Answer:
reticuloendothelial system
Explanation:
The reticuloendothelial system (RES) is a heterogeneous population of phagocytic cells in systemically fixed tissues that play an important role in the clearance of particles and soluble substances in the circulation and tissues, and forms part of the immune system.
The answer is A. melting. The change from gas to liquid to solid will release energy and the change from solid to liquid to gas will absorb energy. So the other three are releasing energy.
4^3 = 64
There are 64 ways to arrange the four bases (Adenine, Thymine, Cytosine, and Guanine) into triplets (include repeats of bases as well, for e.g. AAT).
Just in case you are confused by my use of Thymine above, one thing to note is that Thymine will be replaced with Uracil in RNA.
Hope this helps! :)
Answer:Single nucleotide polymorphisms or SNPs (pronounced "snips") are DNA
sequence variations that occur when a single nucleotide (A,T,C, or G) in the
genome sequence is altered (point mutation).
SNPs do not cause disease, but they can help determine the likelihood that someone will develop a particular disease.
Because single base mutations can either create additional restriction sites or destroy pre-existing sites, DNA preparations from different individuals frequently exhibit different patterns of size distribution of restriction fragments that hybridize with a particular probe. These differences are called
restriction fragment length polymorphisms (RFLPs).
