Answer:
Explanation:
Protein molecules binding to DNA initiate sequences of biochemical transitions that control and regulate all major process in the living cells
These protein molecules strongly bond to special sequences of DNA known as specific binding sites
Theoretically , there are two main components of binding forces
- One of them is purely electrostatic attraction between oppositely charged DNA and protein molecules that are mostly sequence independent
- Other one comes from particular DNA sequence that strengthens the attraction of protein molecules
The origin of this increased affinity is due to combination of van der waals , hydrogen , covalent and steric interactions as well as electrostatic charge patterns recognition
Some studies has suggested that there is an additional statistical interaction potential between protein and DNA molecules. Source of this interaction is due to the specific structure and symmetry of DNA sequences to which protein molecule binds
DNA sequences with repeated homogeneous segments (A:T or G:C) have stronger affinity for association to DNA binding proteins as compared to heterogeneous sequences
3 types of interactions takes place on encounter of protein and DNA molecule which are van der waals forces , hydrogen bonds between complimentary organic bases (base pairs) and hydrophobic interactions between the nitrogenous bases and the surrounding sheath of water
Of all these forces van der waals forces are strongest and hydrophobic interaction between the nitrogenous bases and surrounding sheath of water is the weakest

Answer:
El síndrome de Down es el resultado de un niño nacido con un cromosoma adicional agregado al número esperado de cromosomas (generalmente destinado a ser 46).
El síndrome de Angelman se produce cuando un niño nace con una mutación en el 15º cromosoma heredado de los padres.
Explanation:
En el síndrome de Down, se agrega un cromosoma adicional al complemento de cromosomas que un niño debe heredar de sus padres. Se supone que un niño tiene un complemento de 46 cromosomas (23 cada uno) de ambos padres. Una vez que hay un aumento en este número, se establece el síndrome de down. Es una condición cromosómica común. Puede manifestarse como una trisomía, causada por la no disyunción durante la división celular, lo que resulta en 3 copias del cromosoma 21 en lugar de 2 copias, mosaicismo, donde una mezcla de células se clasifican en 2 grupos que contienen un complemento completo de 46 cromosomas y el otro un el cromosoma adicional lo hace 47 y la translocación ocurre cuando un cromosoma 21 adicional o parte del 21 se une al cromosoma 14. Los niños generalmente tienen cabezas y orejas pequeñas, cuellos cortos, caras planas, etc.
En el síndrome de Angelman, el cerebro se ve afectado en gran medida, debido al efecto de la mutación en el sistema nervioso. La pérdida de la función en el 15º cromosoma es responsable del síndrome de Angelman, que resulta en la incapacidad del niño para hablar, mantener el equilibrio, moverse, un desarrollo deficiente tanto física como intelectualmente.
1. Only use the Bunsen burner when specifically instructed to use during an experiment authorized by the instructor.
2. Never turn on the gas unless instructed by your instructor.
3. Always light the match or lighter before turning on the gas.
4. Always inspect the Bunsen burner, tubing, and gas valve before using the burner.
5. Always follow proper procedures for lighting and using the Bunsen burner.
6. Tie back long hair and don’t wear loose long sleeve.
These are some and good luck,!
If helped.. mark as brainliest please ;)
