The human genome has been estimated to have 20,000 - 25,000 human protein - coding genes.
Before it was thought that the number of genes in the human genome was about 100,000, but with better and more advanced gene finding technology, this number has been revised down to the current estimate, and could continue to drop further.
The human genome has 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 22 autosomal chromosomes plus the sex determining X and Y chromosomes, to make 23 pairs.
Answer:
As these cells are non-photosynthetic, all other organelles would be found in these cells except for chloroplasts which contain photosynthetic pigments used for photosynthesis. A few examples of structures found within these cells would be cell wall, cell membrane, cytoplasm, ribosomes, nucleoloid and many others. Do note that prokaryotic cells do not have organelles with membranes hence they do not have mitochondria or lysosomes or endoplasmic reticulum etc.
Explanation:
Nucleotides can be radiolabeled before they are incorporated into newly forming DNA and, therefore, can be assayed to track their incorporation. In a set of experiments, a student-faculty research team used labeled T nucleotides to study the incorporation of labeled nucleotides into a culture of lymphocytes. They found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. they might conclude from this observation is that the Infection causes lymphocytes to divide more rapidly
- Lymphocytes is a type of immune cell produced in the bone marrow and present in the blood and lymphatic tissue. B lymphocytes and T lymphocytes are the two main types of lymphocytes. T lymphocytes help eliminate tumour cells and govern immune responses, whereas B lymphocytes produce antibodies. A lymphocyte is a white blood cell type.
