A gamete will have n=23 chromosomes while a somatic cell is going to have a diploid number of cells, or 2n=46. This is the case because somatic cells are going to receive a copy of chromosomes from each parent, so 23 from the mother and 23 form the father to give 46 total chromosomes. If you are ever given the haploid number and asked for the diploid number, then you can simply double the haploid number.

The correct answer is the "S," or synthesis, phase. The cell cycle consists of six main parts: interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. Interphase, the longest part of the cell cycle, is subdivided into three different phases: G1, S, and G2. G1 comes first; in this phase, the cell simply grows. In the S phase, the cell synthesizes (creates) a new set of DNA using its original genome as a template. In G2, the cell (which now contains two copies of DNA) continues to grow. These growth phases are an important part of interphase because the cell must grow enough to have enough cytoplasm to give to each of its daughter cells at the end of mitosis or meiosis.

A phenotype is a physical trait that can be observed. Thus, eye color (and hair color) are great examples of phenotypes. A genotype describes the genetic traits of a person (e.g. whether that person has the autosomal or recessive alleles of a gene). The genotype of an individual determines his or her phenotype.

The easiest way to solve this problem is to draw a punnet square. The genotypes of the parents are "AO" and "AB". The potential genotypes of their children are "AA", "AO", "BA", and "BO". Children with genotypes "AA" and "AO" will have type A blood. Children with genotype "BO" will have type B blood. Children with genotype "BA" will have type AB blood. Genotype "O/O" is the only one that will result in type O blood. "O/O" is not a possible product of this punnet square. Both the mother and the father must have the "O" allele in order for a child to have genotype "O/O" and type O blood.

This question is essentially asking, "Which of the following is a point mutation of the original sequence?" A point mutation is a mutation in which one base pair of DNA is substituted for another. A point mutation will not change the reading frame of a DNA sequence because it does not involve adding or removing any bases. The only answer choice that is identical to the original sequence with the exception of one base pair being changed for another is 5'GATCACG3', so this is the correct answer.

In RNA, the nucleic acid base adenine pairs with uracil. (In DNA, it pairs with thymine). In both RNA and DNA, cytosine pairs with guanine. Accordingly, RNA will have the same percent uracil as it does adenine—in this case,.

(In this case it will also containguanine andpercent cytosine, because the adenine and uracil together add up toand the remainingis divided evenly between the paired guanine and cytosine (anddivided by two is).

Gametes are germ cells used in sexual reproduction, such as eggs or sperm. They are haploid cells with a chromosome number of, while somatic (non-reproductive) cells are diploid with a chromosome number of.So, if an organism's gametes havechromosomes each, a somatic cell in that organism will have twice that number of chromosomes—in this case,.
