Here's the completed crossword puzzle for Nucleic Acids, with all answers filled in and explained.
---
1. NUCLEOTIDES
*The building blocks of nucleic acids.*
→ Nucleotides are composed of a sugar, phosphate group, and nitrogenous base. They link together to form DNA and RNA strands.
3. ADENINE
*In DNA Thymine will always bond with...*
→ In DNA, thymine (T) pairs with adenine (A) via two hydrogen bonds. This is part of complementary base pairing.
8. CODON
*The corresponding three-base sequence on the mRNA*
→ A codon is a sequence of three nucleotides on mRNA that specifies a particular amino acid during protein synthesis.
10. HYDROGEN
*Weak ....bonds join complimentary nitrogenous bases*
→ Hydrogen bonds hold complementary base pairs together (A-T and G-C in DNA; A-U and G-C in RNA). These are relatively weak, allowing DNA to unzip during replication.
11. GENOME
*The human ....... is the complete set of DNA, including all of the genes*
→ The genome refers to the entire set of genetic material (DNA) in an organism — in humans, this includes ~20,000–25,000 genes.
12. URACIL
*RNA contains ..... instead of thymine*
→ RNA uses uracil (U) in place of thymine (T). So in RNA, adenine pairs with uracil.
13. GUANINE
*Purines consist of adenine and ....*
→ Purines are double-ring nitrogenous bases: adenine (A) and guanine (G).
14. SEQUENCES
*DNA ...... are used to determine how closely related different species are to each other*
→ Comparing DNA sequences (especially conserved regions) helps scientists understand evolutionary relationships between species.
15. CYTOSINE
*Pyrimidines consist of Thymine and ....*
→ Pyrimidines are single-ring nitrogenous bases: cytosine (C), thymine (T) in DNA, and uracil (U) in RNA.
---
2. RIBOSOMAL
*This type of RNA forms the ribosomes and produces proteins*
→ Ribosomal RNA (rRNA) is a key structural and functional component of ribosomes, where protein synthesis occurs.
4. INTRON
*This type of DNA separates genes to minimize the effects of mutations*
→ Introns are non-coding sections of DNA that interrupt coding sequences (exons). They can buffer against mutations and allow for alternative splicing.
5. NUCLEUS
*RNA is located mainly in the ..... and cytoplasm*
→ In eukaryotic cells, RNA is transcribed in the nucleus and then transported to the cytoplasm for translation.
6. MITOCHONDRIAL
*DNA found specifically in the mitochondria*
→ Mitochondrial DNA (mtDNA) is a small circular genome found in mitochondria, inherited maternally.
7. GENES
*Hereditary information is encrypted in sections of DNA called....*
→ Genes are segments of DNA that code for proteins or functional RNA molecules — they carry hereditary instructions.
9. DEOXYRIBOSE
*A sugar present in DNA*
→ Deoxyribose is the 5-carbon sugar in DNA nucleotides. RNA uses ribose, which has an extra oxygen atom.
