B. Frequent due to fighting between bats
:)
It is characteristic of DNA only because RNA contain Uracil as a base in place of Thymine
Internal, external, and cellular respiration
Answer:
Parental chromosomes A----b and a-----B when fertilized with ab will produce AabB and aaBb - these will be progeny with parental chromosome --- so no recombination.
You are told that map distance is 20cM which is also telling you that recombination frequency is 20% , so % progeny showing recombination = 20%, so % progeny not showing recombination is 100= 20 = 80%. This will be composed of the 2 parental categories, as above so % aaBb = 40%
Explanation:
Answer:
1. Uracil
2. Ribose
Explanation:
DNA and RNA are both types of nucleic acids. Although they are made up of similar constituent molecules, they are slightly different. All nucleic acids have three major constituents viz: nitrogenous base, pentose sugar and phosphate group.
The four nitrogenous bases found in DNA are Adenine, Guanine, Cytosine and Thymine. However, three of this bases are found in the RNA molecule but one different one called URACIL, which replaces Thymine is found. Also, the pentose (five-carbon) sugar found in DNA is deoxyribose while that of RNA is RIBOSE.
