So white blood cell’s(WBCs for short) main job is to fight infections.
They do this by swallowing the infection.
You see,WBCs do not have a permanent shape.this means that they enlarge and decrease size of parts of their body.So they grow two long arm like structures called pseudopodia which swallow the infection.(pseudopodia means false feet).
You can see the process in the photo I attached from google
Most people afflicted with recessive disorder with recessive disorders are born to parents who are not affected at all by the disease. Most genetic disorders of humans are caused by recessive alleles. Dominant alleles on the hand cause lethal disorders, however they are less common compared to the recessive alleles disorders, this is because most individuals carrying a lethal dominant allele have the disorder and they die before pass it to the offspring, while the individuals with the recessive lethal genes are more likely to be healthy and reproduce.
Answer:
2. tRNAQ binds the A site of the ribosome.
1. The polypeptide is transferred to tRNAQ.
4. The ribosome shifts, with tRNAQ still bound.
3. tRNAQ binds the P site of the ribosome.
4. The ribosome shifts, with tRNAQ still bound.
5. tRNAQ binds the E site of the ribosome.
Explanation:
tRNAQ first lands on the A site of the ribosome. It carries an amino acid according to the exposed codon on A site. A bond is formed between the amino acid of A and P site such that the polypeptide is transferred to tRNAQ. The ribosome shifts now and tRNA Q moves to P site from A site while still bound to mRNA. Another tRNA enters the A site and the above process is repeated which finally transfers the polypeptide chain from tRNAQ to new tRNA. tRNAQ has no attached polypeptide now and is ready to leave the translation complex. The ribosome shifts again with the tRNAQ still bound to mRNA. tRNAQ enters the E site from P site and finally leaves the translation complex by exiting the E site.
