Why does each offspring get 2 alleles for a trait?

Answers

Answer 1
During meiosis, chromosome pairs are split apart and distributed into cells called gametes. Each gamete contains a single copy of every chromosome, and each chromosome contains one allele for every gene. Therefore, each allele for a given gene is packaged into a separate gamete.

What happens to the genetic material before the cell divides

Answers

Because each chromosome is made from a single molecule of 'DNA', before a cell divides itself, it had to replicate and copy its DNA. This makes it so that after cell division, each new cell holds an exact copy of the genetic material from the original cell.

The graph above shows the initial rate of an enzyme-catalyzed reaction at
different substrate concentrations in the presence of a constant
concentration of the enzyme.

Connect the primary structure of the enzyme to its overall shape.

Answers

The overall shape of an enzyme changes after the attachment with the substrate.

Enzymes are proteins composed of amino acids that linked together in one or more polypeptide chains. This sequence of amino acids in the form of  polypeptide chain is known as the primary structure of an enzyme.

The tertiary structure is the enzyme's overall three dimensional structure, which occurs due to interactions between the R groups of the amino acids that make up the protein and the active sites of the substrate with which the enzyme can attach so we can conclude that the overall shape of an enzyme changes after the attachment with the substrate.

The primary structure of enzymes determinies their functions and their secondary and tertiary structures. R groups remain in the center of the molecule and stabilize the structure.

--------------------------

To answer this question, we need to remember that enzymes are proteins, and hence, they share many properties. From now on, we will refer to the enzyme as proteins or molecules.

AMINO ACIDS

Amino acids are organic molecules. They are composed of a central carbon, one hydrogen atom, one carboxyl group (COOH), one amine group (NH2), and one R group.

The composition of the R group is what makes them different from each other.

PROTEINS -enzymes-

Proteins are amino acid polymers linearly arranged and connected by peptidic bonds. These molecules characterize by their different structures.

The peptidic bond is the union of two amino acids by their carboxyl and amine groups.

The R group of each amino acid is involved in stabilizing the molecule through their interactions.

The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.

Protein functions also depend on the aminoacids sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

 

PROTEIN STRUCTURE

The primary structure refers to the sequence in which the amino acids are arranged in the chain.

The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds.

The three-dimensional structure makes them even more stable in the environment and capable of properly accomplishing their biological role.  

When proteins are composed of more than one polypeptide subunit, they arrange in a fourth structure, named quaternary structure.

The hydrophilic R-groups remain in the center of the molecule, facing the protein interior, and avoiding interaction with water.

Answer:

Explanation:

The strength in the figure is the figure shows where mitosis occurs in the cell cycle and the figure shows stem cell differentiation. Thus, option D is correct.

What is mitosis?

A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic process. The cell's contents are typically evenly divided into two daughter cells with identical genomes after mitosis.

A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.

Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.

Therefore, Mitosis occurs after G2 stage in the cell cycle.The strength in the figure is the figure shows where mitosis occurs in the cell cycle and the figure shows stem cell differentiation. Thus, option D is correct.
