What is the best source of nuclear DNA when working with hair samples?
tino4ka555 [31]
The answer is a hair root.

Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, d<span>ead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.</span>

4. Which of the following statements best describes how the traits of an organism are determined
butalik [34]

Answer Choices:

DNA provides the energy needed for an organism to grow and function

DNA is copied into mRNA, which controls cellular functions

DNA codes for proteins, which allow an organism to grow and function

DNA unzips and each strand codes for a different amino acid

Answer:

DNA codes for proteins, which allow an organism to grow and function

Explanation:

DNA provides the energy needed for an organism to grow and function  - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.

DNA is copied into mRNA, which controls cellular functions  - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.

DNA codes for proteins, which allow an organism to grow and function  - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>

DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid
