Oxygen is a by-product of ______________ and is needed by living organisms for the process of ______________.

Katyanochek1 [597]

The answer is D, photosynthesis and respiration.

—Evidence—

Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.

Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration.

The y-shaped site at which a double-stranded molecule of dna is separated into two single strands for replication.

aleksandrvk [35]

The Y shaped structure with active region present is called replication fork

The separation of the 2 single strands of DNA creates a ‘Y’ form referred to as a replication ‘fork’. the 2 separated strands will act as templates for making the new strands of DNA.

LEADING STRAND

one of the strands is oriented in the 3’ to 5’ path (toward the replication fork), this is the main strand?. the other strand is oriented inside the 5’ to 3’ direction (away from the replication fork), that is the lagging strand?.

because of their extraordinary orientations, the 2 strands are replicated in a different way: A small piece of RNA called a primer (produced by means of an enzyme referred to as primase) comes along and binds to the end of the leading strand. The primer acts as the place to begin for DNA synthesis.

DNA polymerase? binds to the leading strand after which ‘walks’ alongside it, including new complementary? nucleotide? bases (A, C, G and T) to the strand of DNA within the 5’ to 3’ direction.

This form of replication is referred to as continuous

LAGGING STRAND

Several RNA primers are made by means of the primase enzyme and bind at numerous points alongside the lagging strand.

Chunks of DNA, known as Okazaki fragments, are then introduced to the lagging strand also in the five’ to a few’ path.

This sort of replication is known as discontinuous as the Okazaki fragments will want to be joined up later.

Once all the bases are matched up (A with T, C with G), an enzyme referred to as exonuclease strips away the primer(s). The gaps wherein the primer(s) were are then filled by but extra complementary nucleotides.

The brand new strand is proofread to make sure there are no errors inside the new DNA series.

eventually, an enzyme referred to as DNA ligase? seals up the sequence of DNA into two non-stop double strands.

The end result of DNA replication is two DNA molecules consisting of 1 new and one old chain of nucleotides. That is why DNA replication is described as semi-conservative, 1/2 of the chain is part of the unique DNA molecule, half is ultra-modern.

Following replication the brand new DNA routinely finishes up into a double helix.
