| (ribonucleic acid) is a nucleic acid- a molecule made of nucleotides linked together. |
|

Term
|
Definition
| abbreviated as U. Is complementary to adenine whenever RNA base-pairing with anothernucleic acid. |
|
|
Term
|
Definition
The instructions for making a protein are transferred from a gene to an RNA molecule in a process. |
|
|
Term
|
Definition
| Cells then use two different types of RNA to read the instruction on the RNA molecule and put together the amino acid that male up the protein in a process. |
|
|
Term
|
Definition
| the entire process by which protein are made based on the information encoded in DNA. |
|
|
Term
|
Definition
An enzyme that adds and links complementary RNA nucleotides during transcription. |
|
|
Term
| First Step of transfer of information from DNA to RNA |
|
Definition
Transcription begins when RNA polymerase binds to the gene's promoter- a specific sequence of DNA that acts as a "start" singal for transcription. |
|
|
Term
| Second Step of transfer of information from DNA to RNA |
|
Definition
| RNA polymerase then unwinds and separates the two strands of the double helix, exposing the DNA nucleotides on each strand. |
|
|
Term
Third Step of transfer of information from DNA to RNA |
|
Definition
complementary RNA nucleotides are added. U=A, C=G (Uracil= Adenine, Cytosine=Guanine) (on thymine) |
|
|
Term
|
Definition
| is a form of RNA that carries the instructions for a protein from a gene and delivers it to the site of translation. |
|
|
Term
|
Definition
| The RNA instructions are written as a series of three- nucleotides sequences on the mRNA. |
|
|
Term
|
Definition
The amino acids and "start" and "stop" singals that are coded for by each of the possible 64 mRNA codons. |
|
|
Term
|
Definition
| (tRNA) molecules are single strands of RNA that temporarily carry a speific amino acid on one end. |
|
|
Term
|
Definition
| Is a three- nucleotide sequence on a tRNA that is complementaryto an mRNA. |
|
|
Term
|
Definition
| (rRNA) molecules are RNA molecules that are part of the structure of ribosomes. |
|
|
Term
| First Step of RNA's Role in Translation |
|
Definition
| The ribosomal subunits, the mRNA, and the tRNA carrying methionine bind together. |
|
|
Term
Second Step of RNA's Roles in Translation |
|
Definition
| The tRNA carrying the amino acid specified by the codon in the A site arrives. |
|
|
Term
Third Step of RNA's Role in Translation |
|
Definition
A peptide bond forms between adjacent amino acids. |
|
|
Term
| Fourth Step of RNA's Role in Translation |
|
Definition
| The tRNA in the P site detaches and leaves its amino acid behind. |
|
|
Term
Fith Step of RNA's Role in Translation |
|
Definition
| The tRNA in the A site moves to the P site. The tRNA carrying the amino acid specified by the codon in the A site arrives. |
|
|
Term
| Sixth Step of RNA's Role in Translation |
|
Definition
| A peptide bond is fromed. The tRNA in the P site detaches and leaves its amino acid behind. |
|
|
Term
| Seventh Step of RNA's Role in Translation |
|
Definition
| The process is repeated until a stop codon is retached. The ribosome complex falls apart. The newly made protein is released. |
