Why is it impossible for male calico cats to exist

Answers

Answer 1

Answer:

genetics

Explanation:

calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur. Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. About one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities. XXY Syndrome renders male calicos sterile and can be the root cause of many other health problems

Explain why when the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

Answers

Answer: Each strand act as a template strand for another strand this way two strands are responsible for the production of two new strands. This way after the replication process two DNA molecules are produced.

Explanation:

S phase of the cell cycle is the synthesis phase of the cell cycle. This phase occurs after the interphase of the cell cycle. In this phase, the replication and synthesis of the DNA occur. The genetic material gets copied and doubled in this process before it enters into mitosis or meiosis. Each strand is utilized as a template strand for the synthesis of the complementary strand this way two molecules of DNA are produced. This way each cell contains a diploid set of chromosomes before it undergoes cell division into daughter cells in mitosis or meiosis.

Each strand act as a template strand for some other strand this manner strand is accountable for the manufacturing of new strands. In this manner after the replication system  DNA molecules are produced.

S phase of the cell cycle is the synthesis section of the cell cycle. This section happens after the interphase of the cell cycle. In this section, the replication and synthesis of the DNA arise. The genetic material receives copied and doubled on molecular this system earlier than it enters into mitosis or meiosis.

Each strand is applied as a  template strand for the synthesis of the complementary strand this manner molecules of DNA are produced. In this manner, every cell carries a diploid set of chromosomes earlier than it undergoes cell department into daughter cells in mitosis or meiosis.

What is the S phase?

S phase (Synthesis Phase) is the section of the cell cycle wherein DNA is replicated, taking place among the G1 phase and G2 phase. Since correct duplication of the genome is essential to a successful cellular department, the techniques that arise for the duration of the S-phase are tightly regulated and broadly conserved.

Hence it states that the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

What are minerals?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.

Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.

Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.

Explanation:

he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies

Answers

Answer:

We could feed them with another type of food free of silver salts.

Explanation:

When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.

If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

A population of African lions share the same habitat. A small group becomes reproductively isolated
from the rest of the population (mating behaviors no longer match). What type of speciation is this?
a. Allopatric speciation
b. Sympatric speciation
C. Parapatric speciation
d. Peripatric speciation

Answers

Answer:

The correct answer is - B. sympatric speciation.

Explanation:

The allopatric speciation occurs in the population that is geographically isolated, parapatric speciation takes place due to reproductive isolation however they occupy distinct nice or habitat.

Peripatric speciation is shows resemblance to allopatric speciation in terms of preventing the exchange of genes however they occur in the small peripheral population.

Sympatric produces a reproductive barrier between the small population that shows change to the parent population.

Explanation:

A negative change can result in diseases such as sickle cell anemia. This is because the amino acid that codon will code for changes.

A neutral change can result if the codon codes for the same amino acid as the original one.

A positive change can result if the new codon can express a beneficial phenotipic change. Something like having the body surviving on decreased amount of water or increased amounts of sodium is beneficial for organisms living near the equator.

Which of the following is the correct sequence of events in Protein Synthesis?
A. mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified
B. Polypeptide is formed, mRNA is processed, polypeptide chain is formed, mRNA is modified
C. mRNA strand is formed, polypeptide chain is formed, mRNA is processed, protein is modified
D. Polypeptide chain is formed, protein is modified, mRNA strand is formed, mRNA is processed

Answers

Answer: A

Explanation:

It can't be B or D because to get the polypeptide chain, we need the mNRA first to go through the ribosome. It's not C because after the mRNA is generated in the nucleus, it undergoes some modifications like splicing and the addition of the 5' cap and 3' tail.

The answer to the question is option A which is mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified.

What is Translation?

In its most basic form, expressing a gene implies producing its matching protein, and this multi-step process comprises two primary phases. The information in DNA is converted to a messenger RNA (mRNA) molecule in the first phase, which is known as transcription.

During transcription, the DNA of a gene acts as a template for complementary base pairing, and an enzyme called RNA polymerase II catalyses the creation of a pre-mRNA molecule, which is subsequently processed to form mature mRNA. The mRNA that results is a single stranded copy of the gene that must then be translated into a protein molecule.

The genetic coding is used to "read" the mRNA, which connects the DNA sequence to the amino acid sequence in proteins, during translation, the second key step in gene expression.

Each codon in mRNA is made up of three nucleotides and represents a different amino acid.

As a result, The mRNA sequence serves as a template for constructing the chain of amino acids that comprise a protein in the correct order.

So we can conclude that first mRNA strand is formed then mRNA is processed, then polypeptide chain is formed and protein is modified.
