Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.
hope it helps btw i did this test and i got it correct
check my screenshot below
please mark me brainliest
Explanation:
This is a false statement.

It depends if it is a carrier or not, and if the trait is recessive or dominant trait
Knowing that she is already 75 years old, even though we don't know her health conditions, we can conclude that the vitamins might help her to avoid any deficiency related to minerals and vitamins, and it might also help her if she has an alimentary restriction meaning that she can't it a food that contains a needed vitamin or mineral.
Hope it helps,
Happy homework/ exam/ study!
Answer:
A. You remind him that a mutation that increases the expression of a single proto-oncogene is generally not sufficient to cause cells to become cancerous. He should also cause some mutations in the mouse's DNA that cause increased expression of some of the mouse's tumor-suppressor genes.
Explanation:
To begin, mutation can be defined as the changes in genetic composition and/or structure of an organism. Now, we have a scenario a strain of mutant mice is developed in a bid to culture cancer and develop cancerous treatment to the effect. Thus, after causing mutation in a mouse, it is disappointing to know that in spite of this, there's no cancer development.
Hence, it is in the light of this that the scientist need to be reminded that a mutation that increases the expression of a single proto-oncogene is generally not sufficient to cause cells to become cancerous. He should also cause some mutations in the mouse's DNA that cause increased expression of some of the mouse's tumor-suppressor genes.
Option A is therefore the most fitted.
