Genetic engineers use plasmids. A plasmid is
Viefleur [7K]

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

_____ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as _________. The ______
jolli1 [7]

Answer:

_Mitosis_ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as __meiosis__. The __parent cell_ is the cell that divides to become two new _daughter cells__.

Explanation:

The excerpt explains cell division. Let us define some of the terms used:

Mitosis: Mitosis is a stage in the cell cycle where a parent cell divides/replicates into two identical daughter cells. They are identical because they contain the same number of genetic information after division. Mitosis is responsible for cell growth in all somatic cells

Meiosis: Meiosis is a type of cell division in germ (reproductive) cells where the parent cell divides into two daughter cells which contain half the number of genetic information (haploid) as the parent cell.

Parent cell: This refers to the original cell that undergoes division into two or more daughter cells

Daughter cells: The daughter cells are the resulting cells produced after cell division.

For a better understanding of the whole cell division cycle, please read-up the stages contained in both the mitosis and meiosis.

Why must there be variation in a population in order for natural selection to occur?
olga_2 [115]
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. If there is no variation, then all individuals have the same chance to survive and nothing will be particularly selected.
