in your DNA. Deoxyribonucleic Acid (DNA) is the hereditary material in humans and almost all other organisms, containing the biological instructions that make each species unique. DNA, first identified in the late 19th century and structure as a double helix was discovered in 1953 by Watson and Crick, is present in the nucleus of every cell in an organism. It's estimated that if unwound and linked together, the strands of DNA in one cell would stretch almost 6 feet in length. For many years, the complexity of DNA made understanding the full of its influence a distant dream. However, with the of advanced genomic technologies, scientists have made groundbreaking strides in understanding and mapping the human genome.

Correct answer: lie
Explanation: The verb 'lie' is used here to indicate the position or location of the roots of these traits, fitting grammatically as it aligns with the subject 'roots' and is in the correct tense. It also matches the context of discussing where these traits are found, making it the most appropriate choice.
Meaning: 'Lie' means to be situated or located in a particular place, which in this context refers to the roots of traits being located in DNA.
Wrong options:
- reside: While 'reside' can mean to live or be situated, it is more commonly used for people or animals, making it less suitable here.
- found: The word 'found' implies discovery rather than location, which does not fit the intended meaning of where the roots are situated.
- pour: 'Pour' refers to a liquid being transferred from one container to another, which is completely unrelated to the context of traits and DNA.
Correct answer: whose
Explanation: The word 'whose' is a possessive pronoun that correctly links the structure of DNA to its discovery, fitting grammatically as it indicates ownership of the structure by DNA. It also maintains the flow of the sentence, making it contextually appropriate.
Meaning: 'Whose' is used to indicate that something belongs to or is associated with someone or something, in this case, the structure belonging to DNA.
Wrong options:
- which: 'Which' is a relative pronoun but does not convey possession, making it less suitable in this context.
- its: 'Its' is a possessive pronoun but does not fit grammatically as it would require a noun following it to clarify what is being referred to.
- this: 'This' is a demonstrative pronoun that indicates a specific thing but does not convey the possessive relationship needed in this sentence.
Correct answer: extent
Explanation: The noun 'extent' refers to the degree or scope of something, which fits grammatically and contextually as it describes the range of DNA's influence. It aligns with the overall theme of understanding the complexity of DNA.
Meaning: 'Extent' means the range, area, or degree to which something exists or is relevant, in this case, the influence of DNA.
Wrong options:
- trait: 'Trait' refers to a characteristic or feature, which does not fit the context of discussing the overall influence of DNA.
- intention: 'Intention' refers to a purpose or plan, which is unrelated to the context of DNA's influence.
- circumstance: 'Circumstance' refers to a condition or fact that affects a situation, which does not accurately describe the scope of DNA's influence.
Correct answer: advent
Explanation: The noun 'advent' signifies the arrival or introduction of something significant, fitting grammatically as it indicates a new phase in genomic technologies. It also aligns with the context of advancements in science.
Meaning: 'Advent' means the arrival or beginning of something, particularly something important, in this case, advanced genomic technologies.
Wrong options:
- recovery: 'Recovery' refers to the process of regaining something lost, which does not fit the context of advancements in technology.
- strategy: 'Strategy' refers to a plan of action, which does not align with the context of the introduction of new technologies.
- constituency: 'Constituency' refers to a body of voters or supporters, which is unrelated to the context of scientific advancements.
