codon: A three-base mRNA sequence. This sequence is made up of a DNA triplet and three corresponding nitrogenous bases in a mRNA strand.
exons: During RNA processing, a strand of mRNA is "edited", leaving behind these remaining segments. These segments are then spliced together to create a shorter, more functional strand of mRNA.
chromatin: A tangle of fine filaments formed by the loose coiling of nucleosomes within the nucleus, which only occurs in cells that are not dividing. This tangle of fine filaments gives the cell's nucleus a clumped and grainy look.
gene activation: The factors that control the process of uncoiling a DNA molecule, and temporarily removing its histones. When the weak bonds between nitrogenous bases of the two DNA strands are disrupted, and the histone that guards the promoter is removed these factors will come into play. These factors are only somewhat understood.
ribosome: The organelle that makes proteins. This organelle makes proteins when it uses the information from the DNA that is stored in the nucleus of the cell. This organelle consists of RNA and proteins. There are two functional types of this organelle.
transcription: The process that produces DNA from an RNA template. The three types of RNA are formed through this process. This process mainly involves the RNA polymerase rendering from the gene.
introns: The segments that are removed from an mRNA strand during RNA processing. These useless segments are cut out of the mRNA strand before it exits the nucleus to conduct protein synthesis.
genetic code: The course of storing information in the strands of DNA in the nucleus. Also known as a triplet code because a sequence of three nitrogenous bases gives an amino acid a specific identity. Understanding this method allows scientists to determine how cells build proteins, and how different characteristics are inherited.
RNA polymerase: The enzyme that binds to the promoter of a gene. This occurs in the first step of transcription.
translation: The process that uses information provided by an mRNA strand to form a linear chain of amino acids. This process occurs at a ribosome. During this process, the sequence of codons will specify the sequence of amino acids in the polypeptide.
anticodon: The base sequence of this tells you which type of amino acid is carried by the tRNA. This molecule is formed by a tight chain of nucleotides that forms a loop, containing three nitrogenous bases.
histones: The proteins that nucleoli are composed of. Nucleoli are made up of enzymes, RNA, and these proteins.
chromosome: Each one of these contains strands of DNA bound to histones. When one of these is added with another, they form 23 pairs located in the nuclei of somatic cells. Each one of these contains the DNA needed for protein synthesis.
DNA: Located in the nucleus, this type of nucleic acid molecule determines our inherited characteristics, controls the manufacturing of enzymes, and regulates all aspects of our cells' metabolism.
coding strand: One of the two strands of DNA in a gene. This strand holds the triplets that specify the sequence of amino acids inside of the polypeptide.
mRNA: This type of RNA carries the information needed for protein synthesis. Activated genes pass their information to this type of RNA in order for protein synthesis to occur correctly.
mutation: The permanent change in a cell's DNA that affects a nucleotide sequence of one, if not more, genes. This permanent change occurs during DNA replication.
template strand: One of the two strands of DNA in a gene. This strand contains complementary triplets that are used in mRNA production as a template.
protein synthesis: The process that assembles functional polypeptides inside of the cytoplasm. This process occurs through translation.
gene: The functional unit of heredity. All of the DNA triplets that are necessary to produce one specific protein are contained in this. Every one of these contains segments that are responsible for regulating its own activity.
tRNA: This type of RNA provides amino acids during translation. Each molecule of this type of RNA will bind and deliver a specific type of amino acid. There are more than 20 types of this kind of RNA.
centromere: The single point at which two chromatids are connected. This point is surrounded by a protein complex known as kinetochore.
promoter: A special region of DNA that is responsible for regulating its own activity. This control segment is formed at the start of each gene.
