Genetics Review #2

Front

What is cloning in genetics?

Back

Cloning is the process of creating a genetically identical copy of an organism or a cell.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of genetic mutation where a part of the DNA sequence is removed or lost.

Front

If Cytosine makes up 20% of a DNA sample, what percentage of Thymine is present?

Back

30% of the DNA sample is Thymine, based on Chargaff's rules.

Front

What is genetic engineering?

Back

Genetic engineering is the direct manipulation of an organism's genes using biotechnology.

Front

What are the main techniques used in genetic engineering?

Back

Common techniques include CRISPR, gene cloning, and recombinant DNA technology.

Front

What is the significance of Chargaff's rules in DNA structure?

Back

Chargaff's rules state that in DNA, the amount of Adenine equals Thymine and the amount of Cytosine equals Guanine.

Front

What is the role of enzymes in genetic engineering?

Back

Enzymes such as restriction enzymes and ligases are used to cut and join DNA fragments.

Front

What is the purpose of cloning in biotechnology?

Back

Cloning is used for producing genetically identical organisms for research, agriculture, and medicine.

Front

What are the ethical considerations of genetic engineering?

Back

Ethical considerations include potential risks to biodiversity, human health, and moral implications of altering life forms.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in the DNA sequence.
