According to the base-pairing rules for DNA, which of the following statements
NOT true?
A always pairs with T
C always pairs with G
T always pairs with G
T always pairs with A
Answer:
T always pairs with A
Explanation:
I think so I'm super sorry if its wrong :)
According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.
What is base-pairing in DNA?Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.
Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs
Although they keep the two strands of DNA together, they are not strong enough to withstand replication.
Therefore, the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, hence option C is correct.

List the cell organelles involved in energy generation for the cell.
Answer:
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
Crossing over occurs during meiosis and leads to changes in the chromosomes. What type of chromosomes does crossing over produce?
1. Chromosomes containing DNA from two different parental chromosomes
2. Chromosomes identical in genetic makeup to the parental chromosomes
3. Chromosomes containing more genes with non recombinant chromosomes
4. Chromosomes carrying genes from one parent
Answer:
1.
Explanation:
because the DNA is being mixed up while crossing over
Crossing over occurs during meiosis and leads to chromosomes containing DNA from two different parental chromosomes, hence option 1 is correct.
What is meiosis?New allelic combinations are created in the daughter cells as a result of the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis.
Homologous chromosomes couple along their lengths during meiosis, one from each parent. At locations known as chiasma, the chromosomes overlap.
The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
Therefore, the genetic complement in each daughter cell at the end of meiosis is best described as a haploid set of chromosomes resulting from chromosomal recombination between the parents.

Which evolutionary mechanism increases inheritable variations
Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift
Answer:
Recombination Of Genes
Explanation:
Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.
What are genetic variations in a population?Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.
Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.
Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.
Therefore, option A is correct.

En un cruce entre peces naranjas y peces grises se obtiene una generación (f1) de 50% peces grises . Realice el cruce y explique lo ocurrido dato: el color naranja es dominante sobre el color gris
Answer:
Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).
Explanation:
Datos disponibles:
Cruce entre peces naranjas y peces grises50% de la F1 son peces grisesNaranja dominante sobre grisPodemos nombrar el alelo dominante para color naranja N, y al alelo recesivo para color gris n.
Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.
Supongamos que uno de los parentales lleva el genotipo Nn, y el otro parental es nn.
Cruce:
Parental) Nn x nn
Gametas) N n n n
Fenotipos) Naranja Gris
Cuadro de Punnett) N n
n Nn nn
n Nn nn
F1) 2/4 = 1/2 = 50% de la progenie tendrá genotipo heterocigoto, Nn
2/4 = 1/2 = 50% de la progenie tendrá genotipo homocigota recesivo,

So Belinda did a lot of research in the library and come upon the idea that
eating carrots will make turtles go faster. She decided to test her ten turtles.
She fed five turtles their normal turtle food. She fed the other five carrots. All
the turtles got their normal sleep and water requirements. Then, after a week
