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.
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.During DNA replication, DNA helicases unwind DNA at positions called origins where synthesis will be initiated.DNA helicase continues to unwind the DNA forming a structure called the replication fork, which is named for the forked appearance of the two strands of DNA as they are unzipped apart.here are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. During DNA replication, DNA helicases unwind DNA at positions called origins where synthesis will be initiated.
