QUIZ Genetics Midpoint Assessment

What would you need to include in a model showing the STRUCTURE & FUNCTION of dystrophin?

• the molecular structure of the dystrophin protein

• how and where the dystrophin molecule attaches to muscle

• a side by side view comparing a large healthy muscle and small muscle with DMD

• all of these should be included

We know that our bodies need protein to repair our muscles when they have been damaged from exercise. We can get protein from the foods we eat. Why do individuals with DMD still suffer from the breakdown of their muscles even if they consume the same foods we consume?

• creatine kinase leaks out of the muscle fibers due to constant tearing as muscles contract

• too much calcium gets in, binds to protease and attacks good proteins

• tears in the muscle fibers fill with fat and scar tissue

• all of these.

Translation is the process where

• mRNA is created in the Nucleus
• mRNA is decoded to form a protein 
• glucose molecules are made
• is where lipids are synthesised

Based on what we have learned so far, we know that our muscle cells consist of a variety of important proteins. Actin and myosin are contractile proteins that cause skeletal muscles to move during contraction. Dystrophin and titin are structural proteins that provide support for the muscle cell during contraction. What determines a protein's structure and function?

• the location of the protein within the cell

• the amino acid sequence that makes up the protein

• the type of muscle: Smooth, cardiac or skeletal

• the stage of protein synthesis/gene expression

What is the location in the cell for transcription?

• nucleus
• cytoplasm
• ribosome
• mitochondria

What process is going on in this photo? 

• Transcription 
• Translation 
• Replication 
• All the above 

Which student has the most accurate cause-effect chain model based on what we know so far?

• Student A

• Student B

• Student C

• None of these

What process is happening in the diagram?

• transcription

• translation

• dna replication

• mitosis

The process to go from DNA to mRNA is _______

• translation
• transcription
• replication

Dystrophin is an important structural protein found in muscle cells that prevents tears in the membrane during muscle contraction. Proteins are made up of a strand of complex molecules, made during the process of translation. What are these individual molecules (monomers) called?

• chromosomes

• genes

• amino acids

• alleles
