Biology
1 answer:
mylen [45]4 years ago
4 0

Answer:

The correct answer is Each nucleotide is connected to three nitrogenous bases.

  • Deoxyribonucleic acid (DNA) is a genetic material composed of nucleotides.
  • Each nucleotide is made up of three elements: a phosphate group, a sugar group (deoxy ribose), and a nitrogenous base.
  • There are four types of nitrogenous bases found in the DNA : adenine (A), guanine (G), thymine (T), and cytosine (C).
  • Phosphate binds to a sugar group with the help of ester bond and sugar binds to a nitrogenous base with the help of glycosidic bond.
  • Nucleotides bind with each other with the help of phospodiester bond to form the polynucleotide chain.
  • The two nucleotide chains are held together with the help of hydrogen bonding between nitrogenous bases of two strands. They form the double helical structure of the DNA.
  • The two strands lei in anti-parallel orientation.
  • It is also important to note that adenine always binds with thymine with the help of two hydrogen bonds and guanine always binds with cytosine with the help of three hydrogen bonds.

stiv31 [10]

Answer:

film sensitive to radiation that is removed and developed to measure exposure.

a device used for monitoring individual cumulative exposure to ionizing radiation.

Explanation:

Film badges are monitoring devices that contain photographic film which measures and record the wearer’s exposure to different ionizing radiation such as X-rays, gamma rays and beta particles. The photographic film within film badges is very sensitive, functions as a detector, and is enclosed in a vapor and light resistance cover which disallows chemical vapors, light or moisture to have an effect on the film. Film badges give a lasting radiation record and it can also differentiate between different energies of photons.
