10-09: DNA/RNA replication

Question 1

Eukaryotic DNA Gene Structure

DNA is broken up into regions that five rise to what?

Answer 1

Exons (coding regions for proteins)

Question 2

Eukaryotic DNA Gene Structure

What are exons separated by?

Don’t code for proteins

Answer 2

Introns

Question 3

Eukaryotic DNA Gene Structure

What is splicing?

Answer 3

Removes introns after the DNA is first copied in a linear fashion

Question 4

After modifications are made, what happens to the mature mRNA?

Answer 4

Transported out of the nucleus for translation

Translation= protein synthesis

Question 5

primary transcripts are often spliced in multiple combinations of exons

Answer 5

alternative splicing

gives rise to a family of possible proteins that can have slightly different functions,
regulation and/or tissue specificity

Question 6

A more relaxed structure and transcriptionally active

Answer 6

Euchromatin

Euch=active

Question 7

A highly condensed structure and not transcriptionally active

Answer 7

Heterochromatin

hetero=halt

Question 8

How many basepairs are in the human genome?

Answer 8

~ 3.2 billion bp

Question 9

Key term

The genetic material found in prokaryotes and eukaryotes. Double stranded polymer of deoxyribose, phosphoric acid and nitrogenous bases.

Answer 9

DNA

Question 10

Performs multiple functions inside the cell. Composed of a single stranded polymer of ribose, phosphoric acid and nitrogenous bases.

Answer 10

RNA

Question 11

Key term

Basic unit of heredity

Answer 11

Gene
