1 answer:

4 0

Sites within the human genome where a short nucleotide sequence is repeated many times in a row are known as short tandem repeats.

DNA sequences with 2 to 6 base pairs are known as short tandem repeats (STRs), and they are dispersed throughout the genome. Multiple repetitions of these brief sequences are possible, and the number of repetitions varies greatly between people. The capacity to distinguish one sample from another is made possible by the great variability.

The Y-STR method's primary benefit is its capacity to identify the male component even in severe male-to-female DNA mixes. The number of semen donors for combinations of two or more male persons can be determined using it, as well as for quickly screening a large number of stains.

Due to their occasionally poor biostatistical efficiency and the potential to detect one or more genetic discrepancies that might potentially be explained by mutational events, STRs have a few drawbacks when examining genetic links in deficient cases.

The most common term limit across the states that have imposed them is ________ years.

Klio2033 [76]

Under consecutive term limits , a member can serve for solely a special length of time in both the kingdom house or the kingdom senate, most oftentimes eight years.

<h3>How many states are in the Senate?</h3>

Each nation is equally represented by way of two senators who serve staggered phrases of six years. There are currently one hundred senators representing the 50 states.

<h3 /><h3>What is the distinction between the House and the Senate?</h3>

Senators represent their complete states, but individuals of the House characterize individual districts.

The variety of districts in each state is decided by means of a state's population. Each state has a minimal of one representative in Congress. The House and Senate have advanced into very exclusive bodies.

Developmentalists divide late adulthood into three separate categories because the three groups vary widely in their functioning. Which group is at the highest risk for social isolation?

a. oldest-old

b. old

c. old-old

d. young-old

Adulthood is the period of human lifespan in which people reach full physical and mental maturity. Adulthood usually begins around age 20 or he is 21. From around 40 years old to middle age, around 60 years old to reach old age.

Most countries set the age of majority at 18 years. However, it is important to note that this is not the case for all countries. Similarly, in the US, this varies from state to state. Most states set the age of majority as 18.

According to scientists, puberty was previously thought to end when he was 19, but now it lasts from the age of 10 until he is 24. Adolescents continuing their education longer and delaying marriage and parenthood are fueling widespread perceptions about the onset of adulthood.

A 3-year-old child exhibited some early indication of Turner syndrome, which results from a 45,X chromosome composition. Karyoty

quester [9]

Answer:

The answer is mitotic nondisjunction of X Chromosomes.

Explanation:

Nondisjunction is a type of error that occurs resulting in daughter cells with chromosome numbers that are abnormal (aneuploidy). Due to the error in chromosome numbers, it gives rise to conditions such as Down Syndrome (Trisomy 21) and Turner Syndrome (Monosomy X). Nondisjunction can be caused by;

1. Failure of separation to occur in a pair of homologous chromosome during meiosis I.

2. Failure of separation between sister chromatids in Meiosis II.

3. Failure of separation between sisters chromatids in mitosis.

This gives the 45,X in Turner syndrome. The other X chromosome is partly or completely missing. Hence, the female is born with only one X chromosome.
