Question: Which two statements are true for the leading strand in DNA?
It is synthesized toward the replication fork.
It is synthesized in the 3′ to 5′ direction.
It is synthesized away from the replication fork.
It is synthesized in the 5′ to 3′ direction.
Answer:
The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"
Explanation:
Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.
Answer:
6 and 6
Explanation:
All elements have an equal number of protons and neutrons
The given statement is False.
The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.
The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.
The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
Answer:
The answer is most likely the 3rd option.
