Chromosomes, Genes, and DNA

"Review Activity - DNA Structure" - Label the parts of the strand of DNA.

WARM UP

Gene Expression: the process by which a gene gets turned on in a cell to make RNA and proteins. ​

The process by which a gene gets turned on in a cell to make RNA and proteins. 

Environmental Factors that Affect:

• Temperature

  • Himalayan Rabbits: temperature affects fur pigment

• pH

• nutrition

Gene Expression

​Genotype: specific combo of alleles for a given gene

Phenotype: physical manifestation of the organism's genotype

Multiple Choice

A particular mouse found in northern Canada has a light gray coat in the colder winter months but in the summer months has a dark brown coat. What can you say about this change?

• This is an example of natural selection

• The dominant gene switches generations.

• The gene's expression is controlled by temperature

• The gene's expression is controlled by light exposure

Multiple Choice

DNA and RNA are both nucleic acids. What are some differences between DNA and RNA?

Select TWO correct answers.

• DNA is double-stranded and RNA is single-stranded

• DNA contains all of your genetic information, and RNA contains none

• RNA is a much more complex molecule than DNA

• DNA is much more complex in structure and function than RNA

• RNA contains more different types of nucleotides than DNA
