Which is a difference between B-DNA and A-DNA? A. For polynucleotide strands containing the same number of nucleotides, the B-DNA strand will be shorter from end-to-end than the corresponding A-DNA. B. Both are helical, but B-DNA is right-handed and A-DNA is left-handed. C. The sugar in A-DNA is more oxidized than that in B-DNA D. Helical structures in RNA predominantly adopt the B-DNA conformation. E. None of the above. The tetranucleotide AGTC (in DNA) has a free hydroxyl group on ____. A. A B. G, T, and C C. C D. A, G, T, and C
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.
