Gene Expression and Control Crossword Puzzle

QUESTIONS LIST:

• uracil : nucleotide abbreviated as u
• factors : transcription _ are proteins that influence transcription by binding to dna
• expression : gene _ is the process by which the information in a gene guides assembly of an rna or protein product. includes transcription and translation
• substitution : base-pair _ is a mutation in which a single base pair changes
• barr : inactivated x chromosome in a cell of a female mammal is called a _ body
• knockout : an experiment in which a gene is deliberately inactivated in a living organism
• promoter : dna sequence that is a site where rna polymerase binds for transcription
• master : genes encoding a product that affects the expression of many other genes
• messenger : rna that has a protein building message
• code : a genetic _ is a complete set of sixty-four mrna codons
• transcription : process by which enzymes assemble an rna using a strand of dna as a template
• intron : nucleotide sequence that intervenes between exons and is removed during post-translational modification
• deletion : mutation in which one or more nucleotides are lost
• differentiation : all cells of an embryo share the same genes; different cells in it become specialized as they begin to use different subsets of those genes, a process called

• anticodon : in a trna the set of three nucelotides that base-pairs with an mrna codon
• transfer : rnas that deliver amino acids to the intact ribosome
• epigenetic : refers to heritable changes in gene expression that are not the result of changes in dna sequence
• translation : process by which the protein-building instructions in an mrna guide the assembly of polypeptide
• exon : nucleotide sequence that remains in an rna after post-transcriptional modification
• codon : in an mrna, a nucleotide base triplet that codes for an amino acid or stop signal during translation
• gene : a part of a chromosome that encodes an rna or protein product in its dna sequence
