Answer:
transformation
Explanation:
Transformation is one of the three methods of genetic recombinant in bacteria. The other two are transduction and conjugation. Transformation occurs when the bacterial cells take up the DNA and which in turn changes their phenotype.
Transformation requires that there should not be any cell to cell contact. In the experiments performed by Griffith, the heat-killed virulent S strains were mixed with live R strains. The R strain took the DNA of heat-killed S strains which in turn converted them into the virulent strains. Since this horizontal gene transfer did not include any cell-to-cell contact, he called the process transformation.
Summation that results from the cumulative effect of multiple synapses at multiple places on the neuron is designated spatial summation.
- A strategy for generating an action potential in a neuron using input from several presynaptic cells is called spatial summation. It is the algebraic addition of potentials from various input regions, typically dendrites.
- This process, known as spatial summation, occurs when inputs from several neurons combine to cause an action potential. These potentials, which are often from dendrites, are combined to produce the spatial summation.
- The likelihood that a potential will reach the threshold level required to trigger an action potential increases with the amount of excitatory postsynaptic potentials.
- Similar to this, the likelihood of attaining the threshold potential to trigger an action potential decreases as the number of inhibitory postsynaptic potentials increases.

The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
