Goggle got ur back and I’m not that sure
Answer:
ENDOCRINES circulate in the blood and act at sites distant from their origin;
EXOCRINES pass through ducts;
and PARACRINES act on their local tissue environment.
Explanation:
Exocrines are known for producing external secretions that are released through a duct, usually into the digestive system or the skin
Endocrine are known for producing internal secretions called HORMONES that are transported around the body by the bloodstream. They are also called ductless glands.
Paracrines are known for producing hormones that act on his immediate location or producing gland
Answer:
b. newly formed viruses are released
Explanation:
This is because the end product of the lytic cycle is newly formed viruses. To summarize the cycle, the phage infects the bacterial cell, using it as a host to produce more of its kind, it infects the bacteria because it can't reproduce on its own. These newly created phages seek out new host cells to infect.
Answer:
DNA is considered to essential be the “instructions” or “blueprints” of life because it contains the code for the proteins that give you your traits.
Answer:
4. c. Deletion/ frameshift mutation
5. a. Tyr Tyr Asp Ser Gly
6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.
Explanation:
4)
A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.
5)
The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly
6)
The wild type DNA sequence is:
5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'
The mutant i.e. mRNA with the added G will be
5'
ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'
This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.
