There are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). This sequence is broken into a series of three-nucleotide units known as codons. Each DNA sequence that contains instructions to make a protein is known as a gene.
Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.
DNA sequencing was built upon earlier knowledge of DNA polymerases and cell-free systems for replicating DNA. The chain-termination method, which makes clever use of a "defective" DNA nucleotide, now dominates DNA sequencing technology.

Chemical energy is converted into chemical energy.
<em>Answer : </em>chemical-A.
Answer:
Tympanic membrane. (Ans. A)
Explanation:
Tympanic membrane: It is known as thin semitransparent eardrum, which is formed boundary between the external and middle ear. It's diameter is about 0.3-0.4 inch, and cone shaped membrane. Tympanic membrane is found in humans, and other tetrapods.
Its playing an important role in to transfer sounds which is present in the air to the ossicles inside the middle ear, then to the oval window of the fluid-filled cochlea.
