Engage week 9 revision

Proteins are made up of...

• Amino Acids

• Nucleotides

• Monosaccharides

• Fatty acids/glycerol

What is not a property of lipids?

• Stores carbon for energy

• Hydrophobic

• Hydrophilic

• Made up of carbons and hydrogens

Structures such as alpha helices and beta pleated sheets are a part of the ______ structure of a protein

• Primary

• Secondary

• Tertiary

• Quaternary

Answer explanation

Primary structure - amino acid sequence

Secondary structure - common patterns (alpha helixes, beta sheets)

Tertiary structure - complete 3D shape

Quaternary structure - more than one amino acid chain

PCR stands for...

• Proteinase Chain Reaction

• Polymerase Copying Rapidly

• Polymer Copy Reaction

• Polymerase Chain Reaction

What don't you need for PCR?

• DNA/RNA template and Primers

• Enzyme and co-factors

• Free-floating DNA bases (dNTPs)

• SDS-PAGE

Using the mean, standard deviation, median, and interquartile range is a type of ______ statistics?

• Demographic

• Descriptive

• Diverging

• Documentitive

Which two of these are independent variables?

• How many hours studied

• Number of patients used in the study

• Dose of coffee administered

• Test scores

Answer explanation

Independent variable - the variable that is stable, and manipulated throughout the experiment (e.g. coffee dose, number of hours studied)

Dependent variable - the variable that depends on (changes because of) the independent variable

(e.g. test scores)

• mRNA, protein

• DNA, mRNA

Select correct one

• Genetic code is only present in rats.

• 4 bases are used in different combinations to make codons.

• Genetic code is adequately punctuated.

• Uracil is not a part of mRNA.
