I am found in the nucleus and I hold genes Double helix UUCGAU Nucleotides I am the type of bonds between bases on two strands of DNA Chromosomes I am the third part of a nucleotide after the base and phosphate Exported I am the number of chromosomes that are found in human body cells Ribosomes I am the site of transcription Peptide bonds I am the structures that ribosomes can be attached to if not occurring freely in the cytoplasm Nucleus I am the structure that packages and secretes proteins 46 I am the number of different amino acids that there are Deoxyribose sugar I am the number of chromosomes that are found in gametes Transcription I am the bond that links nucleotides together in a long chain Golgi apparatus I am the name given to the sugar found in RNA Endoplasmic reticulum I am what happens to proteins made in ribosomes attached to endoplasmic reticulum Codon I am the strong bonds that form between amino acids as the growing polypeptide chain is being formed Weak hydrogen bonds I am the type of RNA that brings the corresponding anti-codon and amino acid to mRNA 23 I am the base that always pairs with cytosine Strong chemical bond I am the repeating units that make up a molecule of DNA Guanine I am the number of strands in a DNA molecule I am the base that replaces thymine in an RNA strand Transfer RNA (tRNA) 2 I am the structures that mRNA are attached to during translation Ribose I am the arrangement of two strands of DNA in a twisted coil 20 I am the name given to the triplet of bases I am the structure that controls the on an mRNA strand synthesis of RNA and other components needed to build ribosomes Nucleolus Uracil I am the RNA strand that can be transcribed from the DNA sequence AAGCTA I am the process by which a mRNA strand is made from a DNA strand
