<span>Exons from the same gene (like you said above) could be spliced in different ways to make different 'mRNAs'.</span>
Instructions from characteristics which are passed from the
parent to the offspring are called genes. Genes are made of complex molecules
of DNA. Each parent also donates chromosomes to their offspring. Each offspring
will get half of their genes from each parent and they will therefore have the aspect
of the two parents.
<span>During protein synthesis the exons are joined together to form a sequence of for a functional protein.
Before the mRNA can undergo the process of translation in the cytoplams it undergoes a process called RNA splicing. This process produces a 'final draft' of the mRNA before translation gets under way. The process involves the removal of introns (non-coding sequences) and joining of exons in eukaryotic mRNA.</span>
<span>D increasing the accumulation of organic materials
NOT:
</span>A decreasing the potential for soil erosion
B increasing the food available for consumers
<span>C decreasing the nutrients available for new plants</span>
