Multiple Choice

Where does transcription take place?

• nucleus

• cytoplasm

• ribosome

Explanation Slide...

Transcription takes place in the nucleus, where the DNA is transcribed into RNA before it is sent to the cytoplasm for translation.

Multiple Choice

What is occurring in this picture?

• Translation

• Replication

• Translocation

• Transcription

Explanation Slide...

The correct answer is Transcription, which is the process of creating an RNA copy of a segment of DNA.

Multiple Choice

What does mRNA do?

• provides information from DNA to ribosomes

• transfers amino acids to the ribosomes

• makes up ribosomes

• builds proteins

Explanation Slide...

mRNA provides information from DNA to ribosomes, which is its primary function in protein synthesis.

Which of the following best describes a mutagen?

• Direct manipulation of an organism's genes using biotechnology.

• Any organism whose genetic material has been altered using genetic engineering techniques.

• An agent which can change the structure of DNA, causing a mutation.

Multiple Select

The three types of mutagens are:

• Radiation (physical)

• Chemical

• Infectious Agents (biological)

• Smoke

• GMOs

Multiple Choice

What do we call the science of using the genetic makeup living things to create products?

Poll

My understanding of the learning goal: I can understand and explain that every organism requires a set of instructions that specifies its traits, and that this hereditary information(DNA) contains genes located in the chromosomes of each cell, and that heredity is the passage of these instructions from one generation to the another.
