What Does DNA Do? DNA is like a set of instructions that govern the arrangement of amino acids. It is composed of various 3 letter codes, calledcodons. These codons need to be interpreted in order to attain the correct amino acid. Think of it as a password that, if entered correctly, ...
In what two ways do bacteria grow or multiply. Explain these processes. What aspects of bacteria make them a useful tool to molecular biologists, who have used bacteria in cloning DNA of interest for decades? Answer in terms of overall safety, bacterial growth rate, bacterial DNA makeup, and...

internal structures and external appendages. Unlike mammals and other eukaryotes, bacteria do not possess a nucleus; instead, the chromosomal DNA is found in a dense region of cytoplasm known as the nucleoid. Extra ring-shaped DNA is also found in some bacteria and these are known as plasmids ...
What is DNA primase? What starts DNA replication? What is DNA transcription? What does DNA do in a plant cell? Can double-stranded RNA viruses replicate with just their genome? What genes are involved in DNA repair? What does viral nucleic acid do in the lytic cycle?
What bacteria does rifampin kill? Rifampin and its analogues kill actively multiplying extracellular organisms,intracellular mycobacteria, and semidormant mycobacteriain tissues. What is the action of rifampin? Mechanism of action — Rifampin is thoughtto inhibit bacterial DNA-dependent RNA polymerase, which...
What doesbacteriamean? Our full, formal definition ofbacteria: Bacteriaareubiquitousone-celled organisms, spherical, spiral, or rod-shaped and appearing singly or in chains, comprising the Schizomycota, a phylum of the kingdom Monera (in some classification systems the plant class Schizomycetes),...
Bacterial cells are generally surrounded by an outer cell wall and an inner cell membrane. Certain bacteria, like the mycoplasmas, do not have a cell wall at all. Some bacteria may even have a third, outermost protective layer, called the capsule. Whip-like extensions often cover the surfaces...
What are two organelles that contain DNA?Organelles:Organelles are tiny structures within cells that perform specialized functions. Some examples of organelles include lysosomes and peroxisomes. Some organelles contain DNA and are the food producers of the plants they reside in....
