1) 3 days ago, a pt recieved her 3rd immunization with TT ..what class of antibodies specific for TT would one find in her serum?
ans - low concetration of IgM , high conc of IgG
2) which of the factors most influence the lingual concavity of max anterior teeth and groove direction of posterior teeth?
ans- Bennett movement
3)If anticodon on t -RNA is 5'ACG3' thn its corresponding codon on m-RNA is?
ans - 5'CGU3'
CAN ANYONE EXPLAIN ME HOW THESE ANS ARE RIGHT...
I m not sure with 1 but you are correct with 2 and 3.
2) As far as I understand (I actually studied this about 5 hrs ago
), you know how posterior teeth have a cusp hitting central fossa...etc? When you are moving it laterally (working; bennett movement), it will move from central fossa to groove(facial groove). For example, distobuccal cusp of mand 1st molar that was hitting the central fossa of max 1st molar is gonna pass the facial groove of max 1st molar, right (m i right?) so it's true that groove direction would be affected by Bennett movement when it comes to posterior.
When it comes to anterior teeth, I am not positive whether i understood this correctly or not but I think mandibular cusps are scretching(i don't know if this is right term LOL
) the lingual concavity of max teeth.
3) A = T (in DNA replication) or U (when paired into RNA)
G = C (in both DNA and RNA)
5 = 3
FYI, A and T are connected via 2 H bond whereas G and C are connected via 3 H bond so more contents of GC provide more stability and higher melting point.
Now, if you are interested in learning more about Bennett movement, maybe you can answer my question above as well
edit: I thnk I might be able to answer 1st one
our body got more IgG then any other antibodies followed by IgA.
IgM shows up 1st when you encounter a specific antigen for the very first time.
But if you encounter it for the 2nd time, IgG will show up even faster than IgM.
Since the question said he encountered it for the 3rd time, I think that's what this question was asking and IgG is the correct answer.
