bio 1
A discontinuously synthesized DNA strand that elongates by means of Okazaki fragments, each synthesized in a 5' to 3' direction away from the replication fork.
lagging strand
A mutation that changes a single nucleotide, but does not change the amino acid created.
Silent mutation
Developed the double helix model of DNA.
Watson and Crick
Small fragments of DNA produced on the lagging strand during DNA replication, joined later by DNA ligase to form a complete strand.
Okazaki fragments
A mutation that changes an amino acid codon to one of the three stop codons, resulting in a shorter and usually nonfunctional protein.
Nonsense mutation
transfer RNA; type of RNA that carries amino acids to the ribosome
tRNA
A region of DNA with a specific sequence that tells RNA polymerase where to begin transcription.
promoter
A base-pair substitution that results in a codon that codes for a different amino acid.
missense mutation
ribosomal RNA; type of RNA that makes up part of the ribosome
rRNA
insertion of foreign DNA into host cells, in order to have the host produce new proteins and traits
transformations
site of protein synthesis
Ribosome
messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome
mRNA
the new complementary DNA strand synthesized continuously along the template strand toward the replication fork in the mandatory 5' to 3' direction
leading strand
An organic compound that is made of one or more chains of amino acids and that is a principal component of all cells
Protein
AUG (methionine)
start codon
