Genomes and Evolution

Question 1

Genomics is the study of 4 things…

Answer 1

1. Gene sequences
2. Mechanisms of gene activity
3. Study between genetic and non-genetic factors
4. Comparisons of different species

Question 2

Whats a genome?

Answer 2

The organisms entire DNA sequence

Question 3

What is the C value paradox?

Answer 3

When more DNA does not mean a more complex organism

Question 4

There is NO relationship between

Answer 4

Genome size and organism complexity

Question 5

What does homologous mean?

Answer 5

Genes that are related through evolution

Question 6

What are gene families that are commonly found in Eukaryotes?

Answer 6

Genes that come from a common ancestor but have time to diverge from each other after duplication occurred

Question 7

What are orthologs?

Answer 7

Homologous genes that are found in 2 different species that evolved from a common ancestor

Question 8

What are paralogs?

Answer 8

Two genes within a single organism that are homologous and arose from a duplication in the past

Question 9

True or False: Sometimes the new copies of a gene evolve new functions

Answer 9

True

Ex: When human angionin diverged from (ribonuclease)

Question 10

What are unique sequences?

Answer 10

Found only once in the genome
