Sensory information

The somatosensory cortex is a structure located in the middle of the brain on both the right and left hemispheres. The somatosensory cortex is responsible for processing information we receive from all our senses, including:

1. Visual information- what we see
2. Auditory information- what we hear
3. Kinaesthetic information- what we can touch or feel
4. Olfactory information- what we can smell 
5. Information from our taste buds

Nitric oxide (no) participates in a signal transduction pathway that promotes relaxation of smooth muscle cells lining blood ves
timurjin [86]

Nitric oxide accomplishes this by elevating cGMP levels.

  • NO is a distinctive message. It is a gas, although it does dissolve in an aqueous solution.
  • It is a free radical with an unshared electron, which will react with thiol groups on proteins to form new complexes.
  • Unlike other second messengers, NO doesn't need energy to move inside and outside of cells. It can go where it wants, but it does not travel far because it is a reactive free radical.
  • NO acts within the cell that produces it as a second messenger. It operates as a paracrine molecule able to travel 10–20 cell diameters to affect the biology in surrounding cells. It can form complexes with proteins like hemoglobin, glutathione, and other proteins and then separate from those complexes.

Therefore, increasing cGMP levels is necessary.

Describe how you think a child’s DNA is different from his or her mother’s DNA and father’s DNA.
monitta

Answer:

  • For starters, you inherit two copies of each chromosome—one copy from your mom and one copy from your dad. <u>This means that your genome (all of your DNA) is already different because it contains chromosomes from both of your parents</u>.

  • So yes, it is definitely possible for two siblings to get pretty different ancestry results from a DNA test. Even when they share the same parents. DNA isn't passed down from generation to generation in a single block. Not every child gets the same <u>50</u>% of mom's DNA and <u>50</u>% of dad's DNA.

  • DNA is passed down to the next generation in big chunks called chromosomes. Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around <u>a 1 in 8 chance</u> that you would get no DNA from a great, great, great grandparent.

  • Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your <u>mother.19DNA</u> is the material that carries all the information about how a living thing will look and function. For instance, DNA in humans determines such things as what color the eyes are and how the lungs work. Each piece of information is carried on a different section of the DNA. These sections are called genes.

  • Each son receives DNA for his Y chromosome from his father. This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs. It has been estimated that a mutation occurs about once every <u>500</u> generations, or every <u>15,000</u> years, give or take a few millennia.

  • DNA Paternity tests can falsely exclude someone who is truly the child's biological father for a variety of reasons. One major reason is simple human error.

  • While women do inherit <u>50</u>% of their DNA from each parent, men inherit about <u>51</u>% from their mother and only <u>49</u>% from their father.

<h2>1986</h2>
  • In <u>1986</u> was when DNA was first used in a criminal investigation by Dr. Jeffreys. <u>1986</u>. The investigation used genetic fingerprinting in a case of two rapes and murders that had happened in <u>1983 and 1986.</u>

How is an RNA molecule different from a DNA molecule?
andreev551 [17]

Answer:

RNA is single-stranded and composed of nitrogenous bases, a phosphate group, and pentose sugar.

Explanation:

RNA is different from DNA because instead of having two matching bases; it is only made of one strand of nitrogenous bases. These bases are attached to the phosphate, which holds the whole strand of RNA together. The sugar acts as a carrier for the bases. The sugar in RNA is known as ribose and contains 5 carbon molecules. This is why it is called pentose sugar.
