Answer:
Lactase
Explanation:
Lac operon (lactose) is degraded to glucose and galactose by three enzymes :beta galactosidase, galactoside permease and thiogalactosidase transacetylase.
Answer:
Anaphase of meiosis II
Explanation:
I think you are asking during which phase of cell division sister chromatids are mostly likely to fail to separate properly, a phenomenon that can lead to genetic disease.
This is sometimes called non-disjunction, and it is most likely to occur in anaphase during meiosis II. During this stage, sister chromatids of the two daughter cells produced by meiosis 1 are separated and brought to opposite parts of the cell. If something goes wrong at this stage, the sister chromatids can fail to separate properly, meaning the daughter cells do not have the correct number of chromosomes (see attachment).
An example of such a genetic disorder is Down syndrome
Answer:
a.saprotrophs → fungi
b.chlorophyll → green plant leaf
c.bacteria rhizobium → N2 fixing
d.cuscutae → parasites
e.insects → pitcher Plant
f .mango tree → autotroph
g.leaf → food factory of plant.
h. tiny pores present on leaf → stomata.
I .CO2 and water → raw material.
j.mushroom → saprophyte
Gametes of the parents would be:
PpTt : PT ; Pt ; pT ; pt
Pptt : Pt ; Pt; pt ; pt
You can do this easily using the FOIL method on each genotype. Just like in math, F stands for first; O stands for outside; I stands for inside; and L stands for last. I'll do one parent genotype and maybe you will understand how this was done:
GENOTYPE: <em>PpTt</em>
<em>F- </em><em>irst of each pair. P and T</em>
P p T t
Gamete: <em>PT</em>
<em>O </em><em>- utside allele of the pair. P and t</em>
P p T t
Gamete: Pt
<em>I - </em><em>inside alleles of the pair. p and T</em>
P p T t
Gamete: pT
<em>L</em><em>-ast or end allele of each pair. p and t</em>
P p T t
Gamete: pt
DNA?, because everyone’s DNA is unique and different in its own way
