A DNA building block of nucleic acid formed from a simple sugar, a phosphate group, and a nitrogenous base.
A change in the nucleotide-base sequence of a gene or DNA molecule
Ribonucleic Acid (RNA)
A nucleic acid consisting of a chain of nucleotides that contain the sugar ribose and the nitrogenous bases adenine, guanine, cytosine, and uracil. RNA performs protein synthesis.
To duplicate. The DNA molecule makes a copy of itself.
Double spiral; it describes the three-dimensional shape of DNA.
Nitrogenous base that pairs with thymine (T) during DNA replication.
Nitrogenous base that pairs with adenine (A) during DNA replication.
Nitrogenous base that pairs with guanine (G) during DNA replication.
Nitrogenous base that pairs with cytosine (C) during DNA replication.
States that base pairs occur in equal amounts. The amount of (A) = the amount of (T), and the amount of (C) = the amount of (G).
Refers to the copied DNA strand, or he matching base of another base. (ex. for sequence ATGCT the complimentary strand is TACGA)
Change to a chromosome in which a fragment of the chromosome is removed
A mutation in which a nucleotide or a codon in DNA is replaced with a different nucleotide
A mutation involving the addition of one or more nucleotide pairs to a gene.
A chemical or physical agent that interacts with DNA and causes a mutation, or change.
A technology in which the genome of a living cell is modified for medical or industrial use.
