DNA
What results in a new DNA molecule that has one new strand and one new strand.
What is replication
The process of DNA to RNA
What is transcription?
An organism with two different alleles for a trait.
What is heterozygous?
The process by which populations become better adapted to their environment over time.
What is natural selection?
Separation of DNA by size
What is gel electrophoresis?
These enzymes cut double stranded DNA at precise sequences.
What are restriction enzymes?
A three nucleotide sequence on the tRNA that corresponds to a three nucleotide sequence on the mRNA.
What is an anticodon?
Inheritance that exhibits both of the homozygous traits.
What is codominance?
The original source of new genetic variation in a population.
What is mutation?
The types of structures that share a common ancestor but have a different function
What are homologous structures?
What are the three parts of a nucleotide?
What is phosphate, sugar, nitrogen base?
A change in one nucleotide in a codon
What is a point mutation?
A red and white plant have pink offspring
What is incomplete dominance?
Structures that have lost most or all of their original function.
What are vestigial structures?
Alternate forms of a gene
What is an allele?
What type of bond holds nitrogen bases together.
What are hydrogen bonds?
A nucleotide is inserted near the beginning of a gene. Every amino acid after the mutation changes.
What is a frameshift mutation?
If a father is blood type AB and a mother is blood type O, these blood types are possible in their children.
What are Type A and Type B?
This type of speciation occurs when populations are separated by a physical barrier.
What is geographic isolation?
This organelle contains digestive enzymes that break down waste and old cell parts.
What is a lysosome?
The percentage of guanine in a DNA sample if thymine makes up 30% of the bases.
What is 20%?
A student observes that mRNA is produced normally, but no protein is made. The cellular structure most likely malfunctioning is this
What is the ribosome?
If two heterozygous parents had a child, what is the chance the child would show the dominant trait?
What is a 75%?
The taxonomic level that contains the greatest number of organisms.
What is Kingdom?
If ribosomes stop functioning, the cell will no longer be able to do this effectively.
What is making protein?
