777dan777 [17]

Answer:

243

Explanation:

Let us assume the genotype of individual with five genes is AaBbCcDdEe

If we look at the simple mono-hybrid cross between two gene pairs let us say Aa and Aa, the following genotypes will be produced

Aa * Aa

AA, Aa, Aa, aa

So total three different type of genotypes will be produced i.e AA, Aa, and aa

Like wise cross between Bb and Bb will produce BB, Bb, bb

Product of Cc and Cc will produce CC, Cc and cc

Product of Dd and Dd will produce DD, Dd, dd

Product of Ee and Ee will produce EE, Ee, ee

So in total there will be 5 such groups which will assort independently/

Thus, the probability will be

3 * 3* 3*3 *3\\= 3^5\\= 243

The sides of the DNA ladder are made up of a phosphate and:
lesya [120]

Answer:

A sugar called deoxyribose.

Explanation:

DNA is made up of molecules called "nucleotides". These are:

  • A phosphate group
  • A pentose sugar [deoxyribose]
  • A nitrogen-containing base [adenine, thymine, guanine and cytosine]

Thus the first option is the right answer.


Reasons why the other options are wrong:

"A plasma called haemoglobin" is wrong as plasma and haemoglobin are related to the blood.

"A chemical called nucleic acid" is wrong as it is not what DNA's made up of. DNA and RNA are nucleic acids themselves.

"An acid called chlorophyll" is wrong as chlorophyll is related to plants.
