DNA Vocabulary

Across
system of nucleotide triplets in DNA and RNA that carries genetic information
biopolymers are antiparallel if they run parallel to each other but with opposite alignments. An example is the two complementary strands of a DNA double helix, which run in opposite directions alongside each other
threadlike, gene-carrying structure found in the nucleus
double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins
Body
Process of making a copy of DNA
Any cell in a multicellular organism except a sperm or egg cell
Enzyme

specific pairing of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA
The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape
polymer consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA.
organic base that contains the element nitrogen, includes adenine, guanine, cytosine, thymine and uracil (RNA)
essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied
