The termt that refers to all of an organism's proteins.
In this process, a gene's DNA is used as a template for synthesis of a specific protein.
The first process of gene expression that occurs in the nucleus in which the information encoded in a specific region of DNA is copied to produce a specific molecule of RNA.
The second process of gene expression in which the RNA attaches to a ribosome, where the information contained in RNA is translated into a corresponding sequence of amino acids to form a new protein molecule.
A sequence of three nucleotides in DNA.
Each DNA base triplet is transcribed as a complementary sequence of three nucleotides, called a _______.
The set of rules that relate the base triplet sequence of DNA to the corresponding codons of RNA and the amino acids they specify.
messenger RNA (mRNA)
The type of RNA that directs the synthesis of a protein.
ribosomal RNA (rRNA)
The type of RNA that joins with ribosomal proteins to make ribosomes.
transfer RNA (tRNA)
The type of RNA that binds to an amino acid and holds it in place on a ribosome until it is incorporated into a protein during translation.
One end of the tRNA carries a specific amino acid, and the opposite end consists of a triplet of nucleotides called an _______.
An enzyme that catalyzes transcription of DNA.
The segment of DNA where transcription begins, a special nucleotide sequence called a _______, is located near the beginning of a gene.
Transcription of the DNA strand ends at another special nucleotide sequence called a _______, which specifies the end of the gene.
Regions within a gene called _______ do not code for parts of proteins. They are located between regions called _______ that do code for segments of a protein.
Immediately after transcription, the transcript includes information from both introns and exons and is called...
small nuclear ribonucleoproteins
The introns are removed from pre-mRNA by...
A process in which the pre-mRNA transcribed from a gene is spliced in different ways to produce several different mRNAs.
Several ribosomes attached to the same mRNA.
Organisms with altered genes.
Synthetic DNA, formed by joining a fragment of DNA from one source to a portion of DNA from another.
The manufacture and manipulation of genetic material.
