Chapter 8 - DNA, RNA and Protein Synthesis

Teacher:
Across
Change in the DNA sequence
Enzyme that catalyzes the synthesis of a complementary strand of RNA from a DNA template
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 stop translation
Nucleic acid molecule that allows for the transmission of genetic information and protein synthesis
Virus that infects bacteria
Set of three nucleotides in a tRNA molecule that binds to a complementary mRNA codon during translation
Sequence of three nucleotides that codes for one amino acid
Down
Form of RNA that brings amino acids to ribosomes during protein synthesis
Form of RNA that carries gynetic information from that nucleus to the cytoplasm, where it serves as a template for protein synthesis
Process of copying a nucleotide sequence of DNA to form a complementary strand of mRNA
Rule that describes how nucleotides form bonds in DNA; Adanine (A) always bonds with Thymine (T), and Guanine (G) always bonds with Cytosine (C)
Theory that states that, in cells, information only flows from DNA to RNA to proteins
Enzyme that makes bonds between nucleotides, forming an identical strand of DNA during replication
Mutation that involves a substitution of only one nucleotide
Process by which mRNA is decoded and a protein is produced
Model that compares the structure of a DNA molecule, in which two strands wind around one another, to that of a twisted ladder
Codon that signals to ribosomes to begin translation; codes for the first amino acid in a protein
Monomer that forms DNA and has a phosphate group, a sugar, and a nitrogen-containing base
Process by which DNA is copied
