Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.
<span>In the right atrium, the auricle and anterior wall exhibit obvious muscular ridges called MUSCULI PECTINATI.
Musculi pectinati or pectinate muscles are identified as specialized intracardiac muscle. The muscular ridges are like combs. These ridges help the right atrium dilate without much walls stress during adverse loading conditions.</span>
Detritivores role is to consume dead animals (decompose). Thus it is B
The correct option is B.
An alteration in an individual's gene may either be beneficial or detrimental. If the alteration in the gene sequence confers a genetic advantage on the individual then the alteration is beneficial but it the alteration confers a genetic disadvantage on the individual, then the alteration is detrimental.
The valves in the heart make sure that blood goes in only one direction. For example, when blood is pumped from the left ventricle the mitral valve won't allow the blood to come back into the left atrium. And the aortic valve will prevent the blood from coming back into the left atrium from the aortic arch.
