Ch 2.4 Genomes

Question 1

Protein and dna interactions

Answer 1

• need temporary interact to replicate ( enzymes )
• diff proteins interact in diff regions dna based on side chains
  ( possible h-bond pd-pd interactions)
• diff interactions with A-T and C-G
• Can interact with sides chains and base pairs

Question 2

Genome:

Answer 2

All of the genetic material that’s passed onto offspring

Question 3

Genotype:

Answer 3

Genetic make up of cells

Question 4

Phenotype:

Answer 4

Observable characteristics

Question 5

Gene

Answer 5

Small part of the genome

Question 6

What’s the correlation between genome size, number of genes and complexity of life?

Why?

Answer 6

None

• genomes have both coding and non-coding genes

Question 7

Transcriptime:

Answer 7

Genes actively being transcribed to mRNA

subset all genes in genome

Question 8

Dna packaging in bac

Answer 8

Has core, protein around the core, supercoiled dna around it

Question 9

Dna packaging in Eu

6

Answer 9

1) dna duplex
2) nucleosome fiber ( wrapped around histone proteins )
3) chromatin fiber
4) coiled chromatin fiber
5) coiled coil
6) metaphase chromatid ( chromosome)
