Answer:
Green peas if it does not have a dominant allele for yellow peas.
Explanation:
In pea plants, yellow is the dominant allele color of peas and green is the recessive allele color of the pea. So the genotype that makes yellow color pea is YY or Yy and the genotype that is responsible for producing green color pea is only YY.
This shows that homozygous dominant or heterozygous dominant condition gives rise to yellow color pea and only homozygous recessive condition would give rise to green color pea plants.
Therefore if a pea plant has the recessive allele for green peas it will produce green peas if it does not have a dominant allele for yellow peas.
Answer:
A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA.
Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
