A common type of DNA damage from UV light results in:

Biology
1 answer:
Yakvenalex [24]3 years ago
3 0

Answer:

C

Explanation:

The damage to DNA usually occurs where there  are two consecutive thymine nucleotides on  a DNA strand. The energy from the UV light causes the two dimers to form a cyclobutane pyrimidine structure.  Proofreading and repair mechanism of DNA find it difficult to repair this kind of damage on DNA. During replication, therefore, DNA polymerase is unable to replicate this region hence leading to a mutation on the replicated strand at this local point.

Tomtit [17]

Answer:

a. Only the DNA of β cells contains the gene for insulin; only the DNA of chief cells contains the gene for pepsinogen

Explanation:

As stated in the question above, insulin production is exclusive to β cells in the pancreas. This is because only these cells have a gene that manages the production and excretion of insulin within an organism. Similarly, only the main cells of the stomach have the capacity to produce pepsinogen, which indicates that the gene responsible for managing this production is unique to these cells.

arsen [322]

Answer:

The correct answer is C.

Explanation:

The amount of genetic variation in two humans is 0.1 percent of their genome. Human genetic variation refers to the biological difference that exists in the human population.

The genetic variation in humans and apes genome is about 4 percent which is 35 million differences in a single nucleotide.

The genetic variation between apes and humans (Homo sapiens), according to scientists includes gene expression differences, variation in the transportable elements and type and number of repetitive genomic DNA transportable elements, the difference in the gene sequence, single nucleotide polymorphic, etc.

According to research, 97 percent of humans and orangutans genomes are identical. Based on evolution, among all apes, the orangutans are very special as it has been stable for the past 15 million years.

Therefore, is the genetic variation between humans and orangutans is the greatest.

The nurse should include in their discharge notes to the couple the different ways they may access to guarantee birth control.
They may continue to use barrier methods which are the most safe when it comes to not disturbing any hormonal balance or intervening with the milk. Condoms for men are usually the most easily accessed to.
Besides the barrier methods, there are also the hormonal methods. When breastfeeding these are not the most used methods. There is a special pill, progestin-only pill, that is the most appropriate because it doesn't affect milk supply when taken after 6 to 8 weeks after the birth. All hormonal methods should be taken always when counselled with the doctors.
