Answer:
Caulobacter crescentus is a specie of gram negative aquatic bacteria. There is gene called as Ccrm gene in them that is responsible for the the synthesis of Ccrm enzyme that is crucial for the proper cell division of cells. When, there is a mutation in this gene, the bacteria won't be able to synthesize Ccrm enzyme anymore. This causes accumulation of two conserved FtsZ and MipZ proteins in cells and result in severe defects and irregulations during cell division.
Answer:
Nitrogenous bases, the phosphates on the side.
Explanation:
DNA is a chemical in the nucleus that carries genetic codes that will determine a trait.
It is composed of three parts, a four nitrogenous bases, a phosphate group and a deoxyribose sugar.
Together they form a structure that resembles a ladder.
The sides of the ladder are made up of sugar and phosphate backbone.
The rungs are made up of the nitrogenous bases.
Therefore, the nitrogenous base was the one containing the nitrogen.
Another part of the DNA that can be labelled is the Phosphate group found at the sides of the ladder.
Answer:
approximately 200
Explanation:
From the question, we have
probability of red = 0.75
Probability of white = 0.25
We are required to find the probability of 6 red + 2 white plants offspring and after we do we multiply it by 640
We will solve this using the binomial theorem method
(a+b)⁸ = a⁸+8a⁷b+28a⁶b²+56a⁵b³+70a⁴b⁴+56a³b⁵+28a²b⁶+8a¹b⁷+b⁸
The required probability is 28a⁶b²
a = 0.75
b = 0.25
= 28 x 0.75⁶ x 0.25² x 640
= 28 x 0.178 x 0.0625 x 640
= 199.36
Which is approximately 200 crosses would be needed
