Question

the name of the enzyme that copies dna into mrna?
○ a. helicase
○ b. ligase
○ c. rna polymerase
○ d. amylase
○ e. dna polymerase
value: 10
the start codon for all proteins is ___.
○ a. aaa
○ b. aug
○ c. gaa
○ d. uga
○ e. uaa
value: 10
coping dna to mrna is called ____.
○ a. transcription
○ b. translation
○ c. transformation
○ d. transfection

Explanation:

1. The enzyme that copies DNA into mRNA is RNA polymerase. Helicase unwinds DNA, ligase joins DNA fragments, amylase breaks down starch, and DNA polymerase synthesizes DNA.
2. The start - codon for all proteins is AUG, which codes for methionine.
3. Copying DNA to mRNA is called transcription. Translation is the process of making proteins from mRNA, transformation is the uptake of foreign DNA by a cell, and transfection is the introduction of nucleic acids into eukaryotic cells.

Answer:

1. c. RNA Polymerase
2. b. AUG
3. a. Transcription
