Combined Unit 5 Test Review

Match the following image of RNA with the correct name.

• mRNA

• 
• rRNA

• 
• tRNA

• 

The mRNA must do what in order to make a protein?

• The mRNA must be replicated before making a protein.
• The mRNA must be transcribed into DNA to make a protein.
• The mRNA must be degraded to prevent protein synthesis.
• The mRNA must join with tRNA.

Put the following characteristics in either the DNA or RNA category.

Groups:

(a) DNA

,

(b) RNA

• stores genetic information

• in nucleus and cytoplasm

• deoxyribose sugar

• ribose sugar

• transfers genetic information

• only in nucleus

• single strand

• double strand

The monomer of a DNA strand is called...

• amino acid
• sugar
• fatty acid
• nucleotide

What determines the information that the DNA holds?

• The sequence of nucleotides in the DNA.
• The type of organism it belongs to.
• The number of chromosomes in a cell.
• The age of the organism.

• lipids
• proteins
• carbohydrates

How are we able to have so many proteins with such variety of functions?

• Proteins are created from a single type of amino acid.
• All proteins have the same structure and function.
• The variety of proteins arises from the different combinations and sequences of the 20 amino acids, leading to diverse structures and functions.

• The variety of proteins is due to environmental factors only.

Translate the following mRNA strand.

GAU UUC CGA

• Gly-Leu-Ser
• Val-Ala-Gly
• Asp-Phe-Arg
• Thr-Cys-Pro

There are three steps in protein production. The first is transcription, DNA to ​ (a)   . This happens in the ​ (b)   , while translation happens in the ​ (c)   . Translation is the process of going from RNA to a ​ (d)   .

• RNA
• nucleus
• cytoplasm
• protein

Transcribe and then translate the following DNA sequence to make a protein.

CAT GTA CCG

• Ala-Gly-Ser
• Leu-Arg-Tyr
• Val-His-Pro
• Gly-Cys-Thr
