Which best describes the outcome of dna replication? the new dna molecule consists of one strand of dna. the new dna molecule accumulates a new strand of dna with each replication. the new dna molecule consists of one new strand and one old strand of dna. the new dna molecule contains new dna, and the old molecule keeps the old dna

The correct answer is -

The new DNA molecule consists of one new strand and one old strand of DNA.

DNA replication is a process of formation of two molecules of DNA from a single DNA molecule (which is double stranded).

In this process, the two DNA strands of the original DNA are first separated so that the template strands are exposed.

Using the template strands, enzyme DNA polymerase adds nucleotides (in the direction 5' to 3') in a complementary manner-

For adenine, thymine, guanine, and cytosine in the template strand, thymine adenine, cytosine, and guanine are added respectively.

The new DNA molecule consists of one new strand and one old strand of DNA. That is why, it is also called semiconservative replication.

Thus, option third is the right answer.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
