RNA VS. DNA

The RNA made directly from the DNA is:

• tRNA
• mRNA
• rRna
• all of these

The RNA found in the ribosome is

• mRNA
• RNA
• tRNA
• rRNA

DNA contains the bases Adenine, Guanine, Cytosine and Thymine.  Which base is replaced in RNA by another base?

• Adenine is replaced by Uracil
• Thymine is replaced by Uracil
• Guanine is replaced by Uracil
• Cytosine is replaced  Uracil

During the process of ___________, the codons produced after DNA makes mRNA. 

• decoding
• translation
• transcription
• transforming

Why do cell makes ?

• RNA controls all the functions of the cells.
• The DNA must stay in the nucleus to perform its jobs.  The mechanisms outside the nucleus are set up to work with a single strand of RNA.
• Both of these are correct.
• None of these are correct.

How are DNA and RNA similiar?

• They have nucleotides.
• They have the same sugar.
• They have the same bases.
• They are double strands.

How many amino acids would be produced from the mRN CGCUAUAGC?

• 1
• 2
• 3
• 4

A series of amino acids linked together will produce a __________________.

• carbohydrate
• protein
• lipid
• sugar

• build blood and bones
• all of these

Why is it important for a single gene to be able to produce hundreds to thousands of the same RNA molecule?

• There is a low need for protein.
• There is no need for protein.
• All of these.
• Proteins must be continuously made in the cell, so the codes in the genes must be used repeatedly.
