7. Which of the following phosphates in a single-stranded DNA molecule is covalently attached to a carbon (in the deoxyribose sugar), but that phosphate is not part of a phosphodiester bond? the phosphate attached to the 5’-carbon on the first deoxyribose sugar of this single DNA strand the phosphate attached to the 5’-carbon on the last deoxyribose sugar of this single DNA strand the phosphate attached to the 3’-carbon on the first deoxyribose sugar of this single DNA strand the phosphate attached to the 3’-carbon on the last deoxyribose sugar of this single DNA strand all of the above
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

DNA - DNA is Deoxyribonucleic Acid. It is a type of nucleic acid. It is composed of two polynucleotide chains to form DNA double helical structure.
Nucleic acids are of two different types. These are:
1. DNA
2. RNA
Nucleotide - It is the monomeric unit of Nucleic acids. It is composed of :
1. Nitrogenous base
2. Phosphoric acid
3. Pentose sugar
