Why are single-stranded binding proteins necessary for DNA replication?
Margarita [4]

Answer:

d.They prevent the two parental strands from coming together again.

Explanation:

During the process of DNA replication, the two DNA strands should be separated from each other to serve as a template. To separate the two DNA strands, the helicase enzyme breaks down the hydrogen bonds between the complementary base pairs of the DNA strands. The process uses ATP as a source of energy.

Due to the presence of complementary base pairs, the separated DNA strands have a tendency to reanneal by the formation of hydrogen bonds. To prevent the reannealing of separated DNA strands, single stranded binding proteins bind to them. Binding to single stranded binding proteins to the separated DNA strands does not allow them to reanneal.

wariber [46]

Answer:

False

Explanation:

Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.  Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites.  Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.
