Answer:

An important term in genetics that was not used by Mendel was the word "gene", a particle of the chromosome responsible for the traits of a living being. The molecule discovered by Oswald Avery - related to genes and inheritance - was DNA, a discovery he made in 1944.

Explanation:

Despite being considered the father of genetics and providing important information about the inheritance of traits, Mendel did not go so far as to use the term "gene," which is where the alleles responsible for those traits reside. The term "gene" was first used by another botanist, Wilhelm Johanssen, who in 1909 proposed the use of the word gene as the name of the particle responsible for inheritance.

In 1944, the Canadian physician Oswald Avery, faced with the mistaken belief that genes were found in proteins, proposed an experiment where he discovered that the molecule responsible for heredity was deoxyribonucleic acid, or DNA.

Answer:

DNA and RNA

Explanation:

The difference between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nigtrogenous bases that make up another section of the molecules. These two molecules are Ribonucleic acid and Deoxyribonucleic acid.

Ribonucleic acid contains Ribose sugar while Deoxyribonucleic acid contains Deoxyribose sugar which is the major difference between the two molecules.

What role does gene expression play in determining traits on an offspring? Explain your response

Answers

genes correspond to one or more DNA sequences that carry the coding information required to produce a specific protein, and that protein in turn carries out a particular function within the cell.

Gene expression has been defined as the process where the genes produce proteins and RNA. They determine the traits in offspring as various types of proteins pass from parent to offspring.

What is gene expression?

Gene expressions are said to be the expression of the genome products in the cell that undergoes the process of transcription and translation to produce the RNA and protein structures that are responsible for providing the phenotype and genotype.

The genes code for the RNA and protein that regulates the amount and type of proteins to be expressed in the offspring that are passed from a parent through reproduction methods. They are hereditary patterns that vary in some amount to make two individuals different from each other.

Therefore, gene expression plays an important role in determining the trait in offspring.

Explanation:

La miopia es un caracter bastante comun en la especie humana. Un matrimonio en el que ambos conyugues poseen vision normal, tienen dos hijos, uni con una vision normal y el otro con miopia. Teniendi en cuenta el fenotipo de todos los miembros de la familia ¿quenpodrias deducir del gen que controla la miopia? ¿ que genotipo podrias asignsr a cada individuo?

Answers

Answer:

El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa  miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm   Tendrían otro hijo homocigota recesivo con miopia, mm.

Explanation:

Datos disponibles:

Ambos padres poseen visión normalUno de los hijos tiene visión normalEl otro hijo tiene miopia

Podríamos establecer que M es el alelo dominante, mientras que m es el alelo recesivo.

A partir de la información brindada, podríamos suponer que:

Opción 1:

La miopia es un caracter expresado por un gen dominante. Si este fuera el caso, entonces al menos uno de los padres debería tener miopia para poder heredarle al hijo el alelo dominante para expresar el caracter. Si este fuera el caso, los posibles genotipos de los padres serían:

Parental)  Mm   x   mm (al menos uno de los padres con miopia)

F1) 1/2 Mm (Hijo miope)

    1/2 mm (Hijo con visión normal)

Pero en este caso, los dos padres tienen visión normal, entonces si el gen dominante expresa la miopia, los genotipos de los padres serian homocigotas recesivos, mm. Si ambos padres son homocigotas recesivos, no podrían heredarle a ningun hijo el alelo de la miopia. En este caso, la cruza sería:

Parental) mm    x    mm

F1) 100% mm (todos los hijos con visión normal)

Sin embargo, para el ejemplo planteado, los dos padres tienen visión normal, uno de los hijos tiene visión normal y el otro tiene miopia, lo que nos conduce a la segunda opción.

Opción 2:

La miopia es un caracter heredado por un gen recesivo, m. Mientras que la visión normal es heredada por un gen dominante, M. Entonces, si este fuera el caso, para que ambos padres con visión normal, tengan un hijo homocigota recesivo para el caracter, entonces ambos padres deberian ser heterocigotos. Su hijo miope heredaría un alelo recesivo de cada padre y expresaría el defecto. El genotipo de las personas con miopía sería entonces homocigota recesivo. Esta cruza sería de la siguiente manera:

Parental) Mm    x    Mm  (Ambos padres heterocigotas)

Gametos) M   m     M     m

Cuadro de Punnet)

                M             m

     M       MM         Mm

     m       Mm         mm

F1) 3/4 o 75% de probabilidad de tener un hijo con visión normal

    1/4 o 25% de probabilidades de tener un hijo miope.

Entonces, podemos concluir que:

El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa  miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm   Tendrían otro hijo homocigota recesivo con miopia, mm.

Vision problems. Heart attack. Stroke.

Explanation:

Answer:

Many things.

Explanation:

Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.

Too high BP(hypertension):

If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.

Too low BP(hypotension):

If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

If a strand of DNA has 45% A, what percent will be C?

Answers

Answer:

55%

Explanation:

Answer:

[tex]\boxed {\boxed {\sf C=5\%}}[/tex]

Explanation:

There is a method to calculating base percentages known as Chargaff's Rule. It states:

[tex]A+T+G+C=100\%[/tex]

We know the DNA has 45% Adenine or A.

Adenine always pairs equally with Thymine. In other words, the percentage of adenine equals the percentage of thymine (45% Thymine or T).

[tex]45\%+45\%+C+G=100\%[/tex]

[tex]90\%+C+G=100\%[/tex]

Subtract 90% from both sides.

[tex]90\%-90\%+C+G=100\%-90\%[/tex]

[tex]C+G=10\%[/tex]

Cytosine(C) and Guanine(G) pair equally and their percentages will be equal. We can divide 10% by 2.

[tex]C+G=10\% /2[/tex]

[tex]C/G=5\%[/tex]

The percentage of Cytosine or C is 5 percent.
