Which of the following statements is not true? Which of the following statements is not true? Compared to whole-genome sequencing, the map-based approach is somewhat cumbersome and time-consuming. Alignment can be difficult in repetitive regions of the genome. Whole-genome sequencing relies on the generation of non-overlapping fragments that are sequenced and aligned to form contigs. Whole-genome sequencing has become the most common method for assembling genomes, with map-based cloning being used to resolve the problems often encountered during whole-genome sequencing.

Whole-genome sequencing relies on the generation of non-overlapping fragments that are sequenced and aligned to form contigs.

Explanation:

In complete genome sequencing, a DNA sample is taken from an individual and the identity of each of the three billion nucleotides that make up the human genome is determined.

DNA sequencing means determining the order of the four basic chemical components, called bases, that make up the DNA molecule.  

In the DNA double helix, the four chemical bases always unite with the same pair to form base pairs. Adenine (A) is always paired with thymine (T); cytosine (C) is always paired with guanine (G). This pairing is the basis for the mechanism by which DNA molecules are copied when cells divide, and is also the basis for the methods used in most DNA sequencing experiments.

explanation:

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
