Nature highlights three key graphics from the week in science and research.
This graphic illustrates two types of mutation that can occur in genes. DNA is transcribed into messenger RNA, which is translated into protein. DNA mutations can be synonymous , meaning that they have no effect on the sequence of the protein that the gene encodes, or they can be non-synonymous , indicating that they alter at least one amino acid.
They found that, on average, both mutation types reduce the amount of mRNA produced from a gene compared with that produced from the original DNA sequence. Both also reduce the fitness of yeast cells, says this

Improving recombinant protein production by yeast through genome-scale modeling using proteome constraints - Nature CommunicationsDue to the complexity of the protein secretory pathway, strategy suitable for the production of a certain recombination protein cannot be generalized. Here, the authors construct a proteome-constrained genome-scale protein secretory model for yeast and show its application in the production of different misfolded or recombinant proteins.
