my question is... if you have a DNA strand; ATT CCG CAT CCG GTT
what would be after 1. replication? 2. transcription? 3. translation?
and what anti- codons would be involved?
After replication, which DNA strand do you use to transcribe?... uggg!
PLEASE HELP!

Your strand: ATT CCG CAT CCG GTT
Replication:
ATT CCG CAT CCG GTT
TAA GGC GTA GGC CAA
Transcription: UAA GGC GUA GGC CAA
Translation: Stop (UAA codes for stop codon so, no further translation in that reading frame)
Which strand used as template (for transcription) depends upon which DNA strand (5'->3' OR 3'->5') contains the promoter, specifically the TATA box (eukaryotes) or Pribnow box (bacteria). Promoter is the actual site where RNA polymerase binds and start transcription. For example, if 3'->5' contains promoter sequence then this strand will be used as template strands(the strand used for coping) while the 5'-3' will be the coding strand(the strand with the actual product info, protein or functional RNA).
The process of transcription is quite complicated in eukaryotes because the involvement of transcription factors in addition to RNA polymerase. Read these wikipedia articles for more info.

During DNA replication, a strand of DNA is used to make a 2nd DNA strand, that is a copy of the first. During transcription, an RNA copy is made from a portion of a DNA strand. The RNA is an intermediate step between DNA and protein. During translation, the information on a messenger RNA molecule is used to make a chain of amino acids, a protein.
Replication is the process in which a cell makes an exact copy of its own DNA (copy DNA -> DNA). Replication occurs in the S-fase in preparation to cell division during which the genetic information for the synthesis of proteins is transfered from the mothercell to the daughtercell. Whether this cell division will eventually be a mitosis or a meiosis (more on differences), in either case during replication the entire DNA is copied in which the genetical code is encrypted as a sequence of nitrogenous bases.
The protein synthesis occurs by means of transcrition (in the nucleus: production of RNA with nitrogenous bases that are complementary to one of the DNA strands; thus DNA -> RNA) and translation (in polyribosomes and the rough endoplasmatic reticulum both located in the cytoplasm: RNA codes -> specific chains of aminoacids, i.e. polypeptide, the precursors of proteins). Proteins are involved in all vital functions in cells, including enzymatic catalyzation, transport, storage, movement, support, signaling,defence and control.
