Which of the following statements concerning genes are true? Select all that apply. A gene is a segment of DNA that determines a certain trait.A gene is a segment of DNA that determines a certain trait. An allele is a variation of a given gene. Genes contain information that codes only for proteins involved in the regulation of gene expression.Genes contain information that codes only for proteins involved in the regulation of gene expression. Genes are not responsible for the expression of traits.Genes are not responsible for the expression of traits. Allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.Allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.
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.
