Which sentence is correct? All cells have the same genes, but different genes are active in different cells. Lungs look differen
t from the heart because the cells that make up these organs have different genes. All cells have the same genes, and all of a cell's genes are active at the same time. As cells and tissues differentiate, they lose some of their genes.
All cells have samegenes, but different genes are active in differentcells
<u>Explanation:</u>
Most living organisms are made up of different kinds of cells specialize in performing various functions like nerve cells perform differentfunctions than bloodcells. But all the cells are composed of same set of genetic information.
Since biochemical function is found out mainly by some specific enzymes, different sets of genes must be turned on and off in the various cell types to perform different functions. This is how cells differentiate for different functional capabilities.
the reduction in the sequence is as a result of the removal of introns. Introns are actually non-coding regions and do not code for proteins. they are usually spliced out.
