4 0

Answer: (1) It has a tail to travel to the egg (2) contains a nucleus in the head which will fertilise the egg

Explanation: Firstly it has a tail to help it travel to the egg. Secondly it contains the nucleus in the head that will fertilise the egg. Thirdly the acrosome contains enzymes in order for the sperm to penetrate the egg. Finally, the sperm cell is packed with mitochondria to provide the energy needed to reach the egg.

One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. What is this type of chromosom
Aleks04 [339]

One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. What is this type of chromosomal alteration called <u>translocation.</u>

A chromosomal fragment is translocated when it is moved from one genomic sequence to another. Around two nonhomologous chromosomes, a translocation mechanism takes place in order to permit the interchange of fragments created by chromosomal breakage.

When a segment of one chromosome separates and affixes towards another chromosome, translocation takes place. If there is neither genetic material growth nor loss in the cell, such a form of rearrangement would be referred to as balanced.

Why can't both strands of DNA be replicated at the same time?
saw5 [17]

Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.

DNA Replication:

<u>Step one: </u>

DNA Helicase (unzips) separates the strands.

<u>Step two:</u>

DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.

<u>Step three:</u>

DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.

  • The leading strand is made continuously.
  • The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.

<u>Step four:</u>

Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.

<u>Step five:</u>

Another DNA Polymerase fills in the gaps that are left behind with DNA.

<u>Step six:</u>

DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.

<u>Final answer:</u>

DNA Replication cannot replicate at the same time due to the leading and lagging strand.

Good luck!
