Which disorders can be observed in a human karyotype
s2008m [1.1K]

Answer:

Answered below.

Explanation:

A karyotype is defined as the size, shape, and number of chromosomes present in an organism.

An analysis is usually done on a karyotype to see if individuals have abnormal numbers or sizes of chromosomes. Such abnormalities may arise from;

Deletion: which implies that a chromosomal part is missing.

Duplication: where parts of a chromosome are repeated.

Translocation: which occurs when a chromosomal part breaks off and gets attached to another chromosome.

Nondisjunction: in which chromosomes do not separate from the parent cells.

Common chromosomal disorders arising from these abnormalities include;

Down's syndrome

Edwards syndrome

Turner's syndrome

Klinefelter syndrome

Prada-willi syndrome

Cri-du-chat syndrome

Patau's syndrome

iVinArrow [24]

The degree to which chromatin is compacted greatly affects its accessibility for transcription, and thus, gene expression.

<h3>What is Transcription?</h3>

This is the process which involves copying a segment of DNA into RNA in organisms.

When chromatin is condensed, DNA becomes less accessible for transcription factors and vice versa which was why it was chosen as the most appropriate choice.

State two ways in which endocrine glands and exocrine glands differ.
denis-greek [22]

Answer:

The two major differences lies in the function and support system.

Explanation:

The two major differences between an endocrine and an exocrine system are as follows –  

a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.  

For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.

b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
