There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.

A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a ___
joja [24]

Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.

Explanation:

CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.

In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.

The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.

A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.

A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein

What is the effect of an increased concentration of calcium ion in the sarcoplasm?
ICE Princess25 [194]

Answer:

When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.

andrey2020 [161]

The question is incomplete as it does not have the options-

A) Gamma-aminobutyric acid (GABA)

B) Acetylcholine

C) Dopamine

D) Serotonin

Answer:

The correct answer will be option- Dopamine

Explanation:

Parkinson's disease is one of the movement disorders which gets worse with time. The disease is caused due to the degeneration of the neurons in the brain which are responsible for the body movement.

Although many brain areas are affected the most common result is due to the loss of neurons in the substantia nigra in which the neurons produce a neurotransmitter called dopamine which is responsible for the body movements.

Thus, Dopamine is the correct answer.
