So far, the text that has accompanied this picture has claimed the rattlesnake was killed in either Poteau Mountain, Arkansas or Olla, Louisiana. Although the location may change, the size of the snake is apparently being consistently reported as 11 feet 4 inches and 59 pounds (with 28 rattles). Let's start with what we know. The color and patterning of the snake give it away as a Timber Rattlesnake, Crotalus horridus.
DNA gyrase, often referred to simply as gyrase, is an enzyme that relieves strain while double-stranded DNA is being unwound by helicase. This causes negative supercoiling of the DNA.Bacterial DNA gyrase is the target of many antibiotics, including nalidixic acid, novobiocin, and ciprofloxacin. bacterial DNA topoisomerase II that catalyzes ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands. Gyrase binds to DNA as a heterotetramer consisting two A and two B subunits.
DNA Replication. Â­DNA carries the information for making all of the cell's proteins. These proÂ­teins implement all of the functions of a living organism and determine the organism'Â­s characteristics. When the cell reproduces, it has to pass all of this information on to the daughter cells.owever, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule. Let's look at the details: 1  An enzyme called DNA gyrase makes a nick in the double helix and each side separates. 2  An enzyme called helicase unwinds the double-stranded DNA.
