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

The information carried by a dna molecule is in __________.
Papessa [141]

Answer:

Sequence of nucleotides in the DNA strand

Explanation:

Deoxyribonuceic acid or DNA is a biological material that stores the genetic information of an organism.

DNA encodes the information through the order or sequence of the nuceotides along each strand. Organisms differ from one another because their respective DNA molecule have different nucleotide sequences and consequently, carry different biological instructions.

A DNA strand consists of two polynucleotide chains, composed of four nucleotide subunits. Each of these chains is known as DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together. DNA nucleotides are composed of a 5-carbon sugar (Deoxyribose) to which are attached one phosphate group and a nitrogenous base (Adenine, Guanine, Cytosine and Thymine). The nucleotides are covalently linked together.
