Mitosis and meiosis similarities
Artist 52 [7]

The alternation of generations in the life cycle of a plant includes the diploid and haploid multicellular stages. diploid and haploid are copies of the chromosomes. The spores in the plant is unicellular and when they start dividing through mitosis, it produces identical cells. These identical cells are all haploid. Haploid stages contain one set of chromosome from either of the parent. These identical cells create a multicellular system called the gametophytes. A gametophyte is the haploid multicellular stage in the life cycle of a plant. The gametophyte makes the gametes. These gametes are responsible for sexual fertilization. It takes place when a sperm (male gametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploid zygote. Diploid stages contain one set of chromosome from each parent. This is where the sporophyte comes in. A sporophyte is the diploid multicellular stage in the life cycle of the plant. It now contains the two sets of chromosomes from each parent.

The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.

proteins need to be denatured using an anionic detergent such as sds before gel electrophoresis because: select all that apply.
grandymaker [24]

The majority of proteins contain a uniform positive charge, and a uniform neutral charge, and most proteins have intricate three-dimensional structures that might affect how well they travel through the gel electrophoresis. For these reasons, proteins need to be denatured. Here, the right answers are A, B, and D.

Protein separation is accomplished using a molecular technique called sodium dodecyl sulfate-polyacrylamide gel electrophoresis, which operates in the proximity of an electric charge. Proteins are separated using SDS-PAGE according to their electrophoretic mobility. Protein charge, shape, and structure all affect electrophoretic mobility.

To proceed in the direction of the positive terminal, the protein molecules need to have a constant negative charge (anode). The overall charge of a protein is determined by the amino acid content of the protein as well as the charge of the individual amino acids.

Thus, depending on the total makeup of amino acids, the charge may change. Depending on the ratio of different amino acids, the total charge of the proteins can be positive, negative, or neutral. The SDS treatment gives the proteins a consistent, negative charge. Then, according to size, the negatively charged amino acids flow toward the positive terminal.

Complete question:

Proteins need to be denatured using an anionic detergent such as SDS before gel electrophoresis because: Select all that apply.

A - most proteins have a uniform positive charge

B - most proteins have complex three-dimensional structures that can impact their movement through the gel

C - the overall charge of a protein depends on the amino acid composition of the protein and can vary greatly

D - most proteins have a uniform neutral charge

Individuals III-3 and III-4 are expecting their first child when they become aware that they both have a family history of this
ad-work [718]

The genealogy tree which is missing from the question is in the attachment.

Answer: 1) P1 = \frac{1}{2}; 2) P2 = \frac{1}{2}; 3)P3 = \frac{1}{16}

Explanation: 1) According to the genealogy tree, the individual III-3 has a P1 = 1/2, because each of the parents are heterozygous for the condition, since one of the ofspring is affected.

2) For individual III-4, one of the parents is heterozygous for the condition, so the probability of being a carrier is P2 = 1/2.

3) Now, for individual IV-1 be affected, the parents has to be carrier. So, this probability, depends on the probability of each parent being heterozygous and that the individual will be carrying the condition, which means:

P3 = 1/2 · 1/2 · 1/4 = 1/16.

The probability of having the condition is 1/16 or 6.25%.
