DNA Crossword Puzzle

QUESTIONS LIST:

• double helix: a pair of parallel helices intertwined aboucomt a mon axis,especially that in the structure of the dna molecule.
• anticodon: a sequence of three nucleotides in a region of transfer rna that recognizes a complementary coding triplet of nucleotides in messenger rna during translation by the ribosomes in protein biosynthesis.
• dna polymerase: any of a class of enzymes involved in the synthesis of deoxyribonucleic acid from its deoxyribonucleoside triphosphate precursors.
• rna polymerase: an enzyme that synthesizes the formation of rna from a dna template during transcription.
• central dogma: molecular biology describes the two-step process, transcription and translation,by which the information in genes flows into proteins.
• translation: the process follows transcription in which the dna sequence is copied (or transcribed) into an mrna.
• rna: any of a class of single-stranded molecules transcribed from dna in the cell nucleus or in the mitochondrion or chloroplast
• messenger: the form of rna in which genetic information transcribed from dna as a sequence of bases is transferred to a ribosome.
• mutation: occurs when a dna gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
• replication: the process by which double-stranded dna makes copies of itself, each strand, as it separates, synthesizing a complementary strand.
• transcription: the first step of gene expression, in which a particular segment of dna is copied into rna.
• nucleotide: a compound consisting of a nucleoside linked to a phosphate group. nucleotides form the basic structural unit of nucleic acids such as dna.
• ribosomal: a type of rna, distinguished by its length and abundance, functioning in protein synthesis as a component of ribosomes.
• codon: a triplet of adjacent nucleotides in the messenger rna chain that codes for a specific amino acid in the synthesis of a protein molecule.
