DNA & Genes
This molecule stores genetic information.
What is DNA?
This molecule carries genetic instructions from DNA to the ribosome.
What is mRNA?
This term means an organism's genetic makeup.
What is genotype?
This process produces gametes.
What is meiosis?
This means the likelihood that an event will occur.
What is probability?
These structures are found in the nucleus and carry genetic information.
What are chromosomes?
The central dogma begins with this molecule.
What is DNA?
This term refers to an organism's observable traits.
What is phenotype?
This process produces identical cells.
What is mitosis?
This is increased by sexual reproduction.
What is genetic variation?
These are the specific sections of chromosomes that provide instructions for making proteins.
What are genes?
The central dogma ends with the production of this molecule.
What is a protein?
These are different versions of a gene.
What are alleles?
This process produces genetically unique cells.
What is meiosis?
These two cells join during fertilization.
What are sperm and egg?
This molecule is the building block of proteins.
What is an amino acid?
This determines the genetic code.
What is the base sequence?
This term describes having two identical alleles.
What is homozygous?
This is the number of chromosomes found in a human gamete.
What is 23?
This process occurs when a sperm cell joins an egg cell.
What is fertilization?
This is the organelle where DNA is found in a typical eukaryotic cell.
What is the nucleus?
Gene expression results in the production of this.
What is a protein?
This term describes having two different alleles.
What is heterozygous?
This is the fraction or percentage by which meiosis reduces the chromosome number.
What is one-half or 50%?
This is the percentage of offspring that have a dominate genotype.
