Across
In bacteria, the 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.
A specific nucleotide sequence in the DNA of a gene that binds RNA polymerase, positioning it to start transcribing RNA at the appropriate place.
An enzyme that links ribonucleotides into a growing RNA chain during transcription, based on complementary binding to nucleotides on a DNA template strand.
The prcess by which information encoded in DNA directs the synthesis of of prteins or, in some cases, RNA's that not translated into proteins and instead function as RNA's.
An initial RNA transcript from any gene; also called pre-mRNA when transcribed from a protein-coding gene.
A genetic information system in which a series of three-nucleotide-words spicifies a sequence of amino acids for a protein ( a polypeptide chain).
Nontemplate strand the has the same sequence as the mRNA strand except it has Thymine (T) instead of of Uracil (U).
The synthesis of a polypeptide using the genetic information coded in an mRNA molecule. There is a change of language from nucleotides to amino acids.
Down
Messenger RNA- synthesized using a DNA template, that attaches to ribosomes in the cytoplasm and specifies the primary structure of protein. (In Eukaryotic cells-pre-RNA has to go through processing before becoming mRNA))
In transcription, the nucleotide position on the promoter where RNA polymerase begins synthesis of RNA.
A region of DNA that is transcribed into an RNA molecule.
A complex of rRNA and protein molecules that function as a site of protein synthesis in the cytoplasm;consists of a small and large subunit. In eukaryotic cells, each subunit is assembled in the nucleolous
The DNA strand that provides the pattern, or template, for ordering, byby complementary base pairing, the sequence of nucleotides in an RNA transcript.
On an mRNA, the triplet grouping of ribonucleotides used the translation machinery during polypeptide synthesis.
The synthesis of RNA using a DNA template
Triplets of nucleotides.
