Answer:
single-strand DNA-binding protein
Explanation:
Based on the scenario being described within the question it can be said that these proteins are known as single-strand DNA-binding protein. They are protein mainly in the E. Coli bacteria, and bind to single-straded regions of DNA. They are a main functional part of everything related to DNA metabolism such as replication, recombination, and repair.
Answer:
Plant cells form a cell plate between the two daughter cells. In animal cells, a cleavage furrow is formed between the two daughter cells.
Explanation:
The correct answer is color vision.
The macula lutea is an area near the center of the human's eye retina. It has an oval shape and is responsible for the high-resolution color vision we have under good light conditions. If the macula lutea is destroyed, due to macular degeneration or a retinal detachment, then this color vision is impaired.
A mutation is a rare, accidental or induced modification of genetic information (DNA or RNA sequence) in the genome.
The consequences of a mutation vary according to the part of the genome affected. A mutation is said to be hereditary if the mutated genetic sequence is passed on to the next generation.
In multicellular animals, germline mutations can be transmitted to offspring, whereas somatic mutations do.
Somatic mutations do not affect cells intended for reproduction, so they are never hereditary:
* Post-zygotic mutations are the mutations that appear in the egg after fertilization. They are rarer and are expressed as mosaic in the individual concerned (the mutation will be present only in the daughter cells originating from the mutated embryonic cell).
* Mutations can appear throughout life on the DNA of any cell; they are then transmitted to the line of the daughter cells. These can, in some cases, become tumor cells and then form cancer.
