Answer:
The correct answer is option D.
Explanation:
Linkage mapping is the mapping process in which the genes present on the chromosomes are mapped on the base of their linkage. The linkage mapping helps in calculating how frequent recombination occurs using testcross.
Linkage mapping does not utilize the information that is on DNA sequences, however, it helps in assuming the distance of two linked genes is proportional of the recombination frequency. By the recombination, frequency mutations can be found and study.
Thus, the correct answer is option D.
Answer:
Greenhouse gases
Explanation:
Teddy is working for a nonprofit organization that urges people to stop using products with CFCs. Through this Initiative, Teddy's organization hopes to reduce the concentration of greenhouse gases in the atmosphere.
Greenhouse gases deplete the ozone layer thereby causing global warming as a result often increase in the intensity of Sun rays reaching the earth.
Example of greenhouse gases include chlorofluorocarbon, nitrogen, water vapor etc
Answer:
The word adapt means to get adjusted to a change.
yes, survival in a certain environment is similar to evolution. Both must use adaptation in order for life to keep living through changes in the environment. Each help life sustain itself in a very unique way.
Explanation:
The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.
More differences between prokaryotic and eukaryotic transcription:
• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,
• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).
• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.
• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.
