Answer:
D
Explanation:
Everything in there pollutes the environment.
Blood, urine, tissue/skin, saliva, hairs, etc.
When there has been an error in copying a DNA, a DNA repair gene fixes its mistakes. However, a person having an error in his DNA repair gene (which are not corrected), it may lead to gene mutations with the possibility of leading to cancer. The mutations of DNA repair gene can possibly be inherited or acquired.
Answer:
The genetic information of living organisms is sequenced in DNA, which allows inheritable factors to be transmitted with each replication process. Proteins play a very important role by intervening in their metabolism during the translation and transcription of information. .
eukaryotic and prokaryotic organisms have different evolutionary sequelae that are reflected in the mechanisms they use for DNA translation, such as in the initial stages, lengthening and termination of sequencing, these differences are imparted by the order of the genes, the ribosome and its structural form and the promoter sequences.
In this way we can conclude that although the eukaryotic genes enter into a bacterium, the type of information that they take may arrive incomplete and this may generate subsequent defects for their operation, but there may be processes that guarantee a better transfer of information with the use of genetic engineering and enzyme management to introduce different bacterial genetic expressions with eukaryotic genes.
Answer:
A. Activated B - cells divide to form memory cells.
Explanation:
The vaccine contains the dead version of the respective virus, so that virus will be inactive and it will become easy for the WBC to kill it and antibodies will be formed.
This is done because if we get infected by the virus, our body cells (WBC) will remember that how they killed the first entered virus (the dead version) and it will be easy for them to kill the active virus as they know the antibodies which were formed to kill the inactive virus.
