Genetics Quiz

chromosome = A discrete unit of the genome carrying many genes. allele = One of several alternative forms of a gene occupying a given locus on a chromosome. locus = The position on a chromosome at which the gene for a particular trait resides; it may be occupied by any one of the alleles for the gene. genetic recombination = A process by which separate DNA molecules are joined into a single molecule, due to such processes as crossing over or transposition.

structural gene = A gene that encodes any RNA or polypeptide product other than a regulator. transforming principle = DNA that is taken up by a bacterium and whose expression then changes the properties of the recipient cell. transfection = In eukaryotic cells, the acquisition of new genetic markers by incorporation of added DNA. nucleotide = A nucleoside linked to a phosphate group on either the 5′ or 3′ carbon of.

<p>supercoiling = The coiling of a closed duplex DNA in space so that it crosses over its own axis. complementary = Base pairs that match up in the pairing reactions in double helical nucleic acids. overwound = B-form DNA that has more than 10.4 base pairs per turn of the helix. underwound = B-form DNA that has fewer than 10.4 base pairs per turn of the helix.</p> Signup and view all the answers

<p>semiconservative replication = DNA replication accomplished by separation of the strands of a parental duplex, each strand then acting as a template for synthesis of a complementary strand. DNA polymerase = The enzyme responsible for DNA replication. denaturation = In DNA, this involves the separation of the two strands due to breaking of hydrogen bonds between bases.</p> Signup and view all the answers
