During proofreading, which of the following enzymes reads the DNA?
Stells [14]

Answer:

DNA pol

Explanation:

DNA polymerases (DNA Pol) are enzymes present in both eukaryotic and prokaryotic cells. These enzymes are responsible for the synthesis of complementary DNA molecules. These enzymes are essential for DNA replication and generally work by using an individual DNA strand as a template to synthesize a complementary strand, so DNA polymerases are DNA dependent.

During the proofreading, DNA polymerase is the enzyme that has the function of reading the DNA.

How are alleles represented in genetics?
shtirl [24]
Well to start off, alleles determine genotypes. For example, an uppercase letter may be the dominant trait (A - Black hair), whereas the lowercase letter may be the recessive trait (a- Red hair). So whichever outer appearance trait is noticeable, that allele is dominant.

How are saturated fats different from unsaturated fats
ivolga24 [154]

Answer:

Saturated fats have no double bonds in their chemical structure. They are “saturated” with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature. Unsaturated fats are typically liquid at room temperature. They differ from saturated fats in that their chemical structure contains one or more double bonds. They can be further categorized as: 3  

Monounsaturated fats: This type of unsaturated fat contains only one double bond in its structure. Monounsaturated fats are typically liquid at room temperature and include canola oil and olive oil.

Polyunsaturated fats: This type of unsaturated fat contains two or more double bonds in their structure. They are liquid at room temperature. Polyunsaturated fats include safflower oil, sunflower oil, and corn oil.
