What is genetic engineering?
Genetic engineering is the process of cutting DNA into fragments and inserting the fragments with a desired DNA into another organism.
The organism can be of same species or different species.
It is also called genetic modification.
This process is the direct manipulation of an organism’s genome using biotechnology
It is the artificial manipulation, modification, and recombination of DNA.
The aim of genetic engineering is to produce organisms that have new or improved traits or characteristics.
By isolating and copying the genetic material of interest using molecular cloning method, a new DNA may be inserted in the host genome
For example, genetic engineering can be used to create crops that are resistant to pests and diseases.

Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .
Most of the mass of an atom is concentrated at the center of the nucleus.
Atoms are made up of three subatomic particles called
1. Protons
2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
Atom is a basic unit of matter have proton and neutron containing nucleus at the center and surrounding electrons.
What do you mean by atom ?
Atoms are the smallest and basic units of matter.
A negatively charged electron which surround the nucleus of the atom moving around the orbitals or energy levels.

what statement about the elongation of the lagging strand is correct?
A. it only occurs in prokaryotes
B. it requires multiple RNA primers to completely replicate
C. It is synthesized in the 3'-5' direction
D. it requires one RNA primer to completely replicate
E. in synthesized continously
Answers
The correct statement about the elongation of the lagging strand is D. It requires one RNA primer to completely replicate.
During DNA replication, the lagging strand is synthesized in short fragments known as Okazaki fragments. The process of lagging strand synthesis requires the synthesis of RNA primers to initiate each Okazaki fragment. These RNA primers provide a starting point for DNA polymerase to begin synthesizing the DNA fragment.
Each Okazaki fragment on the lagging strand requires a separate RNA primer for initiation. Once the RNA primer is synthesized, DNA polymerase extends the fragment by adding complementary nucleotides in the 5'-3' direction. This process continues until the entire lagging strand is replicated.
While the leading strand is synthesized continuously in the 5'-3' direction, the lagging strand is synthesized discontinuously in short segments due to its orientation relative to the replication fork. These segments are later joined together by an enzyme called DNA ligase to form a continuous and complete lagging strand.
Therefore, the statement that best describes the elongation of the lagging strand is that it requires one RNA primer to completely replicate. Multiple RNA primers are necessary to initiate the synthesis of individual Okazaki fragments, which are then joined together during the process of DNA replication.

The sexually reproducing corn has kernels that are either purple or yellow, and smooth or wrinkled. Which of Mendel's laws does the farmer's corn best support?
Answers
Due to the fact that each trait's genes are inherited individually, the law of independent assortment is the best to support the farmer's corn.
What is the law of independent assortment?The development of reproductive cells causes various genes to separately separate from one another, according to the Principle of Independent Assortment.
During his research on the genetics of pea plants in 1865, Gregor Mendel made the first observation of an independent assortment of genes and their related phenotypes.
Therefore, different qualities are inherited independently of one another, according to the Law of Independent Assortment.

What happens to the protein that results from a gene that has a gain of function mutation?
a. Makes a non-functional protein
b. Turns it into a cancer-causing protein
c. Makes a protein that is over-expressed in amount, expressed in a new location, or is always functional
d. B and C
Answers
Both the cancer-causing potential (B) and the changes in protein expression and functionality (C) are possible outcomes of a gene with a gain of function mutation. Option (d) B and C
When a gene undergoes a gain of function mutation, the resulting protein can have two main effects. First, the protein may acquire a new function or become overactive, leading to abnormal cellular processes. This can include the protein becoming cancer-causing (oncogenic) and promoting uncontrolled cell growth and division.
Second, the mutation can also lead to changes in the expression or behavior of the protein. The protein may be overexpressed in terms of quantity, meaning it is produced in larger amounts than normal. It can also be expressed in a new location within the cell or even in different cell types or tissues where it is not usually found. Additionally, the gain of function mutation can render the protein constitutively active, meaning it is always functional, even when it shouldn't be.

What human activities could impact biodiversity
Ecology question
Answers
Human activities have a significant impact on biodiversity. The term biodiversity refers to the number of different species of plants and animals in an ecosystem. Many human activities are responsible for biodiversity loss, including deforestation, pollution, and climate change.
The following are some of the human activities that could impact biodiversity:
Deforestation: Deforestation is one of the leading causes of biodiversity loss. It occurs when forests are cleared for agriculture, logging, and human settlement. When forests are cleared, many species of plants and animals lose their natural habitat. This can result in the extinction of many species.
Pollution: Pollution is another major cause of biodiversity loss. Pollution can come from many sources, including factories, vehicles, and agriculture. It can have a direct impact on plants and animals, killing them or causing them to become sick. It can also indirectly impact biodiversity by altering the environment, making it less suitable for certain species.
Climate change: Climate change is one of the most significant threats to biodiversity. As the climate changes, many species of plants and animals may not be able to adapt quickly enough to survive. This could result in the extinction of many species.
Other human activities that could impact biodiversity include overfishing, hunting and poaching, and the introduction of non-native species. To protect biodiversity, it is essential to take steps to reduce the impact of these human activities. This can include reducing carbon emissions to slow down climate change, protecting natural habitats, and reducing pollution levels.
