Ligases are enzymes that link two dna fragments together. Suppose a bacterium develops a mutation in the ligase gene needed for
Goryan [66]

Answer:

Cell will not replicate because of incomplete DNA replication.

Explanation:

DNA replication is crucial for reproduction/replication of any organism as it involves the duplication of genetic material. So if an organism is unable to perform proper DNA replication it would not be able to reproduce.

DNA polymerase is the enzyme that synthesize the new DNA strand in DNA replication. DNA polymerase can synthesize a strand only in 5'→3' direction. Both of the strands of DNA molecules are opposite in direction. So one strand is synthesized continuously called as leading strand while the other strand is synthesized in form of okazaki fragments called as lagging strand.

The okazaki fragments are joined together by the enzyme ligase. So if Ligase enzyme is absent in bacteria it would not be able to synthesize the lagging strand of DNA and thus could not be able to produce a replica of DNA. And if there is No replication of DNA then No replication of cell would occur.

Imagine that a clam accumulates one unit of mercury in its body from the water it lives in. How many units of mercury would a st
DochEvi [55]

Answer:

182,500 units.

Explanation:

<em>The answer would be </em><em>182,500 units of mercury.</em>

<u>Assuming there is an average of 365 days in a years, 10 years is therefore equal to:</u>

10 x 365 = 3650 days.

<u>The stingray eats 50 clams per day. Hence, the total number of clams that would have been eaten in 10 years equals:</u>

3650 x 50 = 182,500 clams

<u>Each clam accumulated 1 unit of mercury in its body from the water it lives in and there is no loss of mercury between the clam and the stingray. Hence, the total number of units of mercury the stingray would have accumulated in 10 years equals:</u>

182,500 clams x 1 unit = 182,500 units of mercury.

F the DNA is carrying a silent mutation, what will be the impact it will have on the organism
Mumz [18]

Answer:

The DNA carrying a silent mutation will have no gene expression or result on the phenotype or physical appearance of the organism. Silent mutations code for the same amino acid resulting in more genetic diversity, having a genotypic advantage, but providing no noticeable differences.
