Answer:
H+
Explanation:
Hemoglobin is the major protein of red blood cells. It has many exposed amino groups and carboxylic groups at its surface. These NH3 and COOH groups serve as weak acids and bases respectively and allow hemoglobin to serve as a buffer to maintain the pH of the RBC cytoplasm.
As the exposed amino groups of hemoglobin protein bind to the H+ ions, the free H+ concentration of the cytoplasm of RBC is reduced leading to a buffer action to maintain the pH.
Answer:
b. GGCC
CCGG
Explanation:
Restriction enzyme cleaves DNA at the restriction site. Restriction site has 4-8 nucleotide base pairs which are recognized by the restriction enzyme. This site usually has a palindromic sequence which means that the sequence is read as same on both the strands in 5' to 3' direction. Palindromic sequence is used because it increases the chances that both the strands are cut. Enzyme is also able to recognize the sequence no matter from which side it approaches the DNA. The enzyme also works as homodimers sometimes so having the same sequence makes the dimers easier to recognize it. Here, the sequence is GGCC in 5' to 3' direction on both the strands making it a palindromic sequence. Hence it is most likely to be recognized as a cutting site for a restriction enzyme.
I think the probability would be 50% bc there are four options FF Ff fF and ff. Half of those are heterozygous (the child would be a carrier). So I think it's 50%. However, if we already know that the child will not have the ff combination, then we could say that there are only three other options (so maybe it's 60%?) but that's probably just me being a smartass.
There are around 75,000 types of fungi!
The phase during which sister chromatids aggregate along the equator of the cell is called the metaphase.
The image shows the process of cell division through mitosis. The mother cell divides into two genetically identical daughter cells in mitosis. There are four main phases in the mitosis process. They are: prophase, metaphase, anaphase and telophase. In the metaphase, the highly condensed sister chromatids line up along the equator of the cell by binding to the microtubles that form the skeleton of the cell. These kinetochores line up the chromatids at the equator to initiate their separation.
