List five ways in which scientists study and manipulate DNA?

Answer 1

1. Extract DNA from the cells

2. Cut DNA into smaller pieces.

3. Identify the sequence of bases in a DNA molecule

4. Make unlimited copies of DNA

Answer 2

DNA extraction -> cutting DNA -> separating DNA -> reading the sequence -> cutting and pasting -> making copies

This is brittany2

Scientist use their knowledge of the structure OS DNA and its chemical properties to study and change DNA molecules. Different techniques are used to extract DNA from cells, to cut DNA into smaller pieces, to identify the sequence of bases in a DNA molecule, and to make unlimited copies of DNA.

Answer 3

small pieces of DNA can be extracted from fossilized organisms

DNA fragments can be transferred between organisms

small DNA fragments can be pieced together using computers to determine the sequence of an entire gene

some animals have been cloned, creating exact copies of them

Answer 4

Scientists study and manipulate DNA through techniques such as PCR (polymerase chain reaction) to amplify DNA, gene cloning to create copies of genes, gene editing tools like CRISPR-Cas9 to make precise changes to DNA sequences, DNA sequencing to determine the order of nucleotides in a DNA molecule, and gel electrophoresis to separate DNA fragments based on size.

Answer 5

1. You must extract DNA

2. You must purify the DNA

3. You must drain the DNA

4. You must read the DNA

Answer 6

Recombination

Restriction enzymes

Polymerase chain reaction

Genetic engineering by the use of vectors

cant think of the 5th one. sorry.

Answer 7

dont know

nucletide
