Answer:
B) protein synthesis
Explanation:
An RNA codes for protein synthesis. A triplet of nucleotides/bases in RNA helps in adding an amino acid into the protein strand. This triplet of nucleotides is knwon as codon and helps in adding amino acid which is specific to it. For example, AUG triplet codes for methionine while UGG codes for tryptophan. The amino acids get added in protein strand unless a stop codon is reached. Triplets UAA, UAG & UGA are stop codons. Here it may be noted that initially a polypeptide chain is synthesized by RNA but the ultimate goal of making that polypeptide chain is protein synthesis.
Answer:
Changes in allele frequencies over time can indicate that genetic drift is occurring or that new mutations have been introduced into the population.
The answer is 1). Two Tt parent can produce T and t for 50% separately. So for the result, TT has the probability of 50%*50%=25%. The same for tt. And Tt is 1-0.25-0.25=50%.
<span>Here are the missing options for the above question:
</span><span>1. The bacterial culture in test tube D was diluted so much that no pink bacteria were left in the sample.
2. The pink bacteria were not able to get enough energy from the nutrient broth in test tube D to live.
3. The white bacteria outcompeted the pink bacteria for the nutrients in the broth in test tube D.
4. The pink bacteria are sediment growers in nutrient broth and the micropipette could not reach them.
