The segments of DNA that are the units of inheritance.

DNA replication occurs during this phase of the cell cycle.

Transcription in the process of producing mRNA in this location of the cell.

Molecules in the cytoplasm pick up the amino acids.

A whole new science where scientists study DNA molecules and make changes in the DNA.

These individuals are given the credit for proposing the "double helix" model of DNA.

DNA replication occurs in this area of the cell.

A sequence of three bases on a mRNA molecule that codes for an amino acid.

Translation occurs in this location of the cell.

Technique used to separate the DNA from the rest of the cell.

Each nucleotide in DNA consists of these 3 components.

These bonds are broken between the bases in DNA replication.

In RNA, adenine (A) joins with this nitrogenous base.

These smaller molecules are linked together to form a polypeptide chain.

Pieces of DNA are called fragments and can be separated using this process.

This nucleic acid is double stranded and contains the original genetic code.

In DNA, adenine (A) joins to this nitrogenous base.

In RNA, cytosine (C) joins with this nitrogenous base.

In the first step of translation, this molecule attaches to the ribosome.

Takes short pieces of DNA from one organism and joins it to the DNA of a completely different organism which can be placed back into a living cell by transformation.

This nucleic acid is single stranded and contains the a copy of the genetic code.

In DNA, guanine (G) joins to this nitrogenous base.

The completed mRNA molecule leaves the nucleus through the nuclear membrane and moves to this area of the cell.

Amino acids are held together with these type of bonds.

If an organism contains genes from a different organism, they are called
