- Company Profile:
A preexisting polynucleotide chain in DNA replication to which new nucleotides can be added.
Industry:Archaeology
A primary transcript of a tRNA gene whose bases must be extensively modified and that must be processed to remove extra RNA sequences in order to produce the mature tRNA molecule. In some cases, the primary transcript may contain the sequences of two or more tRNA molecules.
Industry:Archaeology
A primary transcript of adjacent rRNA genes (16S,23S, and 5S rRNA genes in prokaryotes; 18S, 5.8S, and 28S rRNA genes in eukaryotes) plus flanking and spacer DNA that must be processed to release the mature rRNA molecules.
Industry:Archaeology
A process whereby an intervening sequence between two coding sequences in an RNA molecule is excised and the coding sequences ligated (spliced) together.
Industry:Archaeology
A sex chromosome present in two copies in the homozygous sex and in one copy on the heterozygous sex.
Industry:Archaeology
A sex chromosome that when present is found in one copy in the heterogametic sex, along with an X chromosome, and is not present in the homogametic sex. Not all organisms with sex chromosomes have a Y chromosome.
Industry:Archaeology
A single mRNA transcript in prokaryotic operons of two or more adjacent structural genes that specifies the amino acid sequences of the corresponding polypeptides.
Industry:Archaeology
A staining technique in which metaphase chromosomes are stained with quinacrine mustard to produce temporary fluorescent Q bands on the chromosomes.
