During transcription, only some of the DNA bases are transcribed. What parts of the DNA or/and protein(s) determines which part of the genome is transcribed into mRNA?
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.
During transcription, only some of the DNA bases are transcribed. What parts of the DNA or/and protein(s) determines which part of the genome is transcribed into mRNA?
Transcription is the first step in gene expression, the process by which genetic information is converted into a functional product, such as a protein. During transcription, the information stored in DNA is copied into a complementary molecule of RNA (messenger RNA, or mRNA). This mRNA molecule serves as a template for the production of a protein, which occurs during a subsequent process called translation.
Transcription is performed by an enzyme called RNA polymerase, which reads the DNA sequence and synthesizes a complementary RNA molecule. The RNA polymerase starts at a specific site on the DNA, called the promoter, and moves along the strand, adding nucleotides to the growing RNA molecule. When the RNA polymerase reaches a termination signal, it stops transcription and releases the completed mRNA molecule.
