In pea plants, T is the allele for tall plants, while t is the allele for dwarf plants. If you have a tall plant, demonstrate wi

Answer:

Explanation:since T- represent tallness

t-dwarf plant

TT- means the plant is homozygous tall i.e the allele T is the same 100% talk

Tt- means the plant is heterozygote tall which implied that though this plant express tallness its still have gene for shortness hidden in its cell and if crossed with a plant that is dwarf some of the offspring will be dwarf.

From the test cross all the gametes are heterozyote - Tt Tt Tt Tt

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>
  • The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
  • Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).
  • It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
  • The AVP gene for it is found on human chromosome 20.
  • Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
  • It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
  • Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.

What is the new peptide chain when the new dna segment is translated for 3'- TACAGGGTGCTACCCACT-5'
kakasveta [241]

Answer:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

Explanation:

Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.

In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the

mRNA sequence from this DNA during transcription will be:

AUG UCC CAC GAU GGG UGA

From this mRNA sequence, the peptide chain that will result following translation is:

Methionine- Serine- Histidine- Aspartate- Glycine- stop
