A nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds between nucleotides of nucleic acids. Nucleases variously effect single and double stranded breaks in their target molecules. In living organisms, they are essential machinery for many aspects of DNA repair. Defects in certain nucleases can cause genetic instability or immunodeficiency.[1] Nucleases are also extensively used in molecular cloning.[2]

Depiction of the restriction enzyme (endonuclease) HindIII cleaving a double-stranded DNA molecule at a valid restriction site (5'–A|AGCTT–3').

There are two primary classifications based on the locus of activity. Exonucleases digest nucleic acids from the ends. Endonucleases act on regions in the middle of target molecules. They are further subcategorized as deoxyribonucleases and ribonucleases. The former acts on DNA, the latter on RNA.[2]

The correct answer is B, I know this because none of the other answers are even reasonable. For example-
A is wrong because the size of elephant tusk has not changed over time, elephant tusk just grow...
C is wrong because it makes no sense to hunt elephants with no tusk :/
D is completely wrong because tusk have nothing to do with reproduction, those are two completely separate bodily functions.........

Genes, which are the molecular units of heredity, are composed of specific sequences of four different__________.

Mashcka [7]

Answer:

Nucleotide bases.

Explanation:

Unique sequences of bases makes up a nucleotide. These nucleotide sequencing are used by DNA as a genetic code of information that determines type of cells, proteins and the whole organismal structure.

There are four nucleotide bases, Adenine and guanine termed purines are big, cytosine and thymine called pyrimidines are small. A purine pairs with a pyrimidine, such that adenine pairs with thymine and guanine pairs with cytosine. The bases are the same but each DNA uniqueness lies in the sequence of base pairing.

Natali [406]

Answer:

The correct answer is E) eutely

Explanation:

Nematodes are organisms with bilateral symmetry, although their organs are coiled, sometimes one of the limbs is lost and many of sedentary life tend to radial symmetry. One of the most striking characteristics of these animals is that their growth is not produced by an increase in the number of cells that compose them, but by an increase in the size of the already existing cells; in fact, in most adult tissues the number of cells is constant, a phenomenon known as eutelia.

Eutelia is the condition of an organism composed of a constant number of cells or syncytial nuclei in all adult individuals of a species, such as nematodes, it means that body growth is not carried out by increasing the number of cells but by the growth of existing cells.
