Monomer that forms DNA and has a phosphate group, a sugar, and a nitrogen-containing base
Model that compares the structure of a DNA molecule, in which two strands wind around one another, to that of a twisted ladder
Base Paring Rules
Rule that describes how nucleotides form bonds in DNA; adenine (A) always bonds with thymine (T), and guanine (G) always bonds with cytosine (C)
Enzyme that makes bonds between nucleotides, forming an identical strand of DNA during replication
Nucleic acid molecule that allows for the transmission of genetic information and protein synthesis
Process of copying a nucleotide sequence of DNA to form a complementary strand of mRNA
Enzyme that catalyzes the synthesis of a complementary strand of RNA from a DNA template
Messenger RNA (mRNA)
Form of RNA that carries genetic information from the nucleus to the cytoplasm, where it serves as a template for protein synthesis
Ribosomal RNA (rRNA)
RNA that is in the ribosome and guides the translation of mRNA into a protein; also used as a molecular clock
Codon that signals to ribosomes to start being translation; codes for the first amino acid in a protein
Set of three nucleotides in a tRNA molecule that binds to a complementary mRNA codon during translation
Section of DNA that contains all of the code to being transcription, regulate transcription, and build a protein; includes a promoter, regulatory gene, and a structural gene
Mutation that involves the insertion or deletion of a nucleotide in the DNA sequence
