Explain how many different cell types are able to respond to the same cell signalling compound.
Describe what the endothelial cells of a capillary look like.
Mutations in a gene’s DNA base sequence can alter the primary structure of proteins. Use the information in Table 5.1 and Table 5.2 to suggest what happens to the primary structure of cathelicidin LL-37 when the base T in the middle of the triplet at position 5 is replaced by base A.
Mutations in a gene’s DNA base sequence can alter the primary structure of proteins. Use the information in Table 5.1 and Table 5.2 to suggest what effect the deletion of base T from the triplet at position 2 has on the primary structure of cathelicidin LL-37.
Mutations in a gene’s DNA base sequence can alter the primary structure of proteins. Use the information in Table 5.1 and Table 5.2 to suggest what effect the insertion of base G between bases G and T in the triplet at position 3 has on the primary structure of cathelicidin LL-37.
The genetic code is described as universal. Explain why the genetic code is described as universal.
Use Table 5.2 to explain why some mutations do not affect the primary structure of a protein.
