Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)

Ivenika [448]

Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.

Answer:

A Single amino acid must be polar to attract, just like water.

Explanation:

Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.

The situation that a new technology would be most likely to cause change in existing theory about cell is : D. The technology allows detection of a substance that could not be detected previously

Cell is incredibly small and we still hasn't 100% figured out their perfect mechanism yet. New technology might found the new substance that alter the cell's theory as a whole
