Column B
a.a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA.
b.a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
c.a compound found in living tissue as a constituent base of RNA. In DNA its place is taken by thymine.
d.the form of RNA in which genetic information transcribed from DNA as a sequence of bases is transferred to a ribosome
e.any part of a gene that will encode a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing
f.a compound which is one of the four constituent bases of nucleic acids. A pyrimidine derivative, it is paired with adenine in double-stranded DNA.
g.an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
h.A noncoding, intervening sequence of DNA within a gene that is transcribed into mRNA but is removed from the primary gene transcript and rapidly degraded during maturation of the RNA
i.a sugar of the pentose class which occurs widely in nature as a constituent of nucleosides and several vitamins and enzymes.
j.molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA
