Bju Biology Chapter 8 Basic Genetics

Which base is found in RNA but not in DNA?

• adenine

• uracil

• cytosine

• guanine

As part of its structure, a known gene contains the base sequence AATCGA.  An alteration of the sequence to AACCGA is known as

• deletion
• disjunction
• mutation
• segregation

This is the process of using a DNA template to make a strand of mRNA

• Translation
• Transcription
• Replication
• Mitosis

The main difference between the four nucleotides that make up DNA is that they have different

• sugars.
• uracil.
• bonds.
• bases.

During transcription, what does messenger RNA do?

• It delivers DNA's instructions for making proteins.
• It constructs proteins out of random amino acids.
• It strings together two complementary DNA strands.
• It strings together two complementary RNA strands.

Biologists have learned that genetic information flows from

• RNA to DNA to polysaccharides.

• DNA to RNA to proteins.

• RNA to DNA to proteins.

• DNA to polysaccharides to RNA.

What holds base pairs together?

• hydrogen bonds
• sugar-phosphate backbones
• pairs of double-ringed nucleotides
• nitrogen-carbon bonds

One difference between DNA and RNA is that....

• Only RNA has the base URACIL
• only RNA contains the base THYMINE
• only RNA contains the base CYTOSINE
