A section of DNA is determined to have 24% thymine. The same section of DNA must have this percentage of guanine.
What is 26%?
100
This is the sequence of the template strand of DNA if the nontemplate strand has the sequence 5' CCGTAACG 3'
What is 3' GGCATTGC 5'?
100
This part of mRNA leaves the nucleus for translation.
What is the exon?
100
These are the two main types of mutagens.
What are chemicals and radiation?
100
These are the four bases involved with DNA. Label purines and pyrimidines.
What are adenine, guanine, cytosine, and thymine? purines - adenine, guanine pyrimidines - cytosine, thymine
200
True/False: Griffith was the first scientist to determine the DNA was the genetic material in a cell.
What is false?
200
List the four enzymes used in DNA replication and their functions.
What are DNA helicase, DNA ligase, RNA primase, and DNA polymerase? DNA helicase - unwinds and unzips DNA DNA ligase - connects Okazaki fragments RNA primase - adds a short segment of RNA to start replication DNA polymerase - adds nucleotides to new DNA strand
200
These are the places where each step of the central dogma take place (in eukaryotic cells).
What are transcription - nucleus translation - cytoplasm protein synthesis - cytoplasm
200
This will happen to the production of tryptophan in the cell when tryptophan is present.
What is a decrease?
200
This is the type of mutation when a DNA segment is changed from 5' ACCTGTCAA 3' to 5' ACCTTGTCAA 3'.
What is insertion/frameshift mutation?
300
Draw a DNA model including the shape and the orientation of the strands.
See drawing on the board. :)
300
If you see DNA replicate with only one point of origin, it must be this type of cell.
What is prokaryotic?
300
This is the amino acid sequence for the DNA code 5' TCCAGC 3'.
What is alanine, glycine?
300
This will happen to the production of enzymes for lactose digestion when lactose is present in the cell.
What is increase?
300
These are the places where each step of the central dogma take place (in prokaryotic cells).
What is transcription - cytoplasm translation - cytoplasm protein synthesis - cytoplasm
400
These are the parts of a nucleotide.
What are 5-carbon sugar, phosphate group, and nitrogenous base?
400
You will find these only on the lagging strand.
What are Okazaki fragments (or DNA ligase)?
400
Draw and label the 3 parts of activated tRNA.
See picture.
400
A mutation in this part of the mRNA will have the least impact on the cell.
What is the intron?
400
This is the reason DNA is said to be antiparallel.
What is one strand is in the 5' to 3' direction and the complementary strand is 3' to 5'?
500
This is how DNA (which is several centimeters long) fits inside a cell's nucleus.
What is DNA wraps around histone proteins to form a nucleosome?
500
During this process, parental strands of DNA separate, serve as templates, and produce DNA that has one strand of parental DNA and one strand of new DNA.
What is semiconservative replication?
500
This nitrogenous based is used during RNA synthesis instead of this nitrogenous base used during DNA synthesis.
What is uracil instead of thymine?
500
Given the DNA sequence 5' AGG 3', the mRNA sequence would be 5' CCU 3'. A mutation in this position of the mRNA codon would have the least impact on the function of the cell.
What is the third position? (U)
500
Here is an mRNA sequence 5' UUUGCUAAGUAUG 3' found in the nucleus. After processing, the mRNA sequence is 5' UUUGCUAUGAAAAAAAAA 3'. This what happened.
What is the intron was removed and a poly-A tail was added?
