When Dna Is Replicated, How Many Of The Strands Are Old? ______ How Many Are New? ______

When DNA is replicated, how many of the strands are old? ______ How many are new? ______

 

DNA Replication occurs through semi-conservative model.

According to this model, strands of a DNA uncoils during replication. Each half strands synthesizes new one to form two DNA.

Hence, half of the strands of total replicated DNA will be old and other half new.

When one DNA replicates:

▪ Two strands are new

▪Two strands are old.

Use The Periodic Table To Identify The Number Of Core Electrons And The Number Of Valence Electrons In Each Case Below., Potassium (K): 1s22s22p63s23p

Use the periodic table to identify the number of core electrons and the number of valence electrons in each case below. Potassium (K): 1s22s22p63s23p64s1 core electrons valence electrons   Potassium (K) has : core electrons : 18 valence electron : 1 Further explanation Valence electrons are electrons used in forming bonds and are in the outer shell of an element.   The main group elements usually use electrons in the subshell ns and np   While the transition elements in the subshell (n-1) d   The location of the elemental groups in the periodic system is determined by the number of valence electrons in the last sub-shell   The period of an element is determined from the valence shell (the biggest main quantum number (n))         Core electrons are electrons that belong to atoms except for valence electrons. It is located close to the core and fills the inner shell.   Electron configurations from K :Ar 4s¹ or 1s²2s²2p⁶3s²3p⁶ 4s¹ From this electron configuration , number ...
