Different structure in an organism  are specialized to perform different tasks in the organism depending on their makeup.  A few examples are:

Heart, veins,  arteries  are structures forming  the cardiovascular system and function is to facilitate transport nutrients and oxygen carried by blood all over the body.

Bones, joints, ligaments and cartilage are structures of the skeletal system and their function is support and protection of the body.

Mouth, esophagus. stomach, large and small intestines are structures of the digestive system and their function is to break down food and absorb nutrients.

What occurs during frameshift mutation?
yuradex [85]

Answer:

C) An extra chromosome is added, causing mismatching of the chromosome pairs.

Explanation:

Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.

According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.

In frameshift mutation, the insertion or deletion causes the

normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.

14. Explain why women, and not men, can be carriers for the disease hemophilia. Why do the sons of
miv72 [106K]

Answer: Women are carriers for the disease hemophilia because hemophilia is an X-linked disease. The recessive allele for the disease is found on the X chromosome.

The sons of carrier women get hemophilia because males have one X chromosome and one Y chromosome. The sons of a carrier woman may inherit the affected X chromosome from their mother, and a Y chromosome from their father. They have only one X chromosome and one it's affected, will result in hemophilia.

Explanation: Women are carriers because in most cases, only one of their two X chromosomes are affected. The two female X chromosome is rarely affected.

Daughters of carrier women will not get the disease because they need two affected X chromosomes to manifest the disease. So even if they inherit one affected X chromosome from their mother, the second X chromosome they will inherit from their father will be normal. Therefore, daughters of carrier women can only be carriers.
