Question 12 of 24

1

In eukaryotic chromosomes, replication can be initiated at several different points whilst in prokaryotes the entire genome is replicated at once.

Select one of the following:

True
False

Explanation

Question 13 of 24

1

Fill the blank spaces to complete the text.

At the leading strand, DNA splits the into its two anti- strands, creating a replication .

Explanation

Question 14 of 24

1

Genetic information is copied from ❌ because ❌ is too large to leave the nucleus, but ❌ can. Therefore ❌ is temporarily unzipped by ❌ and is used as a ❌ to assemble complementary nucleotides into ❌. The ❌ then goes through the pores of the ❌ into the cytoplasm to attach to a ❌. This process is called transcription.
