The quiz randomly chooses terms from the Talking Glossary and asks the user to select a term name to match the definition shown. Hints are available for each question, and at the end of the quiz all users are able to print a "Certificate of Completion" that includes the date the test was taken, number of correct answers, and the user's name.
DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. [14] The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and ...

Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.
Selected portions of the DNA nucleotide sequence are copied into a corresponding RNA nucleotide sequence, which either encodes a protein (if it is an mRNA) or forms a 'structural' RNA, such as a transfer RNA (tRNA) or ribosomal RNA (rRNA) molecule. Each region of the DNA helix that produces a functional RNA molecule constitutes a gene. [15]
The Impossible Quiz is a point-and-click quiz game that consists of 110 questions, [1] [2] using "Gonna Fly Now" as its main musical theme. Notorious for its difficulty, the quiz mixes multiple-choice trick questions similar to riddles, along with various challenges and puzzles. [1] [2] Despite the quiz's name and arduousness, the game is ...
The transformed DNA gets attached to the DNA of E.coli and radioactivity is only seen onto the bacteriophage's DNA. This mutated DNA can be passed to the next generation and the theory of Transduction came into existence. Transduction is a process in which the bacterial DNA carry the fragment of bacteriophages and pass it on the next generation.
The artificial strings of DNA do not encode for anything yet, but scientists speculate they could be designed to manufacture new proteins which could have industrial or pharmaceutical uses. [32] Experts said the synthetic DNA incorporating the unnatural base pair raises the possibility of life forms based on a different DNA code. [31] [32]
