DNA Replication
This enzyme unwinds the DNA double helix ahead of the replication fork.
Helicase
These short fragments are synthesized on the lagging strand.
RNA Polymerase
The start codon for translation in most organisms.
AUG (Methionine)
This Austrian monk is considered the father of genetics.
Gregor Mendel
The type of cell division that produces gametes.
Meiosis
This short stretch of RNA is laid down to provide a starting point for DNA synthesis.
RNA Primer
These noncoding sequences are removed from pre-mRNA before translation.
Introns
This type of RNA carries the genetic code from DNA to the ribosome.
mRNA
The physical appearance of an organism.
Phenotype
The phase before mitosis when DNA is replicated.
Interphase (S phase)
This enzyme adds nucleotides to the growing DNA strand in the 5’ to 3’ direction.
DNA polymerase
The mRNA is called this before it undergoes processing in eukaryotes.
pre-mRNA
The three-nucleotide sequence on mRNA that specifies an amino acid.
Codon
The genetic makeup of an organism.
Genotype
The stage where chromosomes line up along the cell’s equator.
Metaphase
This enzyme seals the gaps between fragments of DNA by forming phosphodiester bonds.
DNA ligase
Transcription begins when the RNA attaches to a section of DNA called this.
Promoter
his RNA molecule delivers specific amino acids to the ribosome.
tRNA
When two alleles for a trait are identical.
Homozygous
The process in Prophase I where homologous chromosomes exchange segments.
Crossing Over
These short fragments are synthesized on the lagging strand.
Okazaki Fragments
An RNA polymerase joins nucleotides together in this direction
5' to 3' direction
There are this many possible combinations of codons.
64
A genetic cross tracking only one trait
Monohybrid Cross
The stage where sister chromatids are pulled apart.
Anaphase
