Choose the true statement(s) that support(s) the endosymbiotic theory. To be marked correct, you'll need to select all true stat
horsena [70]

Answer:

a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.

c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.

d.Mitochondria and chloroplasts replicate by a process similar to mitosis.

Explanation:

Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.

The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.

Which of the following are the approximate sizes of the DNA fragments for the mother? 620 bp and 300 bp 800 bp and 570 bp 800 bp
antiseptic1488 [7]
<h2>The approimate sizes of the DNA fragments for Mother </h2>

800 bp and 260 bp are the approximate sizes of the DNA fragments for the mother. The appearance or inadequacy of specific identifying places in a DNA specimen produces changeable dimensions of DNA fragments, which are isolated utilizing gel electrophoresis. They are then hybridized with DNA scrutinies that join to a corresponding DNA series in the example.
