The DNA bases are: Adenine Cytosine Guanine Thymine and they pair as follows: A-T G-C as for RNA the Bases are: Adenine Cytosine Guanine and Uracil and they pair as following: A-U G-C. DNA transcription occurs in the nucleus of a cell the process in a simple format occurs as such: A strand of DNA will get "unzipped" by a enzyme called DNA pelymerase adter this happens a rNA strand with corresponding base pairs will attach to this strand and then another enzyme called DNA helicase will seal the two together.

Answer:

1. Gene expression may be controlled by epigenetic mechanisms.

The base pair sequence of a gene is not solely responsible for the sequence of amino acids. A gene may have several allele/variants whose expression is controlled by multiple factors. Epigenetic processes such as DNA methylation, do not involve changes in the DNA sequence. Instead they influence the protein amino acid sequence by changes in the process of transcription or even translation.

2. The mutation introduced a stop codon into the middle of the mRNA molecule.

The protein will be shorter if the point mutation causes the creation of a stop codon in the interior of the mRNA strand. Thus, the remaining sequence after the mutation will no longer be used to create the rest of the protein.

3. Pre-mRNA is not edited, and is used as mRNA.

Because no introns and exons are included in the model, the pre-mRNA is not edited. During this step, the introns are removed from the DNA strand. However, due to the fact that the model does not define them and thus differentiate between them and the exons, the pre-mRNA will be used as mRNA.

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

The processes of translation and transcription are identical in all organisms. The only difference is the DNA sequence itself, which is species or organism specific. Thus, as it is a new beetle species, its genetic code will be unique. However, it will be translated and transcripted in the same manner as that in all other species.Their mRNA will also have and use the same nucleic acids.

5. The removes introns from pre-mRNA.

The pre-mRNA includes both introns and exons. However, only exons are used in the protein synthesis, whereas the introns are removed during the pre-mRNA stage.

6. Each of many tRNA molecules contains an anticodon, and it binds to a specific amino acid.

The anticodon of a tRNA molecule is amino acid specific. Thus, it can bind to one or a few specific mRNA codons.

7. RNA contains uracil (U) instead of thymine (T).

Both DNA and RNA have phosphate groups bound to a nitrogenous base. However, the single stranded RNA has uracil instead of the thymine found in the double stranded DNA. Also, both RNA and DNA have cytosine and guanine.

A

Explanation:

Upon discovery of the DNA structure by Watson and Crick, three models were proposed in the 1950's to explain the method in which DNA replicated. One of these models stood out, this model is the SEMICONSERVATIVE MODEL.

In the semiconservative model, it was proposed that a single DNA strand serves as a template for synthesizing its complementary strand. The cell replicates its DNA in the S-phase of interphase. In this phase, the the double-helix of the DNA is separated into two single strands. An enzyme called DNA polymerase then synthesizes a new strand complementary to each separated single strand.

At the end, the replicated double-stranded DNA now contains one old template strand and a new complementary strand.
