In eukaryotic cells, the process indicated by arrow A occurs in the — cytoplasm ribosome nucleus cell membrane [Default] [MC Any] [MC All]
Answer A In the diagram DNA is changing to mRNA and this can only occur in the nucleus because DNA can not leave the nucleus
RNA and DNA are which type of organic compound? carbohydrate lipid protein nucleic acid [Default] [MC Any] [MC All]
Answer D The NA stands for Nucleic Acid
Only found in the Nucleus, can not leave DNA RNA Both [Default] [MC Any] [MC All]
Answer A DNA is not allowed to leave the nucleus, it’s too big to fit through the nuclear pours. RNA’s job is to leave the nucleus.

The type of molecule represented at A is synthesized according to a template found in Dipeptides amino acids DNA RNA [Default] [MC Any] [MC All]
Answer C The question is asking what template is used to make mRNA….. DNA is used to make mRNA mRNA Amino Acids tRNA
5' ATCAGCGCTGGC 3' The above sequence of DNA is part of a gene 5' ATCAGCGCTGGC 3' The above sequence of DNA is part of a gene. How many amino acids are coded for by this segment? 4 8 12 20 [Default] [MC Any] [MC All]
Answer A Break it up into groups of 3 ATC- AGC- GCT- GGC So there are 4 groups of 3 so it will code for 4 amino acids
A section of DNA that codes for a protein is a(n) _____. Chromosome Codon Anti-codon Gene [Default] [MC Any] [MC All]
Answer D Definition of a Gene- segment of DNA that codes for a protein
Which cellular function does this model represent? Replication Transcription Translation Mutation [Default] [MC Any] [MC All]
Answer C The picture tells you this is a Ribosome and that there is tRNA and there are amino acids. This process is Translation
What is the structure of DNA single helix double helix triple helix circular [Default] [MC Any] [MC All]
Answer B
Structure B represents a molecule of transfer RNA cytoplasmic DNA ribosomal RNA nuclear DNA [Default] [MC Any] [MC All]
Answer A Structure B is in a group of 3 and is carrying structure E which is bonded to D and C (amino acids) so it must be a tRNA. tRNA carry amino acids and match up to mRNA.

Answer C ACAGTGC UGUCACG
Which of the following have 3 types? DNA RNA Both [Default] [MC Any] [MC All]
ANSWER B RNA has 3 types- mRNA, tRNA & rRNA
Given a DNA strand of GCAGCGAGC What are the amino acids Arg- Ala- Ser Ser-Arg-Stop Arg-Arg-Ser Thr-Arg-Ser [Default] [MC Any] [MC All]
Answer C When given DNA as GCA GCG AGC CGU CGC UCG Arg-Arg-Ser
Has the Nitrogen base U DNA RNA Both [Default] [MC Any] [MC All]
ANSWER B Roses are red Violets are blue DNA has T RNA has U
Takes place in the nucleus of the cell replication transcription Translation Both A and B [Default] [MC Any] [MC All]
Answer D Both replication and transcription take place in the nucleus because you are using DNA and DNA is not allowed out of the nucleus
In a eukaryotic cell, which of the following processes directly involves DNA? translation cellular respiration active transport of ions replication of chromosomes [Default] [MC Any] [MC All]
Answer D That’s the only answer that uses DNA Translation is in the ribosome with mRNA & tRNA Cellular Respiration is making ATP in the mitochondria Active transport is how you get things into the cell when going low to high concentration
A set of 3 nucleotides of mRNA is Gene Chromosome Codon Anti-codon [Default] [MC Any] [MC All]
Answer C Def of codon is a set of 3 nucleotides found on mRNA or DNA
In eukaryotic cells, the process indicated by arrow B occurs in the — cytoplasm ribosome nucleus cell membrane [Default] [MC Any] [MC All]
Answer B In process b you are taking mRNA and turning it into a protein and ribosomes is where proteins are made
One similarity between DNA and messenger RNA molecules is that they both contain the same sugar genetic codes based on sequences of bases a nitrogenous base known as uracil double-stranded polymers [Default] [MC Any] [MC All]
Answer B DNA has sugar Deoxyribose and RNA has Ribose DNA has T and RNA has U DNA is double stranded and RNA is single stranded
Goes through the process of Transcription DNA RNA Both [Default] [MC Any] [MC All]
Answer C During transcription you copy DNA into RNA
