Answer: B- Over time, beneficial variations will be passed on to future generations
Explanation:
Answer:
genetic engineering is the process of using recombinant DNA technology to alter the genetic makeup of an organism. genetic engineering involves the direct manipulation of one or more genes.
Explanation:
ggene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. genetic engineering aims to modify the genes to enhance the capabilities of the organism beyond what is normal.
Answer:
The correct answer is option B) "a deletion of two nucleotides".
Explanation:
A frameshift mutation is a type of genetic modification caused by the insertion or deletion of one or more nucleotides in a position that results in changing the sequence at which codons are translated in the ribosome. Frameshift mutations have the most serious effect on the polypeptide products since it results in changing completely the sequence of the protein. A deletion of two nucleotides after the AUG start of translation would result in a frameshift mutation, therefore this mutation would have the most serious effect on the polypeptide product.
Answer:
Options B and C
Explanation:
Living things can be divided into three domains: archaea, bacteria and eukarya
The domain "eukarya" includes kingdom fungi, plantae, and animalia
A Fungus is any member of the kingdom Fungi. Fungi are eukaryotic organisms typically having chitin cell walls but no chlorophyll or plastids. Fungi may be unicellular or multicellular. Examples of fungi are mushroom, yeast, mucor etc
Plants are multicellular eukaryotic organisms that have double-membraned chloroplasts in its cells containing chlorophyll.
Animals are multicellular organisms that is usually mobile, whose cells are not encased in a rigid cell wall (distinguishing it from plants and fungi) and which derives energy solely from the consumption of other organisms (distinguishing it from plants).
Explanation:
In biotechnology, several tools have been created to solve practical issues faced within society- one such tool is genetic engineering. Genetically modified organisms (GMs) with their DNA changed or transformed through genetic engineering methods usually GMOs include modifications in DNA through the incorporation of genes from all creatures such as plants, fungi, viruses and livestock.
These are referred to as transgenic organisms, which contribute to several innovations by increasing the nutritional value of foods and improving global food security which is the availability of food for the entire population.
- GM crops are believed to be more robust in nutritional value and taste, and may be altered to boost the nutritional profile. For example, Golden Rice,a modified staple, is thought to be the solution to preventable cases of blindness caused by vitamin A deficiency. This variety has been altered to biosynthesise β-carotene, a vitamin A precursor.
- Pest infestation leads to significant crop loss every year. These GM crops can increase food security. They are immune to pests and should decrease the use of herbicides and pesticides, thereby growing crop yields and making output more effective.
One of the first GM tomatoes dubbed the Flavr Savr was made for longer shelf life. A gene has been introduced from a different species to slow down the tomato's ripening without altering its taste or nutritional content, as well as reducing its vulnerability to fungal infection.
