After another enzyme (a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand. ... DNA ligase joins pieces of DNA together, mainly joins Okazaki fragments with the main DNA piece.
I believe it’s because of San Andreas fault line if that helps
Sample Response:
Bacteria are helpful because they produce oxygen, which our bodies need to breathe, and they help us to digest the food we eat. Bacteria are also helpful because they are used in medicine to help us overcome disease. Bacteria are harmful because they can cause tooth decay and illnesses that can be either common or quite serious.
This is a sample response, so it's 100% correct. Peace!
Gametic cells
Mutations on somatic cells cannot be passed down to offspring. Rather mutations born on gametic cells are what can be passed down. This is because gametes are the cells involved in fertilization to form zygote that develops into individual organisms.
Explanation:
Mutation on gametic cells can occur within the time from the pre-gametic cell to the formation of a mature gamete such as sperm or egg.
Radiation from nuclear reactor accidents in Japan in April 2011, may damage the cell of the body both somatic and gametic. But only those in the gametic cells are passed down Children born to these Japanese people. Radiation causes double-stranded breaks in DNA that are hard to repair by repair mechanisms in the cell leading to mutations.
