Detailed explanation-1: -Summary: DNA is divided up into functional units called genes, which may specify polypeptides (proteins and protein subunits) or functional RNAs (such as tRNAs and rRNAs). Information from a gene is used to build a functional product in a process called gene expression.
Detailed explanation-2: -Transcription. Transcription is when the DNA in a gene? is copied to produce an RNA? transcript called messenger RNA? (mRNA).
Detailed explanation-3: -Listen to pronunciation. (jeen ek-SPREH-shun) The process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.
Detailed explanation-4: -Which of the following statements correctly defines the process of gene expression? Gene expression is the process by which DNA directs the synthesis of proteins.
Detailed explanation-5: -A proposed updated definition A gene is a genomic sequence (DNA or RNA) directly encoding functional product molecules, either RNA or protein.
