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

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.

3)befor meiosis in interphase
in bacterial cells dividing cell into two control the number of chromosomes in cell in if binary fission takes long time the chromosome of bacteria will replicate again and cell will contain 3 chromosomes from main chromosome but in eukaryotic cell there is inhibition after dna replication that avoid cell to do that

What types of sensors are present within the muscle to identify how much force is generated?
xxTIMURxx [149]

The proprioceptors

The proprioceptors such as muscle spindle and golgi tendon organ are sensors located in the limbs. The proprioceptors give information about muscle length, muscle tension and joint angle which is coordinated to provide information about the limb’s position in space.

Jerimiah is studying Wave A and Wave B. Wave A is traveling at 3 hertz, and Wave B is traveling at 1.2 hertz.
svp [43]
<h2>Answer:</h2>

Correct answer is C

c. The resulting wave would travel at 4.2 hertz.

<h2>Explanation:</h2>

In this case constructive interference will occur and it will sum up or add both waves together. So that the resulting wave will travel at speed of 4.2 hertz. So, the correct option is C.
