During nitrogen fixation, bacteria breaks nitrogen gasses down into a usable form for plants.
I think the answer is false!
Answer:
a. True, b. False, c.True, d. True
Explanation:
a. Base excision repair is started by a DNA glycosylase that recognizes the changes and removes the altered base by cleavage of the glycosidic bond binding the base and the deoxyribose sugar together.
b. Nucleotide excision repair works by a cut-and patch mechanism that removes their heavy lesions, including pyrimidine dimers and nucleotides . Endonucleases are responsible for the lesion of the damaged strand.
c. Nucleotide excision repair is initiated by the proteins namely UvrA, UvrC, and UvrB in Escherichia coli.
-UvrD (helicase II) later removes the damaged strand
-DNA polymerase I (PolI) fills in the resulting gap.
d. DNA glycolases removes the damaged nitrogenous base.
-It leaves the sugar-phosphate backbone intact and thus creating an apurinic/apyrimidinic site, which is commonly referred to as an AP site.
e. Xeroderma pigmentosum complementation group A(XPA)
-This is an essential protein in the nucleotide excision repair pathway.
- It helps to make a pre-incision complex along with other proteins.
The question is incomplete. The complete question is:
In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait. What is a percent chance that the pea plant will have green pods.
Answer:
100%
Explanation:
Let's assume that the allele "G" gives green pod color while the allele "g" imparts yellow color to the pods. The genotype of the heterozygous plant would be "Gg". A cross between heterozygous green plant (Gg) with homozygous dominant (GG) plant would produce progeny in following ratio=
Gg x GG= 1/2 GG (green): 1/2 Gg (green)
Therefore, there are 100% chances that the progeny plant will have green pods.
It means that they are safe, wholesome, and correctly labeled and packaged.
