CFA #2 RNA & Protein Synthesis (12.1 & 12.2)

Identify the different types of RNA.

Groups:

(a) mRNA

,

(b) tRNA

,

(c) rRNA

• Carries copies of the instructions for assembling proteins

• Carries amino acids and matches them to the coded message for assembling proteins.

• Makes up the subunits of ribosomes.

In which ways is RNA different from DNA?

Groups:

(a) RNA

,

(b) DNA

• contains thymine

• contains the sugar deoxyribose

• contains the sugar ribose

• generally single-stranded

• contains uracil

The "language" of RNA is called the ________________, and it uses three-letter "words" called (polypeptides/amino acids/codons/nucleotides).

• nucleotide strategy
• transcription strategy
• substitution mutation
• genetic code

The "language" of RNA is called the (nucleotide strategy/transcription strategy/substitution mutation/genetic code), and it uses three-letter "words" called ________________.

• polypeptides
• amino acids
• codons
• nucleotides

A sequence of amino acids called a ____________ is produced during the process of (transcription/intron removal/translation/replication). During this process, the (anticodon/glucose/intron/exon) of a tRNA molecule binds to a codon of mRNA.

• DNA Polymerase
• DNA Transcriptase
• carbohydrate
• polypeptide

Carlita was hired today for a job as a laboratory assistant. She will work for a professor of molecular biology who wants to make new discoveries about genes, DNA, RNA, and their functions. Carlita's work will MOST LIKELY contribute to which of these specific research goals?

• Identifying the molecule that makes up genes
• Describing the role of RNA polymerase in RNA synthesis
• Determining the links between genes and the traits they influence
• Identifying the types of nucleotides that make up RNA
