Lesson 14.1: RNA

RNA is

• a type of protein

• a type of nucleic acid

• a type of carbohydrate

• a type of lipid

Match the following.

• Transfer RNA

• transport amino acids to the ribosome

• Ribosomal RNA

• carry genetic information from DNA to the ribosome

• Messenger RNA

• synthesize proteins directly

Transcription is the process of:

• copying DNA into RNA

• translating RNA into protein

• replicating DNA

• synthesizing lipids

RNA polymerase is an enzyme that is responsible for what function?

• Transcription of DNA into RNA

• Replication of DNA

• Translation of RNA into protein

• Degradation of RNA

The role of a promoter in transcription is to:

• initiate the process of transcription by providing a binding site for RNA polymerase

• terminate the transcription process

• translate mRNA into protein

• replicate DNA

The role of RNA in genetics according to the passage is:

• To store genetic information

• To catalyze biochemical reactions

• To transfer genetic information

• To replicate DNA

Categorize the following.

Groups:

(a) DNA

,

(b) RNA

,

(c) Both

• Contains a phosphate

• Made of nucleotides

• Single stranded

• Contains uracil

• Contains sugar deoxyribose

• Contains a 5 carbon sugar

• Double stranded

• Type of nucleic acid

• Contains sugar ribose

• Contains adenine, cytosine, guanine

• Contains thymine

In RNA, adenine pairs with which nitrogenous base?

• uracil

• cytosine

• guanine

• thymine
