Answer:
each new DNA double helix consists of one old strand and one new strand
Explanation:
<em>Replication </em><em>is a process during which the DNA produces a copy of itself. It is one of the steps involved in gene expression.</em>
During replication, the double helix strands of DNA are separated into individual strands by DNA helicase. Each strand then serve as a template for the synthesis of new complementary copies.
<em>After the synthesis of the complementary copies, the old strands do not wind back together. Instead, they wind with their newly synthesized complementary copies. This results in two DNA double helix with each consisting of one old strand and one new strand.</em>
This is why the replication of DNA is said to be semi-conservative.
The glandular swelling is found on the back of the earthworm and is called C.litellum.
An earthworm is tube shaped and it belongs to the Annelida phylum. It is usually found in the soil, where it contribute to the level of fertility of the soil by feeding on the dead organic matter and by aerating the soil. Earthworms lack internal skeletons and they are hermaphrodites.
The reporting of the results of any new research or findings is a necessary step. The reporting of the new discovered drug for the treatment of cancer needs to be reported in a peer-reviewed journal as well. The peer-review helps in validating the authenticity of the results of a research. Publishing the findings in a peer-reviewed journal will allow other scientists to check the findings and ensure the reliability.
Capillaries are one cell thick and so this makes them very thin. capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area.
