7 0

Answer:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur.

2. Its ability to catenate; its ability to form bonds easily with other elements such as hydrogen, oxygen and nitrogen; its ability to form single, double and triple.

3. Carbohydrates, Proteins, Lipids, and Nucleic acids

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Proteins are considered polymers while Lipids are not because proteins are composed of monomeric subunits of amino acids whereas lipids do not have monomeric subunits.

Explanation:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur as they are found in many structures of living organisms- in proteins, carbohydrates, nucleic acids and lipids.

2. Carbon has the ability to form different large and complex structures because:

(I) its ability to catenate which is the ability to combine with one another to form straight, branched chain or ring compounds containing many carbon atoms.

(ii) carbon can form single, double and triple with itself and other life elements.

(iii) the relative stability of the covalent bonds formed by carbon.

3. Four groups of organic compounds found in living things are Carbohydrates, Proteins, Lipids, and Nucleic acids.

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Polymers are large molecular weight compounds built up from subunits called monomers.

Proteins are considered polymers because they are large molecular weight molecules composed of monomeric subunits of amino acids.

Lipids are not considered polymers because individually, they are not very large molecules and do not have monomeric subunits rather are composed of long fatty acids chains linked to a glycerol molecule.

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.
