Answer:
Size of the band varied
Explanation:
In the given question, the options are not provided but based on the information provided in the question, it can be predicted.
When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.
When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.
Thus, the size of the band varied is correct.
Answer:
The correct answer is option A.
Explanation:
Cellular organization is one of the characteristics of life that states that each living organism is made up cell or more than one cell, that is made up by organization of various components such as chemicals like micro molecule that form the macro molecule and these chemical level structural organization is formed together to make cells and this level of organization makes the tissue which is complex to cell but simpler to organ that is makeup of various together.
The makeup of organs is necessary as organs are the structural level that individuals facilitate the function and make up the organ system that is a complex system made up of organs that are similar in their function. The organism is the most complex of all levels.
Thus, the correct answer is option A.
Answer:
Long tail and narrow head.
Explanation:
A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.
The temperature insensitive, thermostable, DNA polymerase was extracted from a bacterium found in hot springs can withstand the high temperatures needed to separate the double stranded DNA and the replication process can continue uninterrupted. The enzyme thermus aquaticus can withstand the high temperature used to separate double stranded DNA, so replication does not need to be interrupted by the need to add more enzymes.
