I think this means that nucleotide sequences at the restriction sites are the same when read forward or backward. Restriction sites, or restriction recognition sites, are locations on a DNA molecule containing specific (4-8 base pairs in length) sequences of nucleotides, which are recognized by restriction enzymes. Palindromic sequence is a nucleic acid sequence on double-stranded DNA or RNA wherein reading 5' to 3' forward on one strand matches the sequence reading 5' to 3' on the complementary strand with which it forms a double strand.
Answer: three types of neuron are ;sensory,interneuron and motor neurons
Explanation:
The three types of neurons are
Motor neurons
Interneurons
Sensory neurons
Sensory neurons- it receives impulses and carry them from the sense organs to the spinal cord or brain
Interneurons-it connects sensory
Motor neurons-it interprets the impulse only in the brain and spinal cord
Answer: B) seeding
Explanation:
The seeding is a process of addition of microorganisms to the oil spill so that the microorganisms eat up the components of the oil or degrade or convert the oil into a form which helps in reducing the pollution caused by the oil spills. This is an ideal approach to clean up the oil spills from the water body. The microbes will colonize in short period of time and will degrade the oil spill efficiently.
The given situation is indicating towards the seeding of the non-indigenous microbes for degrading the oil.
The last 3 statements are correct. Positive will repel positive and negative will repel negative. Positive and negative particles both attract to opposite particles and neutral is also attracted by both.
