Answer:

The principal enzyme involved in DNA replication is called _DNA polymerase_. The enzyme joins _nucleotides_ to synthesize a new __complementary_ strand of DNA. DNA replication is called __semiconservative__ because each new DNA molecule is made up of one original and one new strand.

Explanation:

DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.

The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.

DNA strands are antiparallel, and replication occurs only in 5´-3´direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

Chloroplast

DNA

Answers

Answer:

DNA

Explanation:

Answer:

Explanation:

Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.

El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.

Put the following layers of the digestive tract wall in order from the lumen to the deepest layer: 1. lamina propria 4. digestive (mucous) epithelium 2. muscularis externa 5. serosa 3. submucosa 6. muscularis mucosae

Answers

Answer:

4. digestive (mucous) epithelium

1. lamina propria

6. muscularis mucosae

3. submucosa

2. muscularis externa

5. serosa

Explanation:

The first layer of the digestive tract, starting from the lumen, is the epithelium. This has different characteristics depending on the digestive tract section. Then there is a loose connective tissue called lamina propria. Next, there is a layer of muscle called muscularis mucosae. It is only present in the digestive mucosae. The next layer is the submucosa, which has dense connective tissue and the submucosal plexus. Then it follows the muscular externa, which has muscle, and it is in all the digestive tract except for the esophagus and stomach. Lastly, we have the serosa layer.

¿De qué maneras son los espermatozoides diferentes a todas las otras células del cuerpo masculino?

Answers

Answer:

Los gametocitos masculinos, o espermatozoides, difieren de las células del cuerpo porque pueden entrar en meiosis y crear espermatozoides. En el ciclo de meiosis I, un espermatocito primario diploide ubicado en los túbulos seminiferosos de los testículos se divide en dos espermatocitos secundarios haploides. Las dos células se convierten en cuatro espermatozoides a través de la meiosis II.

Discuss 3 different types of mutations that can happen

Answers

Answer:

Explanation:

Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.

there are 3 types of mutations, base substitutions - single base mutations are called point mutations. Point mutations are the most common type of mutation and there are two other types. point mutations occur in DNA sequence seconding proteins are either silent, missense or nonsense. Deletions is the second type of mutation, this results when one or more base pairs are lost from the DNA. If one or two based are deleted the translation frame is altered resulting in a garbled message and nonfunctional product. A deletion of three or more bases leave the reading frame intact. A deletion of one or more corona result in a protein missing or more amino acids. this may be deletions or not. And lastly insertions this is when you have additional base pairs which may lead to frameshifts depending on whether or not multiples or three base pairs are inserted. combinations of insertions and deletions leading to a variety of outcomes are also possible.

Possible variations of a gene that controls a specific trait

A) Heredity

B) Phenotype

C) Gene

D) Allele

Answers

Answer:

D

Explanation:

Alleles are the different possibilities for the trait (brown, blue, green.)

Possible variations of a gene that controls a specific trait are referred to as alleles. Therefore, the correct option is D.

Alleles are different types or forms of a gene that reside at the same locus on a certain chromosome. They contribute to the wide variety of traits seen within populations and can exist in several forms, such as dominant or recessive.

For example, there may be alleles for blue eyes, brown eyes, or green eyes, for a gene that affects eye color. Different alleles play a role in the variety of phenotypes (observable characteristics) that people can display.

Therefore, the correct option is D.
