Question 1

What type of saccharide is the smallest carbohydrate molecule?

Accepted Answer

Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar molecule.

Question 2

The table shows the number of double bonds in three compounds with the same number of carbon atoms in the chain. ​

Which fatty acid is a saturated fatty acid?

Accepted Answer

A

Question 3

Which of the following is not a type of bond that holds the tertiary and quaternary structure of a protein together?

Accepted Answer

All the options listed (ionic bonds, disulfide bonds, hydrogen bonds, and hydrophobic interactions) play a role in maintaining the tertiary and quaternary structures of proteins.

Question 4

The table shows the number of double bonds in three compounds with the same number of carbon atoms in the chain. ​

Which fatty acid will have the lowest melting point?

Accepted Answer

The answer of The table shows the number of double...

Question 5

How many people are needed to find one person with the 10,10 pattern on TPOX and the 9,13 pattern on D16S539?

Accepted Answer

The answer of How many people are needed to find...

Question 6

Which element is not a part of a carbohydrate?

Accepted Answer

Sulfur is not a component of carbohydrates. Carbohydrates are composed of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1.

Question 7

What are the monomers that make up proteins?

Accepted Answer

Proteins are polymers made up of amino acids, which are linked together by peptide bonds to form long chains.

Question 8

Which type of lipid is made from a long-chain alcohol and a long-chain carboxylic acid?

Accepted Answer

Waxes are made from a long-chain alcohol and a long-chain carboxylic acid, forming ester bonds. They are distinct from fats and oils, which are triglycerides, and do not have the same chemical structure as waxes.

Question 9

What is the nucleotide sequence for the section of a protein consisting of His-Thr-Arg-Asp.

Accepted Answer

The answer of What is the nucleotide sequence for the...

Question 10

What is the difference between a starch and a cellulose molecule?

Accepted Answer

The primary difference between starch and cellulose molecules lies in their bonding linkages. Starch molecules have alpha linkages, which are more helical or branched, allowing them to be easily digestible by humans. Cellulose, on the other hand, has beta linkages, which are straight and form linear chains. This structural difference makes cellulose indigestible to humans, as we lack the enzyme to break down beta linkages.

Question 11

Which of the following is not an advantage for using mtDNA in forensic investigations.

Accepted Answer

The fact that mtDNA is only inherited from the maternal side is not an advantage for forensic investigations; it limits the ability to distinguish between maternal relatives, as they all share the same mtDNA profile.

Question 12

Which of the following compounds is not considered a lipid?

Accepted Answer

Hydrocarbons are not considered lipids; they are organic compounds consisting entirely of hydrogen and carbon, and do not share the same chemical properties as lipids such as oils, fats, and waxes, which are characterized by their insolubility in water and solubility in organic solvents.

Question 13

True or false: Mitochondrial DNA only comes from the mother's side of the family.

Accepted Answer

Mitochondrial DNA is inherited exclusively from the mother because the mitochondria in the sperm are typically lost during fertilization, meaning all the mitochondria (and thus mitochondrial DNA) in the embryo are derived from the egg provided by the mother.

Question 14

Which type of protein structure describes the pattern that short segments of a protein may adopt?

Accepted Answer

Secondary structure refers to the local folded structures that form within a polypeptide due to interactions between atoms of the backbone. The most common examples are alpha helices and beta sheets.

Question 15

What is the complementary strand of DNA for the given strand. A-G-T-T-C-A

Accepted Answer

The complementary strand of DNA is formed by pairing A with T and G with C. Thus, for the given strand A-G-T-T-C-A, the complementary strand is T-C-A-A-G-T.

Question 16

Which of the following is not one of the bases that can be a part of a DNA molecule?

Accepted Answer

Uracil is a nucleobase found in RNA, not DNA. In DNA, the base thymine (T) is used instead of uracil (U).

Question 17

What is the amino acid sequence of the codons?

Accepted Answer

The answer of What is the amino acid sequence of...

Question 18

What types of bonds create the distinctive shape of a pleated-sheet?

Accepted Answer

Hydrogen bonds between the backbone atoms in different polypeptide chains or between different parts of the same chain lying side by side create the distinctive shape of a pleated-sheet in proteins.

Question 19

Which of the following statements does not describe an oil?

Accepted Answer

Oils typically do not contain alcohol groups; they are characterized by being liquid at room temperature, often having lower melting points, and may contain carbon-carbon double bonds, but not alcohol groups. Alcohol groups are more characteristic of compounds classified as alcohols, not oils.

Question 20

What percent of the population has the 9,9 pattern on TPOX and the 8,14 pattern on D16S539?

Accepted Answer

The answer of What percent of the population has the...
