# data[].attributes.body
Definition - enzymes that correct errors in nucleotide sequencing

IN A SENTENCE: Animal cells have DNA polymerases that are responsible for the replication of DNA in the nucleus and mitochondria.

# data[].attributes.body
Definition - molecules that bring amino acids to the ribosomes during translation

IN A SENTENCE: The hypothesis was explored that viral tRNA genes originate from their host.

# data[].attributes.body
Definition - nucleotide sequences of tRNA that are complementary to codons on mRNA

IN A SENTENCE: Anticodon breakage inhibits protein synthesis, which, in turn, results in growth arrest or cell death.

# data[].attributes.body
Definition - two strands of code that pair up by nitrogen bases

IN A SENTENCE: Complementary DNA is not genomic DNA, because the transcript of genomic RNA has been processed (i.e., it lacks promoters and introns).

# data[].attributes.body
Definition - viruses that infect bacteria

IN A SENTENCE: The study compared the genomes of 627 bacteriophages isolated from a single species of bacteria, and found a continuum of genetic diversity, rather than discrete groups within the population.

# data[].attributes.body
Definition - the nitrogen base that is ONLY found in RNA

IN A SENTENCE: Uracil may be recycled by a salvage pathway.

# data[].attributes.body
Definition - the shape of DNA discovered by Watson and Crick

IN A SENTENCE: Genetics and crime fighting are becoming as intertwined as the DNA double helix.

# data[].attributes.body
Definition - enzymes that unwind the DNA double helix by breaking the hydrogen bonds

IN A SENTENCE: The helicase must act specifically and rapidly to prevent replication fork collapse.

# data[].attributes.body
Definition - the process by which messenger RNA (mRNA) is produced

IN A SENTENCE: The gene could be mutated during transcription into the genetic code, and could perhaps make any genetic problem even worse.

# data[].attributes.body
Definition - the process by which DNA copies itself

IN A SENTENCE: Often, the genetic material is missing due to an error in the replication of an egg or sperm cell.
