How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene?
Bogdan [553]

Answer:

Every human has a couple of genes that will be separated when they make gametes. A baby will get one gene from each parent (one sperm and one egg).  

Sickle cell gene is inherited by an autosomal recessive pattern, which means you need both defect genes to get the disease. The person with 1 defect gene can survive and live like normal. This person called a carrier because they carry one defect gene.

Someone that carries one defect gene can come as a result if you cross normal or carrier genotype (AA/Aa) with a carrier(Aa), or with homozygote recessive that carries 2 defect genes (aa). The person will get one healthy gene from the first parent with normal genes, and one defect gene from the second parent.

As a ribosome translocates along an mrna molecule by one codon, what happens after it?
erastova [34]

Answer:

The tRNA is released from the E site of the ribosome and the elongation process finishes while the termination process starts.

Explanation:

When the translocation process is finished the tRNA that is in the E site  of the ribosome is released and the A site of the ribosome reads a stop codon in the mRNA in order to finish the elongation process and start with the termination process.  In the termination process  a termination factor joins the stop codon, the ribosomal subunits split apart, the protein and the tRNA dissociate from one another and the tARN is not in the P site of the ribosome anymore.
