Question

the steps of transcription are as follows:
①. a specific section of dna
exposing a set of bases
②. along one strand of dna (called the \template\ strand, complementary rna bases are brought in.

• the enzyme involved is
• in rna, uracil binds to the adenine on dna
• as in dna, cytosine binds to guanine.
• the other strand of the dna molecule (the \sense\ strand), isnt read in eukaryotic cells.

③. adjacent rna nucleotides form

• the rna strand is
• the dna molecule
• rna can then leave the nucleus through the nuclear pore and go into the
• this process occurs in the nucleus (and, in particular, dark coloured spots in the nucleus called

(singular = nucleolus)

• there are 3 types of rna, each with different functions.

Explanation:

• For the first blank in step ①: DNA unwinds during transcription to expose bases.
• For the enzyme in step ②: RNA polymerase is the enzyme that brings in complementary RNA bases.
• For step ③:
• Adjacent RNA nucleotides form phosphodiester bonds.
• The RNA strand is transcribed (synthesized) from DNA.
• The DNA molecule rewinds (re - anneals).
• RNA goes into the cytoplasm.
• The process occurs in nucleoli (plural of nucleolus).

Answer:

① unwinds
② RNA polymerase
③ phosphodiester; transcribed (or synthesized); rewinds (or re - anneals); cytoplasm; nucleoli
