Answer
The organism should be name as bacteria.
Explanation
Peptidoglycans is the characteristics features of bacterial cell its absent in cell wall of archaea, fungi and plant cell. Bacteria can also make amino acids. There are some bacteria who can prepare their own food in the presence of sunlight, i.e purple phototrophic bacteria, green sulphur bacteria, green filamentous bacteria etc. these bacteria contain photosythertic pigments called bacteriochlorophyll.
Answer:
Transportation of substances in cells, where they travel against the concentration gradient. However, it requires ATP to do so.
Explanation:
Answer:
The correct answer would be mitosis or M phase.
Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.
It is primarily divided into four stages:
- Prophase
- Metaphase
- Anaphase
- Telophase.
It results in the equal distribution of chromosomes into two daughter cells.
It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
