In a nucleosome, the DNA is wrapped around ribosomes a thymine dimer polymerase molecules histones

What is the function of DNA ligase? put DNA together are involved in transcription break down DNA fix the mismatch pairing are part of the ribosomes synthesis

Q: match the letters and numbers:- Replication Separation both No one   The synthesis of the chain goes from the 5 'to the 3' end 2 new chains (threads) are synthesized The process is not associated with the phases of the cell cycle The product is not complementary to the matrix (I did not get what the question meant by ' separation'. It looks like it was translated from another language to English. Or does it refer to the separation of the double helix?)

Histones are: Group of answer choices Are present in eukaryotic, but not prokaryotic chromosomes All of these are true Have tails that can be modified and thereby change how actively a gene is transcribed Generally positively charged Are the protein components of nucleosomes

An enzyme is needed for the Krebs Cycle.  It will be made following the directions contained in a gene of one of the __29__ found in the __30__ of the cell.  A portion of the double strand of __31__ splits apart between the weak__32__bonds holding the bases together.  This portion contains the code for building the enzyme.  The code message begins with a triplet call a _33__ , followed by the code, then signals the end with a triplet called the _34__.  The DNA is composed of groups of three molecules called __35__ . They are made up of ribose __36__, a __37___ for additional support, and a nitrogenous __38___.  These match up with complementary ones on the opposite strand of DNA.   A cytosine will pair up with __39___.  An RNA uracil will pair up with __40___ on the DNA.  When they line up and join, a __41__ RNA strand is formed.   This process of copying the code into RNA is called __42__.  The RNA will move out to the cytoplasm, to an organelle called a __43__.  There, __44___ RNA…

can someone help with this
