E. Coli dna polymerase i possesses which activities?

Explanation:

There are total five DNA polymerases  found in E. coli.

DNA Polymerase I enzyme :

1. DNA Polymerase I possesses a 3´-5´ exonuclease activity also known as "proofreading" activity, which remove incorrectly paired bases which are  mistakenly paired during DNA replication by DNA pol III.

2. DNA Polymerase I also contains a 5´- 3´ exonuclease activity, which enables it to replace mismatched nucleotides in the growing strand of DNA.

4. It also removes primers from the lagging strand and finally these okazaki fragments are joined by  ligase enzyme.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
