Terms | Definitions |
|---|---|
 Transformation | Process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria. |
| Bacteriophage | Virus that infects bacteria. |
| Nucleotide | Monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base. |
| Base Pairing | Principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine. |
| Chromatin | Granular material visible within the nucleus; consists of DNA tightly coiled around proteins. |
| Histone | Protein molecule around which DNA is tightly coiled in chromatin. |
| DNA Replication | Copying process by which a cell duplicates its DNA. |
| DNA Polymerase | Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule. |
| Gene | Sequence of DNA that codes for a protein and thus determines a trait. |
| Messenger RNA (mRNA) | RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell. |
| Ribosomal RNA (rRNA) | Type of RNA that makes up the major part of ribosomes. |
| Transfer RNA (tRNA) | Type of RNA molecule that transfers amino acids to ribosomes during protein synthesis. |
| Transcriptions | Process in which part of the nucleotide sequence of DNA is copied into a complementary sequence in RNA. |
| RNA Polymerase | Enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription. |
| Promoter | Region of DNA that indicates to an enzyme where to bind to make RNA. |
| Intron | Sequence of DNA that is not involved in coding for a protein. |
