Re: 'Evolution'-the most retarded myth ever.

... genetic information. Neofunctionalization for the most part is delusional (look at someone with trisomy). CF, PKU, sickle cell anemia- ONE base substitutions. Teachers INTENTIONALLY omit that sickle cell trait- a 'beneficial' mutation- is a LOSS of function mutation. The beta globin protein ...

Codon help?

How do I figure this out? Mutational changes were induced in a single codon in the gene of T4 phage. The following amino acid substitutions were observed. By following the base changes in the codons, determine the codon for each mutant. Assume each amino acid substitution resulted from ...

Transcripts analysis

What was the vector you used? Are they both the same? and how was the mutant made? is it deletions or substitutions? Was the one transgene integrated into the genome perhaps? How did you quantify the transcripts? perhaps the vector was not being being replicated thru the cell ...

Re: I am afraid to ask but, High school freshman - Honors Class

... she is being taught is going to leave her behind. This is especially troubeling to me since this is the field she wishes to work in. 1. Base-pair substitutions involving the third base of a codon are unlikely to result in an error in the polypeptide, this is because? A. substitutions are corrected ...
