Gen

The video tutorial explains how a fragment of DNA encodes the production of specific proteins and how genes are defined by their location on a chromosome. It highlights that while some genes can determine characteristics like eye color entirely, most traits result from the interaction of multiple genes.

What is a gene primarily responsible for?

• Determining the entire DNA structure

• Encoding a specific protein

• Creating new cells

• Producing energy for the cell

How is a gene defined in terms of its physical location?

• By its position on a chromosome

• By its size

• By its color

• By its function

In rare cases, what can a single gene determine?

• The lifespan of an organism

• A specific characteristic like eye color

• The number of chromosomes

• The entire genetic makeup

What is the usual process for the production of characteristics?

• By random mutation

• By the collaboration of many genes

• By environmental factors alone

• Through the action of a single gene

Which of the following is NOT true about gene collaboration?

• It involves multiple genes

• It is responsible for most characteristics

• It is a rare occurrence

• It can involve complex interactions
