In eukaryotic cells, the process indicated by arrow A occurs in the — A. B. C. D. cytoplasm ribosome nucleus cell membrane

Answer • A • In the diagram DNA is changing to m. RNA and this can only occur in the nucleus because DNA can not leave the nucleus

RNA and DNA are which type of organic compound? A. B. C. D. carbohydrate lipid protein nucleic acid

Answer • D • The NA stands for Nucleic Acid

Only found in the Nucleus, can not leave A. DNA B. RNA C. Both

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.

Answer • B • When given DNA as: TCA GCA ATC AGU CGU UAG Ser- Arg- Stop

The type of molecule represented at A is synthesized according to a template found in A. B. C. D. Dipeptides amino acids DNA RNA

Amino Acids • C • The question is asking what template is used to make m. RNA…. . DNA is used to make m. RNA Answer t. RNA

5' ATCAGCGCTGGC 3' The above sequence of DNA is part of a gene. How many amino acids are coded for by this segment? A. B. C. D. 4 8 12 20

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) _____. A. B. C. D. Chromosome Codon Anti-codon Gene

Answer • Definition of a Gene- segment of DNA that codes for a protein

Which cellular function does this model represent? A. B. C. D. Replication Transcription Translation Mutation

Answer • C • The picture tells you this is a Ribosome and that there is t. RNA and there amino acids. This process is Translation

What is the structure of DNA A. B. C. D. single helix double helix triple helix circular

Answer • B

Structure B represents a molecule of A. B. C. D. transfer RNA cytoplasmic DNA ribosomal RNA nuclear DNA

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 t. RNA carry amino acids and match up to m. RNA.

A base sequence is shown below. ACAGTGC How would the base sequence be coded on m. RNA? A. B. C. D. TGTCACG GUGACAU UGUCACG CACUGUA

Answer • C ACAGTGC UGUCACG

Which of the following have 3 types? A. DNA B. RNA C. Both

ANSWER • B • RNA has 3 types- m. RNA, t. RNA & r. RNA

Given a DNA strand of GCAGCGAGC What are the amino acids A. B. C. D. Arg- Ala- Ser-Arg-Stop Arg-Ser Thr-Arg-Ser

Answer • • • C When given DNA as GCA GCG AGC CGU CGC UCG Arg-Ser

Has the Nitrogen base U A. DNA B. RNA C. Both

ANSWER • B Roses are red Violets are blue DNA has T RNA has U

Takes place in the nucleus of the cell A. B. C. D. replication transcription Translation Both A and B

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? A. B. C. D. translation cellular respiration active transport of ions replication of chromosomes

Answer • D • That’s the only answer that uses DNA – Translation is in the ribosome with m. RNA & t. RNA – 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 m. RNA is A. B. C. D. Gene Chromosome Codon Anti-codon

Answer • C • Def of codon is a set of 3 nucleotides found on m. RNA or DNA

In eukaryotic cells, the process indicated by arrow B occurs in the — A. B. C. D. cytoplasm ribosome nucleus cell membrane

Answer • B • In process b you are taking m. RNA 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 A. B. C. D. the same sugar genetic codes based on sequences of bases a nitrogenous base known as uracil double-stranded polymers

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 A. DNA B. RNA C. Both

Answer • C • During transcription you copy DNA into RNA

What amino acids would this codon AUGGGGAAA code for? A. B. C. D. Tyr-Pro-Phe Tyr-Gly-Lys Met-Arg-Ser

Answer • C • codon AUG-GGG-AAA • This has already been transcribed into m. RNA so just look it up

Molecules C, D, and E will combine to form part of A. B. C. D. RNA a polysaccharide DNA a polypeptide

Answer • D • Those 3 things are amino acids and they will form polypeptide bonds to make a protein

In eukaryotic cells, the process indicated by arrow A is called— A. B. C. D. Replication Transcription Translation Photosynthesis

Answer • B • Transcription is the process where DNA is copied into m. RNA

A goes with T A. replication B. transcription C. translation

Answer • A • Transcription and translation make & use RNA has A with U NOT T
