Which statement about DNA replication in eukaryotes is true?

Group of answer choices

Nucleotides are added from beginning to end of one strand, from 5' to 3', and then to the other strand.

Errors that occur during DNA replication are repaired by DNA polymerase.

DNA helicase adds nucleotides with complementary bases to the strand of DNA that is being synthesized.

DNA replication only occurs in somatic cells.

Nucleotides are added to the 5' end of the growing DNA strand.

what is a synopsis that includes a type of dynamic or static stretch and why is this a beneficial stretch?

The molecular weight of methylene blue is 320 g/mol. The concentration of the original sample was 0.005 mg/ml in 10 ml. Determine the molarity (M) of your original sample and each dilution.

Original:
Dilution 1 (1:2 add 3mL of methylene blue + 3mL of water) :
Dilution 2 (1:4 use 3mL of of 1:2 solution + 3mL of water) :
Dilution 3 (1:8 use 3mL of 1:4 solution + 3 mL of water) :
Dilution 4 (1:10 use 0.5 ml of the original methylene blue + 4.5 mL of water) :

Please show all work!!

Directional selection acting upon a favored recessive allele:

a) fixates quickly because heterozygotes do hold an advantage

b) fixates quickly because heterozygotes don't hold an advantage

c) takes time to fixate because heterozygotes do hold an advantage

d) takes time to fixate because heterozgotes don't hold an advantage

e) none of the above

In lab this semester, we have examined several cellular molecules and activities including, but not limited to, cyclosis in Elodea, Protein concentration in various food sources, bovine serum albumin and the relationship between protein concentration and absorbance, Betacyanin and membrane permeability, B-galactosidase and enzyme function, yeast cell growth, and RNA production in cells.

Describe how one of more of the databases/programs utilized in this lab exercise (pBLAST, PDB, DeepLoc, KEGG) could be used to gain information about one of these processes or molecules. Be specific and explain your answer.
