During a controlled experiment, a scientist will isolate and test (D) a single variable. A conclusion, nor a mass of information can be isolated or tested. A control group is the group that would receive a placebo, so testing that would be futile.
The part of a DNA molecule responsible for the direct coding of specific traits in an organism is the nucleotide sequence.
<h3>How is a DNA molecule structured?</h3>
The DNA molecule is the biological molecule that stores genetic information in living organisms.
The DNA molecule is made up of three major components in its structure:
- Five carbon sugar
- Nucleotide bases
- Phosphate group
The five carbon sugar is deoxyribose while the nucleotide bases are four in number as follows:
- Adenine
- Guanine
- Thymine
- Cytosine
These nucleotides are responsible for the direct coding of specific traits in an organism.

Answer:
<h2>The Cornea in the ear</h2>
Explanation:
is the parts of the human body that get oxygen directly from the air and not from the blood
Answer:
The correct answer will be- codons and each codon specific for amino acids.
Explanation:
Deoxyribose nucleic acid is the genetic material of the organism which provides instructions for the organism. DNA is made up of nucleotide monomers which are composed of five-carbon sugar deoxyribose, a phosphate group and four types of nitrogenous bases (adenine, guanine, cytosine and thymine).
It is the arrangement of these nitrogenous bases which provide codes to the organism as it forms mRNA molecule through transcription. The sequence of the nitrogenous bases in mRNA is read by the ribosome during translation.
The ribosome reads the bases in triplets called "codon" which code for a specific amino acid. If the sequence of the base changes, therefore, the amino acid also changes. These amino acids bond to each other by peptide bond and form a protein molecule.
