1. Which of the following are components of a DNA nucleotide?Phosphate group, nitrogenous base, deoxyribose sugar
2. Complementary base pairing is key to the genetic code. In a DNA
molecule, the nitrogenous base cytosine pairs with _____ guanine
3. The complex formed by DNA wrapped around histone proteins is
called chromatin
4. What is the role of DNA polymerase in DNA replication? It
“proof-reads” new daughter strands to be sure the bases are in the
correct order; it synthesizes a daughter strand that is
complementary to the template strand
5. The code for storing genetic information in DNA is based on the
sequence of ______ in the DNA molecule. Nucleotides
6. Dna is a molecule found in the nucleus of ___ cells Eukaryotic
7. In living organisms, information for making protein flows from
Dna to rna to protein
8. Which nucleic acid is usually composed of two strands of
nucleotides? DNA
9. In the ladder analogy, which of the following form the sides of the
ladder? deoxyribose sugar, phosphate groups
10. DNA polymerase ____ preserves genetic continuity from
parents to offspring
11. In living organisms, which nucleic acid functions as the
genetic material? DNA
, 12. In the genetic code, an amino acid is encoded by_____ three
nucleotides
13. The new strand of nucleotides formed during replication is
called the _____ daughter strand
14. In addition to linking together nucleotides to synthesize a
daughter strand, DNA polymerase also _____ "proofreads" the
order of nucleotides
15. What is the sequence that matches a replication of this DNA
sequence? ATTGCTGGACTGATC TAACGACCTGACTAG
16. The process of forming mRNA from the template strand of
DNA is called _____ transcription
17. RNA polymerase is a(n) ________ enzyme
18. Transcribe the following coding DNA sequence below into a
complementary sequence of mRNA: TAGCTGCCAGTAGCA
AUCGACGGUCAUCGU
19. The base sequence on a template strand of DNA is
ATGCCGTAC. Which of the following represents a
complementary mRNA? UACGGCAUG
20. A triplet of nucleotides in tRNA is called a(n) ___________
anti-codon
21. Translate the following mRNA sequence into the right amino
acid sequence AUG-GUU-UGC-AGC-GGA-UAG Place these in
the proper order Met-VAL-CYS-SER-GLY-STOP
