The offspring of sexual reproduction:
|
receives half of its genetic material from each parent.
|
|
The offspring of asexual reproduction:
|
receives all of its genetic material from one parent.

Using special enzymes, scientists have been able to isolate the gene that controls the production of Protein A from one type of bacteria and insert the gene into another type of bacteria that does not normally produce Protein A. These bacteria then produce Protein A. What is the name of this technique?
|
genetic modification
|
|
A ________ is a piece of DNA that contains instructions for the manufacturing of a protein.
|
nitrogen base
|
|
Prior to cell division, the cell’s DNA copies itself during ____ of the cell cycle.
|
interphase
|
|
The process of using DNA as a template to make more DNA is known as ___________.

Before the strands of DNA can separate, the DNA must unwind and the bonds between the _________
must be broken. |
nitrogen bases

Four stages in the production of protein molecules in a cell are listed below.
1 - Transfer RNA molecules bring amino acids to the ribosome. 2 - DNA molecules serve as templates for messenger RNA molecules. 3 - Messenger RNA molecules move to ribosomes. 4 - A chain of amino acids forms on the ribosome. Which sequence best represents the correct order of these stages? |
2 – 3 – 1 – 4
