a culture of e. coli is irradiated with uv light. the highest frequency of mutations would be obtained if after the irradiation,

Klio2033 [76]

Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.

UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:

A base (adenine)
T base (thymine)
G base (guanine)
C base (cytosine)

The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a thymine base. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and cause all sorts of abnormalities.

Which of the following statements correctly identifies the location of the hydrogens bonds in DNA

asambeis [7]

Answer:

This question is incomplete as it lacks options. However, it can be answered based on general knowledge of the DNA structure.

Hydrogen bonds in a DNA are located between the nucleotides that holds the double stranded DNA molecules.

Explanation:

Deoxyribonucleic acid (DNA) is the genetic material in living cells. The DNA molecule is made up of nucleotides monomers. However, since the DNA molecule is double-stranded, the nucleotides are of two chains composed of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

The two chains of nucleotides in a DNA molecule are called strands. Each strand is bonded to one another by the nucleotides using complementary base pairing i.e. A-T, G-C. The bonds between the nucleotidew of each strand is called HYDROGEN BOND.

Hence, HYDROGEN BONDS in a DNA molecule is located in between two nucleotides of each strand. That is, hydrogen bond holds Adenine to Thymine and Guanine to Cytosine.

QUESTION 4

CaHeK987 [17]

Correlational study is used to show the type of association or relationship which exists between two or more variables using statistical analysis. Ken's research shows that there is a relationship between childhood anger management and adult earning.

According to Ken's research, learning how to control anger leads to making more income during adulthood. This signifies a positive relationship between good anger management in childhood and earning made during adulthood.

Similarly poor anger management in childhood leads is associated with low earning during adulthood.

Hence, Ken's research shows that there is a relationship between childhood anger management and adult earnings.
