Answer:
The process where part of the DNA is saved during replication is known as semi conservative replication.
Explanation:
During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid). When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied during the cell division cycle. During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus
of a cell during the s stage of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.
Answer:
Red blood cells, root hair cells in plants
Explanation:
Red blood cell: it has no nucleus. It offers the cell to carry more hemoglobin
Root hair cells in plants: they have a large cytoplasm which enables them to take water from the soil.
A hypersensitive reaction to a specific antigen in the environment is a(n) _ALLERGY_.
Answer:
The force of friction is reduced between the blocks by adding the dishwashing liquid because the liquid is slippery and this makes it difficult for the two surfaces to contact each other directly. Therefore the blocks slip past each other rather than grinding against each other, producing less friction.
