Dominant phenotype will be expressed on homozygous dominant(BB) and heterozygous(Bb) type. Using hardy-Weinberg equilibrium, the percentage of individual with brown eye would be:
homozygous dominant= BB= 70%*70%= 49%
heterozygous = 2Bb= 2* 70%*30%= 42%
Total brown eyes= homozygous dominant+ heterozygous
Total brown eyes= 49%+42%= 91%
If the dna triplets is atg-cgt, the trna anticodons are Uac-gca.
<h3>Are codons triplets of tRNA?</h3>
The triplet of bases that is complementary to a codon is called an anti-codon the triplet in the mRNA is called the codon and the triplet in the tRNA is called the anti-codon.
Thus, option "D" is correct.

Explanation:
The DNA contains many regulatory sequences that are very important, even though they do not code for proteins.
For example, the expression of every gene is regulated by a region called the Promoter. The promoter sequence, located close by the coding region of the gene, usually binds the RNA polymerase (the enzyme that transcribes genes into mRNA) as well as other proteins necessary for transcription,
The promoter sequence, thus, does not itself code for proteins, but is essential for transcription and must be highly conserved so that the RNA polymerase can find it.
Answer:
cell growth and manipulation
Explanation:
The nucleus of the cell controls cell growth and manipulation. This involves regulating gene expression, initiating cellular reproduction, and storing genetic material necessary for all of these tasks. In order for a nucleus to carry out important reproductive roles and other cell activities, it needs proteins and ribosomes.
