Question
An eryme to break down oxygon radicals is found in the C catabolites microsomes bacteria 23. The are called mature cells of plants contain large fhuid-Gilled sacs, occupying most of the volume of the cell, these large andhelp tho cell's maclcoli. mtocindria, esmotic pressure protein symthesis plasma membrane, secretion central vacuoles, turgor pressure A particular cell steadily secretes a protein into the surmounding medium. The secrction is released from the depot for glysogen. The cell can be identified as ecoeytosis from membranous vesicles derived from the Golgi complex. The cell also functions as a storage bacterium Beyanoha terium 25. During the developasent Ccell from terrestrial plantpicell from an animal of a frog from a tadpole, enzymes that destroy cells crode away from the tail. These enzymes must be liberated from the A, chromosomes @endoplasmic reticulum 26. The five carbon sugar found in RNA is ¢lysosomes pmacleuspevacanies dextrose deoxyribose dnbose peglucoseribulose consists of DNA 28. DNA and RNA are different types of nucleic acid polymer. Which of the following is true of RN.A but NOT true of DNA? It contains uracil. t contains thymine it is single stranded Two of these are correct for RNA but not DNA. pr It has 5-to-3 29. Two nucleotides are linked together using 30. The two molecules that alternate to form the backbone of a polynucleotide chain are bonds. diether/rphospholipid Rpeptide ophosphodiester panic Beytosine and guanine, C sugar and phosphate. adenine and thymine. Z base and phosphate. base and sugar direction(s) and must be if they are to bond Two chains of DNA must run in 31. with each other opposite, uncomplimentary parallel; uncomplementary D antiparallel; complementary the same; uncomplimestary parallel: complementary 32 If approximately 20 percent of the nucleotides in human DNA contain thymine, what percentage of the nucleatides contain guanine? A.20% B.30% C40% D.50% E60% 33. Which of the followigg most likely represents part of a strand of RNA rathes than DNIA? AAGGTO types ofisonens. 34. These are identified asExplanation / Answer
22) Peroxysomes
23) central vaculole and turgor pressure
24) cell from an animal
25) endoplasmic reticulum
26) Ribose
27) protein
28) two of these are correct for Rna but not for DNA ie RNA contains uracil and is single stranded.
29) Phosphodiester bonds
30) sugar and phosphate
31) Antiparellel and complimentary
32)30%
A=T,G=C
A+T+G+C=100%
T=20
A=20
20+20=100
100-40= 60% of G and C
G+C=60% and G=30%
33) ACUUAG as RNA contains Uracil
34) functional type of isomers as CH3CH2OH ( ETHANOL) is isomerised to CH3 -O-CH3 (DIMETHYL ETHER)
