biology

• The nucleus is the control center of the cell, containing the genetic material.
• what does does is permanent storage place for STORAGE?

  GENETIC INFORMATION
• is DNA double helix?

  YES
• what does dna runs?

  ANTIPARALLEL
• This strand holds the information that codes for various genes

  TEMPLATE STRAND
• the other complementary strand is called?

  CODING STRAND.
• ADENINE IS PAIRS WITH WHAT? AND GUANINE?

  THYMINE AND CYTOSINE
• what do you call the bases that are held together?

  HYDROGEN BONDS
• WHAT IS THE PURPOSE OF RNA

  responsible for moving genetic information from dna in the nucleus
• similar to DNA what made of rna is?

  NUCLEOTIDE SUB UNITS
• SINGLE UNCOILED STRAND

  mRNA
• IT CARRIES THE GENETIC INFORMATION FROM DNA IN NUCLEUS TO CYTOSOL OF CELL

  mRNA
• It has 80 nucleotides


  tRNA
• it shapes like hairpin shape that binds to specific amino acids helps from polypetide chains

  tRNA
• Is joined by proteins makes up ribosomes


  rRNA
• It is the most abundant type of RNA

  rRNA
• TRUE OF FALSE is DNA NUCLEOTIDE THE MONOMER OF DNA?

  TRUE
• WHAT IS THE PENTOSE SUGAR OF DNA

  DEOXYRIBOSE
• Ribonucleic is the monomer of the rna that has

  RIBOSE AS ITS SUGAR RESIDUE
• what are the nitrogenous bases of DNA

  ADENINE,GUANINE,CYTOSINE,THYMINE
• the nitrogenous base of RNA

  ADENINE GUANINE CYTOSINE URACIL
• WHAT IS THE FUNCTION OF DNA NUCLEOTIDE?

  It stores genetic information and cellular information
• WHAT IS THE FUNTION OF RNA NUCLEOTIDE

  COPIES DNA CODE TRANSPORTS AMINO ACID AND USED FOR PROTEIN SYNTHESIS
• it is made of 20% of human body

  PROTEINS
• does the funtion of protein depends on the structure?

  yes
• • does every codon has specific amino acids 


  yes
• how many codons are there

  64
• what are the stop codons

  UAA UAG UGA
• what are the steps of DNA REPLICATIO

  INITIATION,ELONGATION TERMINATION
• dna helicase opens the dna helix by breaking h bonds between the


  NITROGENOUS BASES
• what structured form from this process?

  REPLICATION FORK
• It initiates the start of the

  elongation
• what is the purpose of SINGLE STRANDED BINDING

  It protects it from breakage to prevent it from renaturing
• it initiates the start of the elongation process


  initiation
