Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A characteristic that is encoded in DNA.
A
genome
B
sex-linked gene
C
genetic trait
D
down syndrome
Explanation: 

Detailed explanation-1: -Characteristics that are encoded in DNA are called genetic traits. Different types of human traits are inherited in different ways. Some human traits have simple inheritance patterns like the traits that Gregor Mendel studied in pea plants. Other human traits have more complex inheritance patterns.

Detailed explanation-2: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.

Detailed explanation-3: -Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure). A given trait is part of an individual’s overall phenotype.

Detailed explanation-4: -Genetic Code Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T)-in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.

Detailed explanation-5: -Answer and Explanation: A gene is the component of DNA that specifies the traits of an organism. Genes are specific sequences of nucleotides that encode for the expression of different observed characteristics, or traits.
