Mitochondria are cell structures that contain a small quantity of DNA.
Scientists are sequencing the DNA of one particular gene in mitochondria to
help identify different species of many animals including myriapods. The
sequences that they find are called ‘barcodes’.
(i) State the part of the cell that contains most of the DNA.
[1]
(ii) Suggest how DNA barcoding might be useful in the classification of animals,
such as myriapods.
Answers
The use of the DNA barcoding is that by comparison with a reference library such as DNA sections an individual sequence can be used to uniquely identify an organism to a species just like how a supermarket scanner uses the black stripes of the UPC barcode to identify an item

Alice and her friends looked at a bunch of ladybugs. They noticed the ladybugs had different numbers of spots. They each had different ideas about why the numbers of spots were different.
This is what they said: Which person do you agree with the most?
A) Karen: I think they must all be different species of ladybugs.
B)Troy: I think each ladybug has the same number of spots as its parents.
C)Isaac: I think it depends on the age of the ladybugs. As they get older they add more spots.
D)Fred: I think it has to do with the sex of the ladybug. Males will add more spots to compete for the females.
E) Andrea: I think it depends on what each ladybug was born with.
F) Alice: I think they change their number of spots when there is a need for them to do so.
Explain your thinking. Describe your ideas about why the ladybugs look different.
Answers
Explanation: Not all ladybugs are born with spots, the dots are a warning to predators that they are toxic. They get the spots when they need them to protect themselves.
People who have leukemia, a cancer that affects white blood cells, are often given Cytarabine. This drug inhibits the synthesis of DNA. Which phase of the cell cycle is most affected by Cytarabine?
A
Interphase
B
Cytokinesis
C
Prophase
D
Anaphase
Answers
Answer:
I think interphase because fna synthesis happens within the s-phase of the cell cylce and 5he s phase is suring interphase and not mitosis
The phase of the cell cycle which is most affected by Cytarabine is the Interphase. Thus, the correct option is A.
What is the cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The entire cell cycle can be divided into two phases.
The InterphaseThe M-phase (division phase).As per the question, the drug Cytarabine inhibits the synthesis of DNA, it definitely inhibits the interphase of the cell cycle. This is because the synthesis of DNA occurs in the S-phase of the cell cycle which is a substage of the interphase.
Therefore, the interphase of the cell cycle must be affected by the drug Cytarabine. Thus, the correct option for this question is A.

How does the attachment of spindle fibers differ between mitosis and meiosis I?
Answers
In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
WHAT IS MITOSIS AND MEIOSIS?
Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.WHAT IS SPINDLE FIBER?
Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division). During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

In the oldest fossils found in Bitter Springs (Cyanobacteria), why can we only find the remains of single celled organisms
Answers
Answer:
Due to presence at early days of the planet.
Explanation:
We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.
