EOC Domain 2: Genetics

Several enzymes work together to separate the DNA and add complementary bases to each strand

A cell sends a molecule into a different cell, where this molecule can bind to the DNA and create an exact copy

The DNA separates itself unaided and uses nearby nitrogen bases and binds them to itself

A bacteria invades the cell and causes it to duplicate all of its DNA as an immune response

A-B-C-D

B-C-A-D

C-B-A-D

D-B-A-C

Different cells in a multicellular organism all have the same DNA, but cells can express different proteins

Different cells in a multicellular organism all have different DNA

DNA becomes mutated depending on the cell type that it is found in

Cells can fuse to become different kinds of cells. Cells that fuse more become more complex

Meiosis produces identical daughter cells without variation.

Identical offspring may result in extinction in an unstable environment

Combining of genetic material during reproduction may lead to harmful mutations

The amount of energy needed to reproduce is low

Two parents are required, and mates aren't always available

Using a high nitrogen fertilzer.

Using herbicide to get rid of weeds.

Genetic modification of rice plants that are pest resistant and to produce vitamins

Using pesticide to get rid of pests that can harm the crop.
