Stem cell therapy helped Lucy fight off the extra stop protein which allowed her to make more proteins and break down deoxyadenosine normally
More Droughts, Shrinking Sea Ice, Higher Temperatures, Less Snowpack
line A is the answer because enzymes act as catalyst for chemicals reactions which means that they help speed up the production of products from a chemical reaction
The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
