A virus that infects bacteria
These are DNA's 4 nitrogenous bases.
What are adenine, thymine, guanine, cytosine?
A copying process which duplicates the DNA.
The shape of a bacteria cell's DNA.
These compounds consist of 3 parts: a 5 carbon sugar, a phosphate group, and a nitrogenous base.
DNA at the tips of chromosomes which is difficult to replicate.
The material incorporated into the bacterial DNA by a phage.
This is the overall shape of DNA, where 2 DNA molecules twist around each other like a ladder.
The complementary DNA strand if the original strand's sequence is CGTA.
The process where 1 strain of bacteria is changed by genes from another strain of bacteria.
This scientist studied the r-strain and s-strain of bacteria and how it influenced mice.
These bonds are easily broken and for between certain nitrogenous bases.
To store, copy, and transmit genetic information in a cell.
These scientists used radioactive materials on bacteriophages to see which material got passed on to bacteria cells, DNA or proteins. They found that DNA was the molecule responsible.
These are the type of bonds that form between the sugar group of one nucleotide and the phosphate group of the next nucleotide.
These are bead-like structures of DNA and histones.
