes in each cell after meiosis.
What is half or haploid?
This is the scientific term for the physical appearance of a trait.
What is phenotype?
This enzyme adds DNA nucleotides to the leading and lagging strands.
What is DNA polymerase?
These are changes in the genetic material in the cell and can lead to variations.
What are mutations?
Anatomically similar structures that are explained by a common ancestor
What are homologous structures? forelimbs of vertebrates
Meiosis results in the creation of what types of cells?
What are gametes...egg or sperm cells?
What is the Law of Segregation?
What is transcription?
Caused by a non-disjunction event resulting in individuals with three copies of chromosome 21.
What is Down Syndrome?
What is allele frequency?
This event in meiosis is important for genetic variation and does not happen in mitosis.
What is crossing over during Prophase I?
Albinism and Sickle Cell disease are examples of what type of traits?
What is autosomal recessive?
This recognizes the codon and brings an amino acid to the ribosome during translation
What is tRNA?
This type of analysis shows pairs of homologous chromosomes arranged by size, shape and patterns.
What is a karyotype?
This effect leads to a drastic reduction in population size due to a sudden or random environmental change?
What is the bottleneck effect/genetic drift?
