1. Unlike DNA, RNA contains
deoxyribose
a double strand
phosphates
uracil
Nucleic acid structure
2. In transcription, uracil will bond with:
thymine
cytosine
adenine
guanine
Transcription
3. The first team of scientist to document the structure of DNA was:
Franklin and Wilkins
Watson and Crick
Pauling and Chargoff
None of the above
DNA structure
4. Organelles that synthesize protein are:
lysosomes
ribosomes
endoplasmic reticulum
golgi bodies
5. Most of the time in a cell's life, it's DNA is in the form of:
Chromatin
Chromatids
Replicated chromosomes
Spindle fibers
6. Uracil is a nitrogen base that pairs with adenine. Using this information, one could conclude that uracil is a:
Purine
Pyrimidine
Neither a purine or pyrimidine
Not enough information
7. a nucleotide does not consist of a:
polymerase
5-carbon sugar
phosphate group
nitrogen base
8. The genetic code in DNA of an individual depends on the sequence (order) of:
nucleotides
purines only
phosphates
sugars
9. Before a cell divides, it must duplicate its DNA in a process known as:
translation
transformation
transcription
replication
10. The basic unit (building block) of a protein is a (an):
carbohydrate
amino acid
lipid
hydrogen bond
11. Unlike DNA, RNA contains:
deoxyribose
a double strand
phosphates
uracil
12. The structure of DNA was first documented in:
1945
1953
1956
1962
13. In DNA replication, the new molecules produced are:
of unequal length
both assembled in the same direction
built with purines as the backbone
assembled in opposite directions
DNA replication
14. The "backbone" of DNA is composed of:
ribose and phosphates
deoxyribose and phosphates
ribose and uracil
deoxyribose and thymine
DNA structure
15. RNA differs from DNA in which of the following ways?
RNA is single-stranded
RNA contains ribose
RNA does not contain thymine
All of the above
DNA structure
16. Which of the following is NOT required for the transcription process itself?
