Blood taken from Raymond is injected into Fred, causing increased transcription of red protein in Fred's cells You take a sample of Raymond's blood, mix it with a 50-50 mix of water and oil. Injecting the water fraction into Fred has no effect, while injecting the oil fraction causes increased transcription of red protein in Fred's cells. The chemical agent causing these effects in Fred is most probably O #3 A sterold hormone O #1 Acting via CAMP O #2 Binding to a plasma membrane-bound receptor on Fred's cells O #1 and #2 O #1, #2 and #3

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.
