It’s easy to understand why multiple bands would be present in the lanes containing DNA that has been cut with restriction enzym
bulgar [2K]

Answer:

These bands represent different confirmation of DNA

Explanation:

pGLO DNA is a plasmid DNA that is used as a vector for genetic engineering. Plasmid DNA is found in supercoiled confirmation in vivo. The double helix forms extra twists to easily fit inside the cells. During isolation of plasmid from the cell, nicks can be introduced in the DNA due to harsh isolating methods or contamination by nuclease. As a result the supercoiled confirmation is changed into circular confirmation. It is bulkier than the supercoiled form and travels more slowly. When both DNA stands get cut at the same place, the DNA gets liner confirmation. In the end, supercoiled DNA runs the fastest on gel followed by linear DNA and then the circular DNA.

The statement is false. Squash and tomatoes are not vegetables, thus they considered as fruits.

Dr. L. Hill conducted a study examining music ability in families; she recorded the concordance rates of music ability of adopte
djverab [1.8K]

Answer:

Option C, Correct Behavior genetics

Explanation:

Behaviour genetics is the study of the influence of both genes and environment on the behaviour of an individual. This study is done to understand how both genes and environment together affect the behaviour of an individual. It is believed that all forms of behaviors are either inherited or learned. Mr. Hill is noting the concordance rates of music ability  for both biological children (who might have inherited this ability from their parents) and adopted children (who might have learned this ability from the musical environment around them)

Hence, option C is correct

What is a main disadvantage in asexual reproduction
zhenek [66]
The main disadvantage is that there is no diversity. Therefore, if a disease starts to wipe out the species, it will affect all of the organisms that the parent plant created.
