PLEASEEEE HELPPPPPPPPPPP

Professor Marcus has identified a new species of beetle in the Amazon Rainforest. The professor then investigates the process of gene expression in the cells of the beetle. Which is an expected result of the investigation?

A The processes of transcription and translation are unique in the beetle.

B The process of translation in the beetle is similar to other organisms, but involves a unique genetic code.

C The process of transcription in the beetle is similar to other organisms, but involves a unique set of nucleic acids in mRNA.

D The processes of transcription and translation, including the genetic code, are the same in the beetle as in nearly all other organisms.

Answer 1

D The processes of transcription and translation, including the genetic code, are the same in the beetle as in nearly all other organisms.

Step-by-step explanation:

Transcription is the cellular process where a specific DNA fragment called 'gene' is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes. In eukaryotic organisms such as, in this case, beetles, both transcription and translation are essentially the same processes, and the genetic code used in the protein synthesis is also the same. The difference between beetles is the variation among DNA nucleotide sequences (genomes) which are used as templates to synthesize mRNAs, thereby their final products (proteins) are also different.
