Learn about RNA and the process of Transcription

What is RNA?

• RNA is similar to DNA, except the sugar is different; ribose is used instead of deoxyribose

• RNA is only a single strand

• Uracil is used instead of Thymine

• There are three kinds of RNA

      a. mRNA

      b. rRNA

      c. tRNA

Multiple Select

How is RNA different from DNA? RNA :

• is double-stranded

• is single-stranded

• contains Uracil

• Contains Thymine

• Contains Ribose

Multiple Choice

Which of the following is NOT a type of RNA?

• pRNA

• tRNA

• rRNA

• mRNA

What is RNA used for?

• It is used to make proteins   

• The central dogma: DNA--> RNA--> Protein

• It has two stages: Transcription and Translation

Multiple Choice

What is the final step of the central dogma?

• DNA

• Protein

• RNA

• ATP

What is Transcription?

• DNA never leaves the nucleus, instead a copy called mRNA (Ribonucleic Acid) is sent out

• Remember, RNA is a single strand, it uses uracil instead of thymine and It has the sugar ribose

• The mRNA leaves the nucleus and attaches to a ribosome, or rRNA.

Multiple Choice

DNA never leaves the nucleus.

• True

• False

Multiple Choice

RNA Polymerase

• binds the two strands of DNA

• separates the DNA double helix

• Denatures the DNA

• has no effect on the DNA

Multiple Choice

The base complementary to Adenine in RNA is

• Thymine

• Guanine

• Cytosine

• Uracil

Multiple Choice

Once DNA Polymerase reaches the termination site, the DNA double helix

• breaks down and disappears

• separates

• goes back together

• does nothing

Multiple Choice

The mRNA is a

• single-strand

• double helix

• twisty-turvey molecule

• carbohydrate
