The correct answer is: c. Transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex
The answer is B, fossil fuels take a long time to form and humans use lots of them everyday
They are solitary animals, especially males who do not live in groups, unlike the female which can form small groups of three or four members with their young.
The males are very territorial, so take care of their personal space and the females with whom they mate. To mark their territory, they spray the trees and rocks with a mixture of urine and musk.
Both male and female, they are related only in times of mating and reproduction. There have been cases where the male is responsible for feeding breeding if the mother has died.
The gestation period lasts between 98 and 108 days and give birth to two to four cubs weighing just over a kilo. They have a short life expectancy, as only get to live 10 to 12 years in the wild, but in captivity Natural mortality manage to live up to 26. It is mainly due to the fighting between males
Which type(s) of cells have genetic material that is contained in a nucleus?
- <em>D</em><em>.</em><em> </em><em>Both</em><em> </em><em>plants</em><em> </em><em>and</em><em> </em><em>animal</em><em> </em><em>cells</em><em> </em>
<u>Eukaryotic cells are those cells that retain their genetic material inside the nucleus. They have well defined nucleus. Plants and animals cells are eukaryotic cells.</u><u>.</u><u>.</u><u>~</u>
