My science teacher told me a couple of days ago that is true
Answer:
B. Early Eukaryotic cells engulfed mitochondria and chloroplasts
Explanation:
Mitochondria and Chloroplast are organelle that are found in cells of higher animals. Chloroplast are found almost exclusively in plants and mitochondria is found in animal cells. The function of these organelles are to produce energy to the cells, and by extension, the organism that they live in.
Unique features of these organelles show that they have their own DNA and divide and multiply on their own. This strongly suggest that they were once free living prokaryotes and were engulfed by larger cells and a symbiotic relationship began.
As time progressed, these prokaryotes did not require all of their genetic information and this was removed from their system. They kept essential genes and regulatory bodies separate that they needed for their maintenance and function that they provide.
Answer:
The correct answer will be-
3'- T U U C G C T T G U C G C T C C T G U U G -5'.
Explanation:
The formation of the mRNA from the template strand or anti-sense strand is known as the transcription.
The nucleotide in the mRNA is added in the same way as the DNA according to the Chargaff rules which states that A will bind to T and G will bind to C but instead of adenine in mRNA will add uracil.
On the basis of this, the mRNA strand will be-
template strand: 5' A T T G C G A A C T G C G A G G A C T T C- 3'
mRNA strand: 3'- T U U C G C T T G U C G C T C C T G U U G-5'.
