Help please! DNA Assignment
vovangra [49]

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

List the three principal hormones that regulate glucose metabolism. Explain the effects these molecules have on carbohydrate met
drek231 [11]

Answer:

The three hormones are insulin, glucagon, and GIP and GLP-1.

Explanation:

After the ingestion of carbohydrates, insulin increases in the blood generating peaks in blood glucose, therefore the hormone that will increase is insulin to lower blood glucose, promoting the entry of this monosaccharide into the cells.

Different from the moments when the person enters into physical activity, and blood glucose is low, therefore glucagon is activated and seeks to remove the energy reserves from the interior of the cell.

Examples of ovoviviparous animal
stiv31 [10]

Answer:

sharks, rays, snakes, fishes, and insects

Explanation:

These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.

Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).
