Start codon
His experiment conducted in 1928 described the process of transformation
Mutations that generally involve one base pair
Genetic alteration of a cell by incorporation of naked DNA
Copying process that makes mRNA
Type of RNA which, with ribosomal proteins, make up ribosomes (organelles that translate mRNA)
Experiment that concluded that DNA is the hereditary material
Composed of a sugar, a phosphate group, and an organic base
Stage of gene expression where mRNA is used to direct the production of polypeptides
Phage-mediated gene transfer
Direction of transcription
Mutation which causes change in the reading frame.
New strand that is made in a continuous fashion
Type of RNA which brings amino acids to ribosomes during translation.
Three nucleotides unit on mRNA read by the ribosome that codes for a specific amino acid
Three nucleotide sequence on tRNA that is the complementary sequence to one of the 64 codons of the genetic code
Gene transfer through the sex pilus
HintAnswer
Region of bases (TATA) that signals the beginning of a gene.
Used X-rays to produce evidence of the helical nature of DNA.
Incorporation of extrachromosomal DNA into the chromosome.
Cystosine and guanine have this many hydrogen bonds.
Any change in the nucleotide sequence of DNA
Rules that govern genetic translation
