Answer:
To match the features and characteristics.
Explanation:
We can classify these Fungi on the basis of their features and characteristics that resembles to the different divisions of fungi. Fungi are classified in four divisions i.e. the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi). There are specific characteristics of every division of fungi so we have to match the physical features of unknown fungi with these divisions and classify them.
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.
Hello I think the answer is iron nail because it’s usually iron is the best choice
<span>Three types of RNA are:
MRNA:
mRNA is transcribed from a DNA template, and carries coding information
to the sites of protein synthesis: the ribosomes. Here, the nucleic acid
polymer is translated into a polymer of amino acids: a protein.
TRNA: transfers a specific amino acid to a growing polypeptide chain at
the ribosomal site of protein synthesis during translation. Basically
forms the protein.
RNA: provide a mechanism for decoding mRNA into amino acids and to
interact with the TRNA's during translation by providing peptidyl
transferase activity. Basically acts as a coordinator for the actions of MRNA and TRNA. </span>
Hope I helped!
