<em>sieve tube elements are the cells of phloem which allow transportation of photosynthates through phloem...
<u>
how sieve tube elements form sieve tubes:
</u>sieve tube elements are connected end to end and form a long chain which is called sieve tube,,,,
sieve tube elements are connected with the help of a side chain with the help of peptide bond...also one element has tapering end which easily overlaps with other end of next element to form sieve tube,,,,</em>

Explanation:
Answer:
each of the two daughter DNA molecules contains one strand from the original DNA molecule and one newly synthesized strand.
Explanation:
DNA replication is a semi-conservative process. The two parental DNA strands are separated from each other by the action of helicases. The separated DNA strands serve as the template. Primase enzyme forms primers which are elongated by DNA polymerase enzymes. These enzymes elongate the primer by the addition of deoxynucleotides complementary to the sequence of the template DNA strand.
Therefore, DNA replication forms two DNA double helices from one parental DNA molecule. Each of the daughter DNA molecules contains one parental DNA strand and one newly formed DNA strand making the process semi-conservative.
