What type of sugar does DNA have?

Deoxyribose

Why does DNA need to replicate?

To pass complete sets of DNA to the daughter cell.

100

What base does RNA have that DNA does not?

Uracil (U)

100

Where does transcription take place?

Nucleus

200

This physician extracted a substance from the pus of his patients, he runs tests on the substance.

Friedrich Meischer

200

What are the building blocks of DNA?

Nucleotides

200

During replication, which enzyme unzips the DNA?

Helicase

200

What are the three types of RNA? Include their name and abbreviation.

Messenger- mRNA

Ribosomal- rRNA

Transfer- tRNA

200

What is the final product of translation?

Protein strand

300

English chemist creates the famous "image 51" by shooting x rays through DNA crystals. 

Rosalind Franklin

300

What is the shape of DNA?

Double helix

300

What is the enzyme responsible for building the complementary strand?

DNA polymerase

300

What type of sugar does RNA contain?

Ribose

300

How is the genetic code read in the ribosome during protein synthesis?

3 letters at a time, called a codon

400

When was the structure of DNA discovered?

1953

400

These two things alternate to make up the backbone of DNA and RNA

Phosphate and Sugar

400

Why are single stranded binding proteins placed on the DNA strands during replication?

To avoid tangling/recoiling of the DNA

400

What does tRNA have to ensure it gets the correct amino acid?

Anti-codon

400

What is the final produce of transcription?

Copied mRNA strand

500

This scientist identified the structure of individual DNA bases

Phoebus Levene

500

Nitrogenous bases can be classified into two groups- based on shape/number of rings.

Purines and Pyrimidines

500

List the steps of DNA replication- include the enzymes at play

DNA uncoils, helicase unzips, primase places primers, DNA polymerase builds the complementary strand, ligase glues the okazaki fragments, the two DNA strands will recoil, each having one half from the original

500

Compare and contrast DNA and RNA. Create a venn diagram. (2 things in each column for credit)

DNA: double stranded, in nucleus, deoxyribose, thymine

RNA: single stranded, freely moves in cell, ribose, uracil

Both: made of nucleotides, has A,G,C , sugar/phosphate backbone

500

What are the steps in protein synthesis, starting with DNA to protein.

DNA is copies by mRNA, then taken to the ribosome, ribosome reads the code 3 letters at a time, tRNA brings coded amino acids to the ribosome, they attach with peptide bonds, then when STOP is signaled the strand is done.
