If a father has A blood type and a mother has B blood type, can they have a child with O blood type?

Answers

Answer 1

Answer: For example, if an O gene is paired with an A gene, the blood type will be A.

Answer 2

Answer: Yes possibly. You can even make a plummet square.

Compare and contrast the structure and function of a compound light microscope and a scanning electron microscope. Be sure to discuss the structure and function of each as well as the function and usefulness of each when examining a specimen. (5 points)

Answers

Both the compound light microscope and the scanning electron microscope are devices used for visualizing structures too small to see them with the eye. But, they differ in many ways. Some of them are:

* → The light microscope is compact, handy, and simple to use.
→ The electron microscope is large, complicated, and requires technical skills.

* → The light microscope can be used for observation of both live and dead specimens.
→ The electron microscope can be used for observation of only dead specimens.

* → The light microscope uses light rays for illumination of the specimens.
  → The electron microscope uses electron beams to view specimens.

* → The light microscope has a magnification of up to 1,500 times.
  → The electron microscope has a magnification of up to 1,000,000 times.

* → The light microscope has lenses made of glass.
  → The electron microscope has lenses made of electromagnets.

Animal cells and plant cells both contain cell membranes that surround the outside of the cell.

The cell wall solely controls what enters and leaves the cell.
B. The cell wall provides structure for the plant, which allows it to grow up and out to absorb sunlight.
C. The cell wall is flexible and controls what enters and leaves the cell.
D. The cell wall is rigid and firm, limiting the cell shape.

Which one of the following statements MOST accurately describes methylation? Methyl groups are most often added to cytosines adjacent to guanine bases in or near the promoter sequence, increasing the probability of gene expression. Methyl groups are most often added to adenine-thymine base pairs because they are held by only two hydrogen bonds, and this increases the probability of gene expression. Methyl groups are most often added to cytosines adjacent to guanine bases in or near the promoter sequence, decreasing the probability of gene expression. Methyl groups are most often added to guanine-cytosine base pairs because they are held by three hydrogen bonds, and this decreases the probability of gene expression. Methyl groups are added to most bases in the promoter region of a specific gene so that RNA polymerase and its associated proteins will bind more efficiently.

Answers

DNA methylation regulates gene expression by either luring proteins implicated in gene repression or by obstructing the DNA-binding activity of transcription factor(s). Thus, option C is correct.

What is the main role of methylation in gene expression?

A dynamic process involving both de novo DNA methylation and demethylation causes the pattern of DNA methylation in the genome to alter during development.

Every single cell in the human body undergoes billions of times of methylation, an essential biochemical process. It performs a wide range of biological processes, including detoxification. Expression of DNA.

Therefore, Methyl groups are most often added to guanine-cytosine base pairs because they are held by three hydrogen bonds, and this decreases the probability of gene expression
