Explanation:
If DNA replication does not occur, then the cell cycle will not proceed to the next stage and the subsequent division will not happen. It will lead to cell death.
Answer:
Explanation:
<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>
A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.
A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:
<em>Bb x Bb</em>
<em> BB 2Bb bb</em>
1.
(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.
Probability of having a girl = 1/2
Probability of being a secretor = 1/4
<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8
(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.
Probability of having a girl = 1/2
Probability of being a nonsecretor = 3/4
<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8
2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>
= 3/4 x 3/4 = 9/16
Amino acids have the structure
COOH-C(H)(R)-NH2
The differences are in the R-groups where different functional groups in the r-groups of each amino acid causes them to have different properties (ie. some are acidic and some are basic)
A tissue is a group of similar cells and their intercellular materials in a discrete region of an organ performing a specific function. <span>There
are five levels of organization and these are the cells, tissues, organs, organ
systems and organism. The most complex is the organism having the rest of the
organization in it and the least complex is the cell, the basic unit of
structure. The human body tissue is an organized group of cells that is formed to create a muscle or an organ. There are four types of human body tissue: muscle, epithelial, connective and nervous tissue. Each function according to how they are grouped.</span>
Free energy is a composite function that balances the influence of energy vs. entropy.
