Answer:
A) They only replicate the same time as the larger chromosome.
Explanation:
- Plasmids are small, circular, double stranded DNA molecule, which can replicate independently from its chromosomal DNA.
- If plasmids are used for experiments, they are called vectors.
- Scientists use plasmids as tools for cloning, transferring and manipulating genes.
- They are distinct from chromosomes in being non-essential.
- Plasmids are sometimes present in archaea and eukaryotic organisms.
- Plasmids often carry genes that benefit the survival of the organism, such as by providing antibiotic resistance.
- They do not replicate the same time as the larger chromosome.
The correct answer is C because a frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three

<span>RATIONALE: </span>
<span>The patient with chronic obstructive pulmonary disease (COPD) develops a barrel chest over time because trapped air enlarges the lungs and thoracic cavity, thereby reducing chest flexibility. Sunken chest, also known as funnel chest or pectus excavatum, is not related to COPD. Hyperventilation is not characteristically seen with COPD. Instead, the patient usually displays persistent dyspnea on exertion, with or without a chronic cough. Circumoral cyanosis is a bluish discoloration of the skin surrounding the mouth. It is usually an indication of a severely diminished level of oxygen and respiratory distress. Circumoral cyanosis can result from a variety of respiratory diseases and may be a late sign of the COPD disease process.

Answer:
A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away). A movement of the body part back toward the midline (i.e., to the anatomical position) is known as adduction.
