A variety of opium poppy (Papaver somniferum L.) having lacerated leaves was crossed with a variety that has normal leaves. All
Ainat [17]

Answer:

The correct answer is-

F1 -  AaBb (lacerate)

F2 - A_B_; A_bb; and aaB_ (lacerate)

     - aabb (normal)

2. Two genes, with a dominant allele at either or both loci.

Explanation:

The given information gives THE following data:

Dominant: Lancerate leaves - AABB

Recessive: normal leaves - aabb

F1 has - all Lacerated leaves - AaBb

F2 by selfing F1:

         AB               Ab         aB         ab

AB    AABB        AABb      AaBB    AaBb

Ab     AABb       AAbb      AaBb     Aabb

aB     AaBB       AaBb       aaBB     aaBb

ab     AaBb       Aabb       aaBb      aabb

Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94

And normal 1/16 = 0.062 is almost same as 16/265 = 0.060

Thus, the genotypes of -

F1 -  AaBb (lacerate)

F2 - A_B_; A_bb; and aaB_ (lacerate)

     - aabb (normal)

Which amino acid chain would be produced by the dna base sequence below?
Oliga [24]

In DNA, there is a code for the sequence of three bases for the placement of certain amino acid in a protein chain.<span> The amino acid chain that can be produced by the DNA base sequence of C-A-A-G-T-T-A-A-A-T-T-A-T-T-G-T-G-A would be based on the DNA code CAA is valine, GTT is glutamine, AAA is phenylalanine, TTA is asparagine, TTG is asparagine and TGA is threonine. </span>

If a molecule of DNA has 30% Adenine how much of the other bases will be present?
anygoal [31]

Answer:

If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.

Explanation:

When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.

A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.

Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.

Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:

  • <em>Adenine 30%. </em>
  • <em>Thymine 30%. </em>
  • <em>Cytosine 20%. </em>
  • <em>Guanine 20%. </em>
  • <em>Total ..... 100% </em>

In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
