The butane combustion equation is: 2C4 H10 + 13O2 → 8CO2 + 10H2 O. Complete hydrocarbon combustion reactions always produce carbon dioxide and...
I have no clue, there is nothing else here to support your question.
Answer:
allelic frequency a = 30%
allelic frequency A = 70%
Explanation:
You are studying a population of sparrows in which the phenotype is determined by a single locus. Only two alleles for this locus are known for this population, which are distinguished by the codes 'A' and 'a'. The distribution of phenotypes in the population indicates that 49% of the population is homozygous 'AA', 42% is heterozygous and 9% 'aa' homozygous. How is the allele frequency for 'A' and 'a' determined based on these observations?
According to the case, the allelic frequency for A and a will be searched with the data:
homozygotes AA = 49%
heterozygotes Aa = 42%
homozygous aa = 9%
Frequency of homozygotes 'aa'
(q 2) = 9/100 = 0.09
we can obtain the allelic frequency of a through the following formula:
a (q) = √0.09
The result will be
= 0.3
we change to percentage
= 30%
we have the following formula
p + q = 1
to find the allele frequency A, represented by p
p = 1 - 0.3
we get the following result
p = 0.7
we change to percentage
= 70%
Which activities? I want to say the nucleus as it is the control center of the cell, but this is a vague question.
Answer:
approximately 150 amino acids
Explanation:
Proteins are produced from genes via a process called gene expression. In this process, the gene-containing DNA is first transcribed into mRNA molecule, which is subsequently translated into an amino acid sequence that makes up the protein molecule.
However, during the translation process, the mRNA molecule is read in a group of three nucleotides called CODON i.e. a codon is made up of three nucleotide/nitrogenous bases. Each codon codes for a particular amino acid.
Since one codon of a mRNA that is three (3) nucleotides long codes for one amino acid, hence, strand of mRNA that is 450 nitrogenous bases long will produce a protein containing approximately (450/3) = 150 amino acids.
