Mitosis
In Mitosis, this is the number of daughter cells produced from one parent cell.
What is 2?
In Meiosis, this is the number of daughter cells produced from one parent cell.
What is 4?
A different version of the same gene
What is an allele?
During transcription, DNA is transcribed into this single-stranded molecule
What is mRNA?
The naturalist that first proposed populations evolve by natural selection
Who is Charles Darwin?
Which type of eukaryotic cell contains two copies of each chromosome (homologous pairs)?
What is a diploid cell?
Daughter cells formed from meiosis have exactly 1/2 set of DNA, also known as what type of cell?
What is haploid?
In human blood types, type A and type B blood are both _________ to type o blood.
What is co-dominant?
The number of consecutive mRNA bases that make one codon
What is 3?
Possession of inherited adaptations that are well-suited to the environment is central this well-supported mechanism of evolution
What is natural selection?
During DNA replication, DNA makes genetically identical strands and attach them to each other at the centromere for division. The identical strands are known as this.
What are sister chromatids?
Meiosis is a process used for creating these types of cells.
What are gametes (sperm and egg cells)?
A person has a recessive allele for a disease but the allele is masked by the presence of a normal dominant allele in the person. This person is referred to as this in regards to this disease
What is a carrier?
Given the following DNA strand, this is the resulting mRNA strand: TACAAT
What is AUGUUA?
This is the basis of genetic diversity that leads to evolution by natural selection
What is genetic mutations?
Cells that have lost control of the cell cycle and continue to divide and replicate with faulty DNA are classified as this disease.
What is cancer?
In meiosis, DNA replication occurs when?
What is before meiosis 1?
Suppose a white-furred rabbit breeds with a black-furred rabbit and all of their offspring have a phenotype of gray fur. The gene for fur color in rabbits appears to be an example of this pattern of inheritance.
What is incomplete dominance?
This is how a different end protein product than what is coded for in the DNA occurs.
What is a mutation?
A human tail bone and appendix are examples of structures that were once used by an ancestral species, but has lost its use/need in the modern species. These structures are referred to as this type of structure.
What are vestigial structures?
Sister chromatids separate and move to opposite poles of the cell (pulled apart by spindle microtubules) during this phase of mitosis
What is anaphase?
During meiosis 1, segments of DNA may be exchanged between maternal and paternal homologues. This leads to new combinations of alleles and genetic diversity within a population. This process is referred to as..
What is crossing over?
If you cross two heterozygous (Yy) pea plants, what proportion of the offspring will be heterozygous?
50%
What type of mutation occurred in the DNA strand below?
Original strand: AGGCTCGAT
Mutated strand: AGGTTCGAT
What is a substitution (4th base changed from a Cytosine to a Thymine)?
If a finch population with heritable, variable beak size and shape arrived on an island on which only large seeds were available as a source of food, describe the natural selection process that would follow.
Finches with larger beaks will more easily eat the large seeds and thus more likely survive and produce offspring with similarly large beaks. The frequency of large beaks within the population will increase.
