* Nucleotide and Genetic Information Quiz

What are the three parts that make up a nucleotide?

• Nitrogenous base, deoxyribose, phosphate group

• Ribose, adenine, cytosine

• Thymine, guanine, uracil

• Phosphate, ribose, uracil

What are Chargaff’s rules for nucleotide bonding?

• Adenine can only bind with cytosine

• Cytosine can only bind with guanine

• Thymine can only bind with guanine

• Adenine can only bind with uracil

What are the differences between DNA and RNA?

• DNA is single stranded, RNA is double stranded

• DNA contains uracil, RNA contains thymine

• DNA has deoxyribose, RNA has ribose

• DNA is made of proteins, RNA is made of lipids

What does the order of bases in our DNA code for?

• Assembling lipids

• Assembling proteins

• Assembling carbohydrates

• Assembling nucleotides

How can a mutation during replication affect a protein that is synthesized?

• Mutations can stop protein synthesis entirely or change the amino acids incorporated

• Mutations always enhance protein function

• Mutations have no effect on protein synthesis

• Mutations only occur in non-coding regions

What is the central dogma in biology?

• The theory stating the flow of information in cells

• The process of cell division

• The structure of DNA

• The function of enzymes

Protein synthesis is an important process for living organisms because:

• Proteins make up the traits of all living organisms

• Proteins are not essential for life

• Proteins only function in energy storage

• Proteins are only found in plants

What are the events of transcription?

• DNA gets copied into mRNA; this happens in the nucleus

• DNA is translated into proteins

• RNA is converted into DNA

• Proteins are synthesized directly from DNA

What is the difference between an intron and an exon?

• Introns are the RNA that is not needed and exons are the mRNA that is expressed

• Introns are expressed and exons are removed

• Both introns and exons are expressed

• Introns are only found in prokaryotes

What are the events of translation?

• Translation is the process of mRNA converting to protein; this happens in the ribosomes

• Translation occurs in the nucleus

• Translation involves DNA replication

• Translation is the process of protein degradation
