Instructions
What does RNA carry from DNA?
100
The process by which DNA is copied during the cell cycle.
What is replication?
100
A piece of DNA that provides a set of instructions to a cell to make a certain protein.
What is a gene?
100
The exchange of chromosome segments between homologous chromosomes.
What is crossing over?
100
The creation of offspring from a single parent.
What is asexual reproduction?
200
The process of copying a sequence of DNA to produce a complementary strand of RNA.
What is transcription?
200
Proteins
Which macromolecule carries out the process of replication?
200
Any of the alternative forms of a gene that may occur at a specific locus.
What is an allele?
200
A change in an organism's DNA.
What is a mutation?
200
Binary Fission
What is an example of asexual reproducion of a single celled organism?
300
An enzyme that bonds nucleotides to make a new RNA molecule.
What is RNA polymerase?
300
This takes place in the nucleus in eukaryotic cells and involves DNA unwinding and nucleotide base pairing. It produces an RNA molecule.
What is transcription?
300
The alleles are identical to each other.
What is homozygous?
300
Agents in the environment that can change an organism's DNA.
What are mutagens?
300
Metaphase
What is the phase of mitosis where chromosomes align on the midline of the nucleus?
400
Flow of information from DNA to RNA to Proteins.
What is the Central Dogma?
400
Both transcription and replication take place within this same organelle.
What is the nucleus?
400
These alleles are different from each other.
What is heterozygous?
400
An insertion or deletion of a nucleotide in the DNA sequence.
What is frameshift mutation?
400
Identical Offspring
What is the result of asexual reproduction?
500
Francis Crick
Who discovered the DNA structure?
500
This process converts, or translates, an mRNA message into a polypeptide. One or more polypeptides make up a protein.
What is translation?
500
This allele is the allele that is expressed when two different alleles or two dominant alleles are present.
What is dominant?
500
The reason mutations in body cells are not passed on to offspring.
What is because body cells are not passed from one generation to another.
500
