1. What does DNA stand for?

Deoxyribonucleic acid

2. How many chromosomes does a human have?

46 chromosomes 3. What is the structure of DNA?

A molecule of DNA consists of two strands that form a double helix structure

4. What is the shorthand for ribonucleic acid?

RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis

5. What three things make up DNA?

These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases

6. DNA is arranged in a

DNA bases pair up with each other, A with T and C with G, to form units called base pairs.

7. Nitrogen bases are held together by what type of bond?

The nitrogen bases are held together by hydrogen bonds: adenine and thymine form

two hydrogen bonds; cytosine and guanine form three hydrogen bonds.

8. How many base pairs in a human? 3 billion

9. Given, AGGTCCG what is the corresponding base sequence?

UAGGCUAA

10. What are the three major differences between RNA and DNA?

● RNA is single-stranded while DNA is double-stranded. ● RNA contains uracil while DNA contains thymine. ● RNA has the sugar ribose while DNA has the sugar deoxyribose.

11. Why could Rosalind Franklin not win a Nobel Prize?

he had died of ovarian cancer four years earlier and the Nobel committee does not consider posthumous candidacies.

12. What’s the job of Helicase?

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes.

13. What does DNA polymerase need before it can begin its job? What creates this structure?

DNA polymerase

14. What makes the lagging strand different from the leading strand?

Within each fork, one DNA strand, called the leading strand, is replicated continuously in the same direction as the moving fork

15. What is the job of DNA ligase?

DNA ligases play an essential role in maintaining genomic integrity by joining breaks in the phosphodiester backbone of DNA that occur during replication and recombination....
