C I did this question before
Answer:B. nucleic acids to amino acids
Explanation: During translation, proteins are synthesized from messenger RNA molecule. Messenger RNA (mRNA) is a type of ribonucleic acid that contains genetic codes which code for amino acids. A genetic code or codon is a triplet of nucleotide (three nucleotide molecules) that codes for a specific amino acid. During translation, the genetic code in an mRNA is read by the ribosome and the information is converted to an amino acid sequence by transfer RNA (tRNA) which gets the amino acid coded for by the codon and attaches it to the growing polypeptide chain.
Transfer RNA is responsible for fetching the correct amino acid coded for by the codon from the cytosol and attaching it to the growing polypeptide sequence.
Yolks are an important component of the eggs since they
nourish the young embryo as it develops into a young juvenile organism. The
yolk is important especially when the embryo is not attached to its parent (in
oviparous organisms) like in humans. Humans embryos are able to get their
nourishment directly from their mothers in the womb (through the placenta)
hence don’t require a yolk (viviparous organisms).
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
