Inquiry Into Life (16th Edition) ISBN:9781260231700 Author:Sylvia S. Mader, Michael Windelspecht Publisher:McGraw Hill Education Which of the following statement about DNA is correct?DNA has a double-helical structure with two nucleotide chains that run anti-parallel, the outer edges are formed by alternating deoxyribose sugar molecules and phosphate groups, which make up the sugar-phosphate backbone. Hence statement 3 is correct.
Which of the following statement is false about DNA?The answer choice that is false is d.
The DNA of cells, whether prokaryotic or eukaryotic, consists of two strands of nucleotides that twist into a double helix. Some viruses, which are not cellular entities, have genomes of single stranded DNA.
Which one of the following statement is incorrect for Z DNA?Which one of the following statement is INCORRECT for Z-DNA? Explanation: Anti glycosidic bond conformation is incorrect as in Z-DNA the sugar and glycosidic bond conformations alternate, anti for C and syn for G while in B form there is only anti glycosidic bond conformation.
Which of the following describe the DNA?Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
