Explanation on Mitosis

Kipish [7]

Mitosis is the division that results in two “daughter” cells. Both of these daughter cells have the same number of chromosomes as the “parent” cell.
Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
Prophase: the DNA is copied and the chromosomes pair up
Metaphase: the chromosomes line up in the middle of the cell
Anaphase: sister chromatids are pulled apart from each other towards opposite sides of the cell
Telophase: the cell begins to pinch in the middle and separates into two identical daughter cells

How did the frameshift change the amino acids?<br> Please it’s due today

notka56 [123]

A single insertion or deletion of a nucleotide will basically lead to a frameshift mutation where the “reading frame” is disrupted. Normally, amino acids are encoded by three nucleotides, called a codon.

ATP stands for Adenosine Triphosphate. The bond between the __________ (first, second, or third) phosphate group and the _______

polet [3.4K]

Answer:

The bond between the _second_________ phosphate group and the third__phosphate group is a high energy bond.

Explanation:

Adenosine triphosphate is a nucleotide with three phosphate groups. The second and third phosphate groups are bonded by high energy covalent bonds to the rest of the ATP molecule, which consists of a sugar, which is ribose, the first phosphate group, and the nitrogenous base which is adenine. All of the phosphate groups are negatively charged and repel each other, so a high energy covalent bond is necessary to attach these phosphate groups together and keep the forces from pulling them apart.

From a Punnett square you can get the genotypic and phenotypic proportions of the progeny produced from a cross. Cross: PpRr x PpRr. F1: PPRR, PPRr, PPRr, PPrr, PpRr, Pprr, ppRR, ppRr, pprr.

<h3>What is a Punnett square?</h3>

The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.

Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.

In the exposed example, we know that two genes are involved in the cross.

As we can see, there are dominant and recessive alleles for both genes.

Since each genotype in the square results from the combination of parental gametes, we can figure out which are the parental genotypes.

For instance, let us consider the provided genotypes

PPRr.

We can assume one of the parents provided a P and a R dominant alleles, while the other parent provided another P allele but a r recessive allele.

PR + Pr ⇒ PPRr

ppRr.

One of the parents provided a p recessive allele and a R dominant allele, The other parent provided another p allele and a r recessive allele.

pR + pr ⇒ ppRr

pprr.

Both parents provided p and r recessive alleles.

pr + pr ⇒ pprr

From this information, we can assume parents are heterozygous for both genes.

Cross:

Parentals) PpRr x PpRr

Gametes) PR, Pr, pR, pr PR, Pr, pR, pr

Punnett square) PR Pr pR pr

PR PPRR PPRr PpRR PpRr

Pr PPRr PPrr PpRr Pprr

pR PpRR PpRr ppRR ppRr

pr PpRr Pprr ppRr pprr

F1) 1/16 individuals are expected to be PPRR

2/16 individuals are epected to be PPRr

1/16 individuals are expected to be PPrr

2/16 individuals are expected to be PpRR

4/16 individuals are expected to be PpRr

2/16 individuals are expected to be Pprr

1/16 individuals are expected to be ppRR

2/16 individuals are expected to be ppRr

1/16 individuals are expected to be pprr

For a better understanding, you will find the Punnett square in the attached files representing the parental gametes with different colors, and the resulting genotypes with a combination of these colors.

In this way, you will notice which gamete comes from which parent.

In flowering plants, sperm cells are made by the:<br><br> ovary<br> cone<br> spore<br> anther

77julia77 [94]

Answer:

Animal life cycles have meiosis followed immediately by gametogenesis. Gametes are produced directly by meiosis. Male gametes are sperm. Female gametes are eggs or ova.

The plant life cycle has mitosis occurring in spores, produced by meiosis, that germinate into the gametophyte phase. Gametophyte size ranges from three cells (in pollen) to several million (in a "lower plant" such as moss). Alternation of
