Answer:
The endosymbiotic theory deals with the origins of mitochondria and chloroplasts, two eukaryotic organelles that have bacteria characteristics. Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria, specifically alpha-proteobacteria and cyanobacteria, respectively.
1) The main difference between a prokaryotic cell and a eukaryotic cell isD) the presence of a true nucleus.
2) Which type of cell contains DNA enclosed in a nucleus?
C) plasmid
3) Viruses CANNOT
B) live in bacteria.
Hope this helps.
The answer is C. Alleles form your genetic makup :)
please mark as brainliest! thank you!
Answer:
B. an amino terminal signal peptide
Explanation:
The reactions of the citric acid cycle occur in the matrix of mitochondria. Therefore, all the enzymes required for this pathway are present in the matrix of mitochondria. These enzymes are formed on the ribosomes present in the cytosol and are transported into the mitochondria with the help of cytosolic heat shock proteins. The newly formed mitochondrial proteins have signal sequences present at their N terminal. The proteins to be transported into the matrix have a single signal sequence that at N terminal which is removed by a protease once the enzyme enters into the matrix.
Answer:
meiosis I
Explanation:
Reduction of the number of sets of chromosomes occurs during meiosis I.
During Meiosis I crossing over of genetic material occurs between chromosome pairs
