What is the DNA twisted structure called?
AnswerThe "twisted ladder" shape of DNA is called a double helix.
What is the Structure of histones and non histones?
Histones are the major protein structure of chromosomes. The DNA is wrapped twice around a histone octamer to create a nucleosome, which are assembled six at a time to make a Solenoid. Solenoids coil into a scaffold, which is then coiled itself to make the chromosomal matrix.
What Stores and transmits genetic information called?
In a cell, DNA or Deoxiribose Nucleic Acid stores and transmits genetic information.
The genetic code of a DNA molecule is determined by a specific sequence of WHAT?
A gene is a sequence of nucleotide which is composed of a nitrogenous base(adenine,guanine,thymine & cytosine in case of DNA and thymine is replaced by uracil in case of RNA),a sugar residue(de-oxyribose in DNA & ribose sugar in RNA) and a phosphate group.
What cell structure is made up of the genetic material?
Chromosomes are long, wound up strands of the genetic material, DNA.
How do supercoils affect the structure and function of DNA?
Supercoils are twists and turns in the DNA molecule that can impact its structure and function. These supercoils can affect how DNA is packaged and organized within the cell, which in turn can influence processes like gene expression and replication. In some cases, supercoiling can help regulate gene activity by making certain regions of DNA more accessible or less accessible to proteins that control gene expression. Overall, supercoils play a role in shaping the three-dimensional structure of DNA and can impact its ability to carry out essential functions within the cell.
Why is reverse gyrase called reverse gyrase?
The enzyme DNA gyrase produces negative supercoils in DNA. The "negative" refers to the directionality of the supercoil, not the electrical charge of the molecule. Reverse gyrase produces positive supercoils, meaning the DNA supercoils in the opposite direction of the negative supercoil.
How does topoisomerase affect the DNA strand during DNA replication?
The topoisomerase enzyme uncoils the double helical structure of DNA during its replication to form the replication fork. In eukaryotes both posive and negative supercoils get unbind by topoisomerase I & II respectively.Topoisomerase isomerase unwinds DNA to form replication fork
What contribution did Francis Crick make to the discover of the structure of DNA?
they described the structure of DNA
Why is DNA known as double helix structure?
Tis' just another word for DNA.
Can you give a hard science question?

The Watson and Crick model of DNA is known as a?
Double helical structure
What structure houses a eukaryotic cell's DNA?
The structure that house a eukaryotic cells DNA is known as the nucleus. The nucleus has a membrane that is similar to a cell membrane.
Who was the current DNA structure model proposed by?
James Watson and Francis Crick proposed the current DNA structure model in 1953, which is known as the double helix.
How proteins help the support the structure and function of DNA?
DNA is packaged very tight by proteins. Proteins found around the DNA supports both the structure and functions. The proteins and the DNA make up the chromosomes. Proteins and DNA in animal cells are chromatin! DNA contains information because of the DNA's structure!
What kind of sugar is used to make DNA?
Deoxyribose is the monosaccaride that serves as the 'backbone' for the DNA structure.
What is the function of DNA gyrase?
DNA gyrase is a bacterial enzyme which introduces supercoils into the bacterial DNA, resulting in a highly condensed 3-dimentional struture. it is also known as Topoisomerase. Quinolones and F/Quinolones inhibit this enzyme and thus interfere with bacterial DNA replication. The enzyme is absent in humans.
