Which of the following molecules directly participates in the process of translation?
pogonyaev

Answer:

mRNA, tRNA, and rRNA

Explanation:

Translation is the second process of gene expression involving the synthesis of proteins from mRNA strand in the ribosomes. mRNA is the template for the translation process to occur. However, other certain molecules are necessary for the occurrence of translation.

The molecules that directly participates in the process of translation include:

- mRNA, which is transported from the nucleus into the cytoplasm (ribosomes) to be read.

- tRNA, this is a type of RNA present in the ribosomes whose function is to read the codons of the mRNA and carry corresponding amino acids to the peptide chain.

- rRNA, is another type of RNA that makes up the ribosomes and functions in the synthesis of proteins from the amino acids.

A randomly mating population of 100 dairy cattle contains a recessive allele that causes dwarfism. If there are 16 dwarf calves
hichkok12 [17]

Answer:

Frequency of heterozygous carriers of the allele in the entire herd is 0.48 i.e 48 out of 100

Explanation:

It is given that a recessive allele pair produces a dwarf cow.

Let this recessive allele be represented by "t" and the dominant allele for tall height trait in cows be "T".

Given

Total population of randomly mating cows = 100

Total number of dwarf calves in the population = 16

Frequency of genotype "tt" producing dwarf calves is represented as q^2 in HW equilibrium equation.

Here

q^ 2 = \frac{16}{100} \\q^2 = 0.16

Frequency of recessive allele is equal to "q"

q = \sqrt{0.16} \\q = 0.4

As per first equilibrium equation of HW,

p + q = 1\\p + 0.4 = 1\\p = 1-0.4\\p = 0.6

Frequency of genotype "TT" producing dwarf calves is represented as p^2 in HW equilibrium equation.

p^2 = 0.6^2 \\p^2 = 0.36

As per HW's second equilibrium equation

p^2 + q^2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.36 + 0.16 + 2pq = 1\\2pq = 1-0.16-0.36\\2pq = 0.48

Frequency of heterozygous carriers of the allele in the entire herd is 0.48 i.e 48 out of 100
