Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Answer:
It helps the plant retain water.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". It is composed of cutin, a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water.
Answer and Explanation:
In a cell, the smaller the surface area in relation to its volume, the lower the rate of diffusion. The ratio of surface area to volume of an object decreases sharply with increase in its size. The materials move across the cell rapidly because the cell has a larger surface area to volume ratio thus the rate of diffusion of materials is high.
Answer;
-Vertical relationship
Explanation;
-Vertical relationships are up down relationships between superiors and inferiors, the only way this relationship is valid is if it is educational and the person on top has more wisdom and knowledge than the person on the bottom.
-Vertical relationships use feminine communication rituals where the subordinate must be pleasant and must not communicate negative emotional data to the superior.
-Horizontal relationships on the other hand, are democratic educational relationships between people that are relatively equal in knowledge, wisdom, or technique.
Answer:
C. A small, circular piece of DNA
Explanation:
A plasmid, usually circular but sometimes linear, is a small double-stranded DNA unit, which is chromosome independent and is capable of self-replication. Each plasmid carries only a few genes. Carrying only a few genes, the plasmid’s size ranges from 1 to more than 1000 kbp. Genes required for organism survival and those that are generally beneficial to the host organism, such as antibiotic resistance, are often found in plasmids [1].
Mostly plasmids can be found in bacteria, but they are also present in multicellular organisms and archaea. Plasmids usually contain at least one gene and are not considered independent life forms even though they possess separate genes from their hosts
