Answer:

The options

A. It suggested that DNA is the

"transforming principle."

B. It confirmed that DNA is a double helix composed of two antiparallel strands.

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.

D. It proved that DNA is

semiconservative replication.

The CORRECT ANSWER IS A.

A. It suggested that DNA is the

"transforming principle."

Explanation:

A. It suggested that DNA is the

"transforming principle."✔

Griffith's experiments proved

that transformation can be seen in

pneumococcus, but gave no proof based on what molecular background the transformation was

WHILE, the Avery MacLeod-McCarty experiments proved that DNA was THE TRANSFORMING PRINCIPLE.

B. It confirmed that DNA is a double helix composed of two antiparallel strands.❌

These findings were established by James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.❌

The findings was established by Erwin Chargaff.

D. It proved that DNA is semiconservative replication.❌

The findings was established by Matt Meselson and Franklin Stahl.

Answer:

DNA Replication:

Replicate the following strand of DNA:

Original DNA: A T G A A C CA T T C A G T A T G G

Complementary DNA:

Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:

A T G A A C C A T T C A G T A T G G

Then the compliment is (replace with the opposite base pairs):

T A C T T G G T A A G T C A T A C C

Transcription:

Transcribe the DNA to make an mRNA molecule

COMPLIMENTARY DNA:

mRNA Molecule:

So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:

A U G A A C C A U U C A G U A U G G  

Translation:

Translate the mRNA into the corresponding amino acids.

mRNA MOLECULE:

AMINO ACID:

Using the DNA sequence provided, determine the amino acids.

Next, take each codon (3-base set) to the table and record the corresponding protein:

A U G = Methionine (start)

A A C = Asparagine

C A U = Histidine

U C A = Serine

G U A = Valine

U G G = Tryptophan

ORIGINAL DNA: A T G G G T C T A G C G A A A G A T

Complementary DNA:

mRNA DNA Molecule:

Amino Acid:

And we do it all again:

A T G G G T C T A G C G A A A G A T = original DNA

T A C C C A G A T C G C T T T C T A = complementry DNA

A U G G G U C U A G C G A A A G A U = mRNA

A U G = Methionine (start)

G G U = Glysine

C U A = Leucine

G C G = Alanine

A A A = Lysine

G A U = Aspartate

The body can be invaded by pathogens , which are harmful microorganisms that cause infection diseases. The body then initiates a
pochemuha

Answer:The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
