Sir William Henry Bragg
Frage 11
Frage
What rules were created by Erwin Chargaff in the 1940's?
Antworten
-
-nucleotides are not arranged in the same order in all species -in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine. -the amount of adenine plus guanine is always equal to the amount of thymine plus cytosine
-
-nucleotides are not arranged in the same order in all species -in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine. -each genetic code contains 'instructions' for a specific protein
-
-each person has 46 chromosomes, in 23 pairs -in all species, the amounts of adenine and thymine in the DNA are always similar, as are the amounts of guanine and cytosine. -the amount of adenine plus guanine is always equal to the amount of thymine plus cytosine
-
-the amount of adenine plus guanine is always equal to the amount of thymine plus cytosine -DNA determines characteristics -each genetic code contains 'instructions' for a specific protein

Antworten
-
1968
-
1869
-
1986
-
1896
Frage 17
Frage
What is the term used to describe the copying of DNA?
Antworten
-
copying
-
doubling
-
replication
-
imprinting
Frage 18
Frage
What happens in the process of replication?
Antworten
-
1. the strands of the double helix separate from each other, much like a zip unzipping, leaving the bases exposed
-
2. the exposed nucleotides pair with the exposed bases
-
3. the sugar and phosphate molecules bond with neighbouring nucleotides, creating two identical DNA strands
-
1. the DNA strand is split in half horizontally
-
2. it is then separated in half, much like a zip unzipping, exposing the bases
-
3. the bases then replicate and attach to the exposed bases
-
4. the DNA strands then 'rezip', creating two identical DNA strands
