Answer:
RNA polymerase moves along the template strand in a 3'-to-5' direction.
Explanation:
RNA polymerase is an enzyme involved in the synthesis of an RNA molecule from a DNA molecule. The process of synthesis of an RNA molecule is known as transcription which takes place in the nucleus of eukaryotes.
The DNA strand which is transcribed into the RNA molecule is known as template DNA and run from the 3'to 5' end.
The RNA polymerase enzyme binds to the promoter region which initiates the reaction. The RNA polymerase enzyme forms the RNA molecule in 5'to 3' direction by adding new nucleotide at 3'end, therefore, it has to move on the template strand with 3' to 5' direction.
Thus, the selected option is correct,
1- smooth, cardiac, skeletal
2-tendons
3- digestive tract, airways(bronchi and bronchioles), muscles in iris(that change the area of our pupil)
4- skeletal
5- smooth and cardiac
Hope this helps:)
Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.
