Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
Answer: Tropical rain forests experiences no seasons because it is just hot all year round while temperate rain forests experiences four seasons. Tropics also receive the most sunlight in the planet while temperate rain forests receive light at a slanted angle.
So here we have two heterozygous organisms that will mate. You can put them into a Punnet square, just to be sure of your answers and to find all possible genotypes :
R r
R RR Rr
r Rr rr
So you have RR, Rr and rr as your possible genotypes.
Answer: That a STD is not contagious but can be given by blood bond in other words like if you kiss someone and they have blood on there lip or a sore you can get it like that or if you have finger to finger for example holding hands and they have a little wound there would be a 57% chance they would get the STD. Hopes this helps!
Explanation:
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.
