(03.05 MC)<br> In which of the following ways is DNA replication similar to transcription?
Nezavi [6.7K]

Answer: <u>D.  Thymine is used in replication while uracil is used in transcription.</u>

Explanation:

Genetic information is stored in double-helixes of DNA molecules (Doxyribonuclease). In replication, two daughter strands of DNA are copied from the parent strand, while in replication, instructions stored within DNA are copied into a different form, called mRNA  or messenger RNA.

Nucleotides are monomers comprising DNA, a nucleic acid that along with RNA, a ribose sugar-containing nucleotide, acts as a storage molecule to encode proteins. 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogen bases are found in nucleotides:

Adenine (A)

Guanine (G)

Cytosine (C)

Thymine (T).  

Uracil (U) found in RNA

While <em>both contain four nucleotide bases, </em> in RNA, uracil replaces thymine... The DNA nucleotides are involved in replication while RNA nucleotides drive transcription,

A rooster with gray feathers is mated with a hen of the same phenotype. Among their offspring, 15 chicks are gray, 6 are black,
m_a_m_a [10]

Answer:

Alleles for feather colour exhibit incomplete dominance or co-dominance.

50% gray offspring + 50% black offspring

Explanation:

<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>

Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.

Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.

15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.

Bb   x   Bb = 1BB, 2Bb, and 1bb

Crossing the gray rooster (Bb) with a black hen (bb):

Bb   x   bb = Bb, Bb, bb, and bb

          = 2Bb (gray):2bb (black)

50% of the offspring will be gray while the remaining 50% will be black.
