A - identical twins are less likely than fraternal twins to have similarities in regard to alcoholism. The reason why this tells us about the genetics underlying addiction is because two identical twins share the completely same genetic information while fraternal twins do not. The fact that the first two share the same and higher probability for addiction tells us that it's probably a genetic influence.

Ok this is going to be a long answer lol


Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.



During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA

I hope this helps :)

Sonbull [250]

Answer:

The correct answer is "silent; codon usage".

Explanation:

Silent mutations are changes in the genome sequence that do not result in any observable change in the phenotype of the individual. A common silent mutation is the change of a nucleotide in a codon that results in another codon that is translated into the same amino acid. The fate of silent mutations over many generations is determined by the codon usage of the species. If the silent mutation results is a codon that is not normally used by the species, it is very likely that it will get lost over time.
