science DNA

Question 1

carry the genetic blueprint of the cell and instructions for the functioning cell. stores all genetic information. process genetic information. synthesize protein

Answer 1

Nucleoid Acids

Question 2

DIFFERENCE BETWEEN DNA AND RNA

Answer 2

Dna is double stranded and produces double helix. Its deoxyribose and uses the bases A,T, C, AND G while RNA is single stranded and is ribose. It uses the bases A, U, C , G

Question 3

what does DNA do

Answer 3

carries genetic information and transfers genetic material. codes for genes

Question 4

structure of a double helix model

Answer 4

anti-parallel. DNA is made up of the phosphate group. made out of 5’ carbon sugar called deoxyribose. has nitrogen gases.

Question 5

bases are linked by

Answer 5

hydrogen bonds

Question 6

What are the steps in Replication

Answer 6

1. unwinding and unzipping. helicase is the zipper and the upper strand is the leading strand and lower is the lagging strand.
2. complementary base pairing
3. joining where DNA ligase is like glue and glues all the molecules back together

Question 7

genetic information encded in DNA is transferred to an RNA molecule

Answer 7

transcription

Question 8

genetic code contained with mRNA molecule is docded to produce the specific sequence of amino acids

Answer 8

translation

Question 9

STEPS IN TRANSCRIPTION

Answer 9

1. Polymerase binds
2. RNA polymerase unwinds double helix strand
3. RNA polymerase moves around one strand of the DNA
4. complementary base pairing proceeds
   5.mrNA is processed and goes to the nuclear pore

Question 10

STEPS TO TRANSLATION

Answer 10

1. mRNA attached to small ribosomal unit of RNA called rRna
2. rRna reads 3 mRna sequence bases
3. tRNA binds with mRna with codons
4. amino acids are lined up according to dictated by data
5. elongation until STOP
6. stop signal stops, tRNA will releaze the completed polypeptide chain
