A geneticist isolates a gene for a specific trait under study She also isolates the corresponding mRNA Upon comparison, the mRNA
olga nikolaevna [1]

Answer:

C) no, the final mRNA contains only exons, the introns were removed

Explanation:

Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.

RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a  mature mRNA.

So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.

Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.

Describe how carbon skeletons may vary, and explain how this variation contributes to the diversity and complexity of organic mo
Alecsey [184]

Carbon skeletons may vary in length, shape, number and location of double bonds and other elements covalently bonded to available sites.

A carbon atom contains four valence electrons thus, exhibiting a strong tendency to make covalent bonds with other atoms so as to complete its octet. Covalent bonds join carbon atoms together in long chains that create the skeletal framework for organic molecules.

A carbon atom could be linked to as many as four additional carbon atoms in an organic compound. Carbon atoms can also quickly form double bonds (where four electrons are shared among two atoms) and triple bonds (where six electrons are shared).

This variation in carbon skeletons contributes to the diversity and complexity of organic molecules.

Today I.d.k what to ask. I asked what is wrong with me because I am lactose intolerance, and basically I hate milk, and why are
harina [27]
Our bodies produce an enzyme called lactase. This enzyme helps our bodies digest lactose (a sugar found in milk). As we age, the amount of lactase our bodies produce decreases. Some people don’t produce as much as others. If you are lactose intolerant, it means your body doesn’t produce a lot of lactase. One option is to drink milk with lactase added to it.
Example: Lactaid
