DNA Structure, Function & Synthesis Vocabulary Crossword Puzzle

QUESTIONS LIST:

• codon : set of three nitrogen bases that represents an amino acid; order of nitrogenous bases in mrna determines the type and order of amino acids in a protein.
• karyo type : chart of metaphase chromosomes pairs arranged according to length and location of the centromere; used to pinpoint unusual chromosome numbers in cells.
• nucleic acid : complex biomolecules such as rna and dna, that store cellular information in cells in the form of code.
• dna replication : process in which chromosomal dna is copied before mitosis or meiosis.
• deoxyribonucleic acid : a nucleic acid; the master copy of an organism’s information code that contains the instructions used to used to form all od an organism’s enzymes and structural proteins.
• nucleotide : subunits of nucleic acid formed from a simple sugar, a phosphate group, and a nitrogen base.
• protein : large, complex polymer essential to all life composed of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur; provides structure for tissues and organs and helps carry out cell metabolism.
• translation : process of converting information in mrna into a sequence of amino acids in a protein.
• non disjunction : failure of homologous chromosomes to separate properly during meiosis; results in gametes with too many or too few chromosomes.
• nitrogenous base : carbon ring structure found in dna or rna that contains one or more atoms of nitrogen; includes adenine, guanine, cytosine, thymine, and uracil.
• transcription : process in the cell nucleus where enzymes make an rna copy of a dna strand.
• mutation : any change or random error in a dna sequence.
• amino acid : basic building blocks of protein molecules.
