Restriction endonucleases typically recognize palindromic dna sequences and often generate sticky ends or single-stranded dna overhangs at cut sites - true or false?

True

Explanation:

Restriction endonucleases are enzymes that cut DNA on specific sites called restriction sites. To cut DNA, restriction endonucleases have to make  two incisions, once through each strand of the DNA double helix.

These enzymes are used in DNA cloning together with DNA ligases in order to insert genes or other pieces of DNA into plasmids.

answer: a. a gene that causes a specific trait.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
