Answer:
Non-coding DNA.
Explanation:
Inversion is a type of chromosomal abnormality in which the sequence of a segment of a chromosome is inverted or rotated at an angle of 180 degrees. This type of abnormality can change the reading frame of the gene and can cause mutations.
But if the genome sequence is non-coding that is not involved in the formation of protein synthesis than even if the reading frame is inverted will not affect the phenotype of the cell. Also, the non-coding sequences are removed by the splicing mechanisms.
Thus, Non-coding DNA is correct.
Answer:
Explanation:
We are asked to find how much of a 40 gram sample remains after 12 years.
Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed.
- 12 years/3 years = 4 half-lives
Every time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample.
- 1 half- life: 40 g / 2 = 20 g
- 2 half-lives: 20 g / 2= 10 g
- 3 half-lives: 10 g / 2 = 5 g
- 4 half-lives: 5 g / 2 = 2.5 g
There is also a formula that can be used to solve this problem.
Where A₀ is the initial amount, t is the time, and hl is the half-life.
We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife.
After 12 years, <u>2.5 grams </u> of Iron-55 will remain.
Answer:
