Chromatin is a part of the spindle apparatus

Explanation:

Chromosome is not only responsible for genetic material. Chromatin is that substance which consists of protein and DNA. Here DNA carries genetic instruction. Histones are main proteins of chromatin. It is also called the packaging of element for the DNA.

In two forms chromatin exist. One is euchromatin and another is heterochromatin. Euchromatin is less condensed and it can be transcribed. Heterochromatin is highly condensed and typically not transcribed. Chromosomal pathway regulates spindle assembly.

Which best describes the direction of heat?

Andrei [34K]

Answer: Heat ---from a warmer substance to a cooler substance

Explanation: Heat can be transferred from a hotter substance to a cooler substance. This can be done through three methods;

Conduction, Convention, Radiation

Conduction- When substance is been heated movement of particles increases causing collision between hotter particles and cooler particles. This continue until the temperature is in equilibrium. Metal is a good conductor of heat.

Convention- It is often associated with liquid and gases. hotter area of liquid moves and meet with cooler liquid. The cooler liquid then takes place of the hotter liquid until equilibrium is attain. This occurs while boiling water

Radiation - It doesn't need a means of transmission. It is gotten from infared emission. Infared emission increases when temperature increases .

George on one pair of his chromosomes has STRs of lengths 6 and 7, Stephen (his father) STRs of lengths 3 and 6, and Mary (his m

JulijaS [17]

Answer:

Stephen is not his biological father.

Explanation:

DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.

The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.

Thus, the correct answer is option (a).
