HintAnswer
Three nucleotide sequence on tRNA that is the complementary sequence to one of the 64 codons of the genetic code
Type of RNA which, with ribosomal proteins, make up ribosomes (organelles that translate mRNA)
New DNA strand that is assembled in segments
Long chains of amino acid subunits
Type of RNA which brings amino acids to ribosomes during translation.
Thymine and adenine have this many hydrogen bonds.

New strand that is made in a continuous fashion
Replication begins at specific sites called ________.
Organelle that uses mRNA to direct the synthesis of a polypeptide
Genetic alteration of a cell by incorporation of naked DNA
Pyrimidine base in RNA that replaces Thymine
Path of information. Central dogma
Rules that govern genetic translation
Experiment that concluded that DNA is the hereditary material
Region of bases (TATA) that signals the beginning of a gene.
Incorporation of extrachromosomal DNA into the chromosome.
RNA copy of a gene used in the cell to produce a polypeptide
Mutations that generally involve one base pair
UAA, UAG, UGA
HintAnswer
Stage of gene expression where mRNA is used to direct the production of polypeptides

Fragments used to replicate the lagging strand
Mutation which causes change in the reading frame.
Three nucleotides unit on mRNA read by the ribosome that codes for a specific amino acid
Direction of transcription
