Sites within the human genome where a short nucleotide sequences is repeated many times in a row are known as ________.

VikaD [51]

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.

Answer:

In classic research, Dweck (1975) found that boys tend to attribute their poor performance in math to unstable internal factors, whereas girls tend to attribute their poor performance in math to stable internal factors.

Explanation:

Here, we are talking about motives related to attribution. Notice that Dweck found that boys attribute their success in math to unstable internal factors, and girls to stable internal factors.

External and internal are related to the locus of the attribution, the "location" of the cause of success or failure. For instance, an external attribution may be the fact that the test was easy. An internal one may be our own ability in math.

Unstable and stable are related to the stability of the attribution. For instance, cramming for the exam is an unstable attribution, since the effort we put into studying may vary each time. Ability, on the other hand, is a stable one, since it lasts and has consistency.
