SCiE From DNA To Protein

The addition of a phosphate group.

(15 letters, p … n)

The statement that information flows from DNA to RNA to polypeptide.

(2 words, first letters c & d, respectively)

The synthesis of RNA, using one strand of DNA as the template.

(13 letters, t … n)

An RNA virus that contains reverse transcriptase. Its RNA serves as a template for cDNA production, and the cDNA is integrated into a chromosome of the host cell.

(10 letters, r … s)

The sequence of a protein that directs the protein through a particular cellular membrane.

(2 words, first letters s & s, respectively)

The mRNA codons that signal the end of protein translation at the ribosome: UAG, UGA, UAA.

(2 words, first letters s & c, respectively)

The synthesis of a polypeptide or protein. This occurs on ribosomes, using the information encoded in messenger RNA.

(11 letters, t … n)

A transcript of one of the strands of DNA; carries information (as a sequence of codons) for the synthesis of one or more proteins.

(3 words, first letters m, r & a, respectively)

Combination of a ribosomal light subunit, an mRNA molecule, and the tRNA charged with the first amino acid coded for by the mRNA; formed at the onset of translation.

(2 words, first letters i & c, respectively)

The region of an operon that acts as the initial binding site for RNA polymerase.

(8 letters, p … r)

The end of protein synthesis triggered by a stop codon which binds release factor that causes the polypeptide to release from the ribosome.

(11 letters, t … n)

An often single stranded nucleic acid whose nucleotides use ribose rather than deoxyribose and in which the base uracil replaces thymine found in DNA. Serves as genome from some viruses.

(2 words, first letters r & a, respectively)

A family of double stranded RNA molecules. Each kind of ... carries a specific amino acid and anticodon that will pair with the complementary codon in mRNA during translation.

(3 words, first letters t, r & a, respectively)

A pyrimidine base found in nucleotides of RNA.

(6 letters, u … l)

Three nucleotides in messenger RNA that direct the placement of a particular amino acid into a polypeptide chain.

(5 letters, c … n)

A complex of RNA and protein that recognizes both the signal sequence on a growing polypeptide and receptor protein on the surface of the ER.

(3 words, first letters s, r & p, respectively)

An enzyme that catalyzes the formation of RNA from a DNA template.

(2 words, first letters r & p, respectively)

A complex consisting of a threadlike molecule of messenger RNA and several ribosomes. The ribosomes move along the mRNA, synthesizing polypeptide chains as they proceed.

(8 letters, p … e)

The mRNA triplet (AUG) that acts as a signal for the beginning of translation at the ribosome.

(2 words, first letters s & c, respectively)
