Artia, spetum, ventricles, valves
Answer:
I, II and III
Explanation:
The melting temperature of a DNA double helix is affected by several factors that affect the hydrogen bonds and /or the other interactions involved in maintaining the helical structure. Two DNA strands of a helix are held together by the hydrogen bonds between the complementary nitrogenous bases. The pH of the solution would affect the hydrogen bonds. If the pH is too acidic, the hydrogen bonds acceptor atoms will accept protons from the solution and would not be able to make hydrogen bonds.
The ionic strength of the solution represents the ions present in it. If the solution has positively charged ions, the negative charges of phosphate residues of the DNA backbone will be neutralized. This would make the double helix more stable. Similarly, a longer DNA strand would have a higher melting temperature as more heat will be required to break more hydrogen bonds as compared to a shorter DNA strand.
Answer:
Answer is 3/16.
Explanation:
If the F1 progeny has red axial flowers this shows us that red and axial genes are dominant. If we say that R is for red dominant gene, r is for white recessive gene.
If we say A is axial dominant gene, a is for terminal recessive gene.
All F1 progeny has AaRr phenotype.
When we cross them, Aa x Aa can have AA Aa Aa aa
When Rr x Rr crossed, RR Rr Rr rr
The F2 progeny can have white axial flowers by having a and R in the phenotype with the possibility having aa= 1/4 , R in the phenotype , the possibility is 3/4.
1/4 x 3/4 = 3/16 in all F2 progeny
They contain genetic information and assist in making proteins
Independent -children
dependent -level type
