Explanation:think about it
When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. In other words this occurs when heterozyhotes have increased fitness over both homozygotes. A good example is sickcle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
Answer:
it means they are only made up of one cell
Answer:
The correct option is E.
Explanation:
Protein synthesis in living cells is divided into two distinct stages, which are transcription and translation. Transcription occurs in the nucleus where mRNA is formed from DNA. The mRNA then moved into the cytoplasm, where the process of translation takes place. Translation occurs in 5 stages and the accuracy of this process depend on the bonding of the anti-codon to the codon and the attachment of amino acids to tRNA.
tRNA (transfer RNA) plays a vital role in the translation process. It has very specific structures, which have the ability to bind to specific amino acids at one end and an mRNA molecule at the other end. This arrangement ensures that accuracy is maintained by making sure that each amino acid is carried to the appropriate point in the protein that is been synthesized based on the information in the mRNA.
