[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
A cell reads the instructions in DNA and builds a protein based on those instructions.
|
|
|
A gene is copied many times so that all of a cell’s daughter cells will have their own copy.
|
|
|
The nucleus of a cell builds cellular proteins based on the sequence of the mRNA code.
|
|
|
A single gene leaves the nucleus of a cell and travels through the cytoplasm to the membrane.

Detailed explanation-1: -Definition. Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Detailed explanation-2: -Which of the following best describes what happens during gene expression? A cell reads the instructions in DNA and builds a protein based on those instructions.
Detailed explanation-3: -During gene expression, DNA in the nucleus is received by proteins that make a copy called messenger RNA or mRNA. The mRNA is processed and transported to the cytoplasm, where ribosomes can read the message encoded and assemble the correct amino acids with the help of transfer RNA or tRNA.
Detailed explanation-4: -Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
