In what phase of meiosis are sister chromatids separated and pulled to opposite ends of the cell

Answers

Answer 1

Answer: The stage if meiosis where sister chromatids are separated is anaphase II. Once the sister chromatids are separated they are then referred to as unreplicated chromosomes.

Answer 2

Answer:

Just took the test! It is Anaphase ll

In an individual of genotype aa, where are the a and a alleles physically located? view available hint(s) in an individual of genotype aa, where are the a and a alleles physically located? one allele is on one chromosome and the other allele is on a different (nonhomologous) chromosome. one allele is on one chromosome and the other allele is in a different position (locus) on the same chromosome. they are both on one chromosome. one allele is on one chromosome, and the other is in the same position (locus) on the homologous chromosome.

Answers

Answer:

One allele is on one chromosome, and the other is in the same position (locus) on the homologous chromosome.

Explanation:

The genotype of an organism refers to the genetic makeup or complete set of genes. The genes control the trait of an organism and exist in an organism in their alternative form called alleles.

Since the alleles are the alternative form of a gene, therefore, they must be present at the same position called a locus.

These alleles are present on the homologous chromosome in which each homologous chromosome is contributed by each parent.Therefore when the genotype is aa then a and a allele will be present on homologous chromosomes in the same position.

Thus, the selected option is correct.

Adenosine Triphosphate Living organisms store chemical energy in the form of biomolecules. Organisms transform these biomolecules to other forms of energy when needed. For example, chemical energy is transformed into mechanical energy when a muscle uses energy to move. Adenosine triphosphate (ATP) is the most important biomolecule that provides chemical energy. ATP is like a storage unit of chemical energy for the cell. It’s the most abundant energy-carrying biomolecule in cells. The structure of ATP consists of a nucleotide made of an adenine base, a ribose sugar, and three phosphate groups. ATP releases energy when the second and third phosphate molecules are broken, forming adenosine diphosphate (ADP). ADP can also form adenosine monophosphate (AMP), but this reaction releases less energy than the reaction that converts ATP to ADP.

Answers

Answer:

Adenosine triphosphate (ATP) is an essential biomolecule that stores and provides chemical energy in living organisms. It acts as a "currency" for energy transfer within cells. Let's break down its structure and function:

1. Structure: ATP is composed of three main components:

a. Adenine base: It's a nitrogen-containing molecule that serves as a building block of nucleotides.

b. Ribose sugar: This is a five-carbon sugar molecule that is bonded to the adenine base.

c. Phosphate groups: ATP has three phosphate groups attached to the ribose sugar.

2. Energy Storage: The energy in ATP is stored in the bonds between the phosphate groups. These bonds are high-energy bonds, meaning they contain a lot of potential energy.

3. Energy Release: When the cell needs energy, ATP can be hydrolyzed, or broken down, by removing one phosphate group. This results in the formation of adenosine diphosphate (ADP) and an inorganic phosphate molecule. The breaking of this bond releases energy that can be used by the cell for various processes.

4. Recycling ATP: ADP can be further hydrolyzed to form adenosine monophosphate (AMP) by removing another phosphate group, but this reaction releases less energy compared to the conversion of ATP to ADP. ATP can be regenerated by adding a phosphate group back to ADP through a process called phosphorylation. This recycling process allows ATP to continuously provide energy within the cell.

To summarize, ATP is a molecule that stores and provides chemical energy in cells. It consists of an adenine base, ribose sugar, and three phosphate groups. Energy is released when ATP is converted to ADP by breaking the bond between the second and third phosphate groups. ADP can be further converted to AMP, but with less energy release. Through phosphorylation, ADP can be converted back to ATP, ensuring a continuous supply of energy for cellular process
