They are both always kept in the nucleus to keep them safe from damage.

b
They are both double stranded and must be unzipped during replication and transcription.

c
They both contain the entire genetic sequence of the original DNA from their parent cell.

d
They both copy genetic code by forming a complementary sequence of nucleotides with an existing strand of DNA.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
