The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.

Why must cells be able to both transcribe and replicate their DNA? (2 points)
Artemon [7]

Answer: The correct answer is D) Replication creates new DNA while transcription creates mRNA.

Replication is a genetic process in which DNA ( deoxyribonucleic acid) is duplicated so that two copies of the genetic material is prepared. This is important for cell division.

Transcription is a process, which includes copying of the genetic formation from DNA into mRNA ( messenger RNA). This provides instructions for the synthesis of specific proteins.

Thus, the correct option is D)
