Answer:
Short answer is primers are partially complementary.
Explanation:
Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'
Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'
When we write reverse primer 5' to 3' we can easily see that
3'-TTGGCCAATGG---5' is complementary to the forward primers'
5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
At the Joes injury, the grey matter looks like a butterfly-shaped are. While the white matter has tracts which are either ascending or descending. For example, we have corticospinal which is ascending tract. Grey matter it is the thin cerebral cortex for each hemisphere of the cerebrum and it is composed of interneurons which integrate information.
White matter consists of myelinated axons that lie low below the cerebral cortex.
The two hemisphere connects together by the corpus callosum.
Answer:
This is because of how reproduction works in humans. Male and female sex cells are formed by a process called meiosis, where the diploid chromosomes divide and separate. And so the ratio of male to female births is also 50:50.
