3. The average molecular weight of human proteins is about 50,000 daltons. A few proteins are much larger, such as a muscle cell protein called titin, which has a molecular weight of 3,000,000 daltons. B) If the nucleotides in the coding portion of the mRNA constitute 5% of the total nucleotides that are transcribed, how long will it take a muscle cell to transcribe a gene for an average protein versus the titin gene. Assume that the transcription rate is 50 nucleotides per second.

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.
