the transfer of genetic material in the form of DNA fragments from one cell to another or from one organism to another
in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base
an organic base that contains nitrogen, such as a purine or pyrimidine; a subunit of a nucleotide in DNA and RNA
a nitrogenous base that has a double-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; either adenine or guanine
a nitrogenous base that has a single-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; thymine, cytosine
the rules stating that in DNA cytosine pairs with guanine and adenine pairs with thymine and that in RNA cytosine pairs with guanine and adenine pairs with uracil
Complementary Base Pair
the nucleotide bases in one strand of DNA or RNA that are paired with those of another strand; adenine pairs with thymine or uracil, and guanine pairs with cytosine
Hershey and Chase
who found that all of the viral DNA and little of the protein had entered E coli cells
realized through experiments with rats that heated bacteria can transfer genetic information to other bacteria
a Y-shaped point that results when the two strands of a DNA double helix separate so that the DNA molecule can be replicated
RNA contains ribose not deoxyribose
uracil not thymine
RNA is single strand DNA-double
RNA is shorter than DNA
List the four ways in which the structure of RNA differs from DNA
The type of RNA that binds to specific amino acids and transports them to the ribosome during protein synthesis
1. RNA polymerase binds to the promoter of a specific gene
2.DNA strands separate
3. RNA polymerase adds complementary RNA nucleotides to newly formed RNA
4. RNA reaches termination detaches
Main steps of transcription
(genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm
the formation of proteins by using information contained in DNA and carried by mRNA
group of three bases on a tRNA molecule that are complementary to the three bases of a codon of mRNA
the complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes
method of replication that implies that each new strand of DNA is half original and half new
DNA polymerase form new strands by adding_____ nucleotides to each of the original strands
