Terms : Hide Images
7919646763nucleotidesmonomers of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base0
7919646765RNAA type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses.1
7919646766base pairingPrinciple that bonds in DNA can form only between adenine and thymine and between guanine and cytosine2
7919646769RNA polymeraseAn enzyme that links ribonucleotides into a growing RNA chain during transcription, based on complementary binding to nucleotides on a DNA template strand3
7919646771protein synthesisForming proteins using ribosomes (RER) based on information in DNA and carried out by RNA4
7919646772polypeptideA polymer (chain) of many amino acids linked together by peptide bonds.5
7919646773amino acidsBuilding blocks of protein6
7919646774chromosomescontain genetic material and are located in the nucleus7
7919646775mRNARNA that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein; also called messenger RNA.8
7919646776tRNARNA molecules that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell9
7919646777rRNARNA molecules that, together with proteins, make up ribosomes10
7919646778adenineA double-ring nitrogenous base found in DNA and RNA. Pairs with Thymine.11
7919646779thymineA single-ring nitrogenous base found only in DNA. Pairs with Adenine.12
7919646780cytosineA single-ring nitrogenous base found in DNA and RNA. Pair with guanine13
7919646781guanineA double-ring nitrogenous base found in DNA and RNA. Binds with cytosine.14
7919646782uracila nitrogen-containing base found in RNA (but not in DNA) and derived from pyrimidine. Binds with adenine15
7919646783codonA specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid16
7919646784anticodongroup of three bases on a tRNA molecule that are complementary to an mRNA codon17
7919646785intronA segment of a gene situated between exons that is removed before translation of messenger RNA and does not function in coding for protein synthesis.18
7919646786exonA sequence within a primary transcript that remains in the RNA after RNA processing; also refers to the region of DNA from which this sequence was transcribed19
7919646787promoterA specific nucleotide sequence in the DNA of a gene that binds RNA polymerase, positioning it to start transcribing RNA at the appropriate place.20
7919646790ribosomerRNA and protein molecules that functions in protein synthesis; consists of a large and a small subunit. In eukaryotic cells, is assembled in the nucleolus21
7919646791translationThe synthesis of a polypeptide using the genetic information encoded in a mRNA molecule. There is a change of "language" from nucleotides to amino acids.22
7919646792transcriptionThe synthesis of RNA using a DNA template.23
7919646797gene mutationA change in the sequence of the bases in a gene, which changes the structure of the polypeptide that the gene codes for.24
7919646798chromosomal mutationA change in the chromosome structure, resulting defects in meiosis25
7919646799substitutionA type of point mutation; the replacement of one nucleotide and its partner in the complementary DNA strand by another pair of nucleotides.26
7919646800deletiona type of gene mutation in which a nucleotide is deleted27
7919646801insertionA mutation involving the addition of one or more nucleotides pairs to a gene.28
7919646805terminatorIn bacteria, a sequence of nucleotides in DNA that marks the end of a gene and signals RNA polymerase to release the newly made RNA molecule and detach from the DNA.29
7919646806bacteriophageA virus that infects bacteria; also called a phage.30
7919646807TATA boxA promoter DNA sequence crucial in forming the transcription initiation complex.31
7919646808Central dogma32
7919710164RNA nucleotide33
7919719200RNAiprocess in which RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules.34
7919830429poly A tailmakes mRNA more stable, prevents its degradation, allows the mRNA molecule to be exported from the nucleus and translated into a protein by ribosomes in the cytoplasm.35
7919860026GTP capused as a recognition signal for ribosomes to bind to the mRNA.36
7919887801mRNA processingAddition of cap and tail to the ends of the transcript & Removal of introns37
