Transcription DOL

A diagram of the steps in the production of a protein is shown. Which description identifies the purpose of Step A in this process?

• to correct the mutations in the DNA sequence

• to produce an exact copy of the DNA molecule

• to copy the DNA of a gene sequence onto a strand of mRNA

• to assist in the folding of the protein

Students are modeling mRNA during the process of protein synthesis. The mRNA strand will be​ (a)   the DNA template strand; however​ (b)   instead of ​ (c)   will be paired with adenine.

• complementary to
• uracil
• thymine
• an exact copy of
• adenine
• cytosine
• guanine

What differentiates DNA and RNA? Select ALL that apply.

• The sugar in DNA is deoxyribose, the sugar in RNA is ribose

• DNA is single-stranded, RNA is double-stranded

• DNA stays in the nucleus, RNA can leave the nucleus

• DNA stays in the ribosome, RNA is found in the Golgi Apparatus

• DNA uses thymine, RNA uses uracil

The initial steps in gene expression are modeled in the diagram. Double-stranded DNA first unwinds into two strands. Diagram 2 shows the process of ​​ (a)   . The product of Diagram 2 is ​ (b)   .

• transcription
• translation
• replication
• recombination
• mRNA
• protein
• tRNA
• polymerase

What would be the product of transcription if the sequence of DNA reads:

C G T G G A T A

What enzyme is responsible for building the complementary mRNA strand in transcription, using the original DNA strand as a template?

• helicase

• ligase

• RNA polymerase

• DNA polymerase
