Answer: A. Heat within the Earth
Explanation: the earth’s crust floats on liquid rock. The convection currents caused by the Earth’s rotation cause movement at the surface.
I believe the answer is that the turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
A hairpin loop is an unpaired loop of messenger RNA that is created when an mRNA strand folds and forms base pairs with another section of the same strand. Intrinsic termination of transcription in E.coli involves the formation of an RNA hairpin in the nascent RNA. The hairpin plays a central role in the release of the transcript and polymerase at intrinsic termination sites on the DNA template.
Answer:
A) altering the nucleotide sequence of the DNA fragment
Explanation:
Gel electrophoresis is a technique to separate the DNA fragments on the basis of their charges and size. DNA fragments are made to migrate through a gel in an electric field. DNA has nucleotides and the presence of phosphate groups makes it a negatively charged molecule. In the gel electrophoresis, DNA fragment migrates through the gel toward the positive pole. Also, the gel slows down the large molecules more than the small molecules. Therefore, the DNA fragments are separated by size. However, the sequence of the nucleotide of DNA fragments does not affect the rate of their migration in the gel.
The answer is the Bursae. A bursa (plural bursae) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous synovial fluid. It provides a cushion between bones and tendons and/or muscles and also reduces friction. The major bursae are located next to the tendons near the large joints, such as elbows, shoulders, hips, and knees.
