<span>The most obvious patter is that A binds with T and C with G, as is the case with DNA.
The beginning of DNA transcription starts with the binding of the enzyme RNA polymerase to the promoter region. Next, RNA moves begins transcribing in the 5' to 3' direction using one strand of DNA as the template strand. This strand of RNA produced is complimentary with the other strand known as the coding strand except that Thymine is replaced by Uracil. To cleave the strand Bacteria can use what is known as Rho-independent termination where the strand makes a hairpin loop that causes stress and breakage. Or Rho-dependent termination where a protein causes an interaction between the template and mRNA and they disassociate. Termination is not really understood in eukaryotic organisms.</span><span>

The answer is algae.
Plankton includes a diverse group of organisms that live in the water, but are not capable of active swimming against the current. Therefore, since shark, squid and crab can swim and algae cannot, <span>among these groups </span>only algae can be a plankton.
Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication.
Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Human DNA has around 3 billion bases, and more than 99 percent of those bases are the same in all people. DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA
Keeping constant the number of chromosomes of the species and perform a summary of recombination, through crossing-over
( Swapping – increases the <span>genetic variability )</span>
hope this helps!
