2. Nucleotides are composed of - ANSWER-Sugar, phosphate and a base
3. An example of a nucleic acid is - ANSWER-DNA
4. DNA differs from RNA because - ANSWER-RNA is only one linear chain,
whereas DNA consists of two chains bonded together
5. Ribosomes are necessary for - ANSWER-protein production
6. proteins are made - ANSWER-by the ribosomes
7. what is a chromosome? - ANSWER-a large, tightly bound piece of DNA
and protein found in the nucleus of cells
8. what is a genome - ANSWER-the complete set of genetic material
encoded within the DNA of an organism
9. What is the significance of the '23rd pair' of chromosomes in humans?
- ANSWER-it determines a person's sex
10. a boy's Y chromosome will generally NOT be identical to that of
his - ANSWER-great-grandfather on mother's side of family
, 11. DNA is a type of molecule called a ______. Its smaller parts are
called ________. - ANSWER-deoxyribonucleic acid; nucleotides
12. which of the following base pairs would be found in normal DNA?
- ANSWER-A and T
13. DNA is called a double helix because - ANSWER-two DNA strands
twist together
14. DNA can be visualized as a ladder. Which parts would be the
rungs (where you step) and which would be the stringers (the sides
where you hold on)? - ANSWER-The base are rungs, and the phosphate
bases are stringers
15. What are nucleotides - ANSWER-molecules that make up the
information contained in DNA
16. How is the structure of DNA molecule arranged? - ANSWER-Each
nucleotides' phosphate group binds to the sugar group of the next
nucleotide
17. What is the 'double helix' when reffering to the structure of DNA?
- ANSWER-two strands of linked nucleotides that are twisted around
each other
18. What is the correct pattern of nucleotide base pairing? -
ANSWER-adenine-thymine; guanine-cytosine
19. What is the complementary base-pairing rule? - ANSWER-adenine
will always pair with thymine, and cytosine will always pair with
guanine
