The primary photosynthetic pigment found in all algae is: MCQ with Answer and Explanation

Explanation:
DNA (deoxyribonucleic acid) is characterized by the presence of the pentose sugar deoxyribose in its nucleotide backbone. RNA (ribonucleic acid) contains the pentose sugar ribose. DNA is typically a double-stranded helical molecule, providing stability for long-term genetic storage. RNA is generally single-stranded, allowing it to fold into complex shapes and perform various functional roles like mRNA, tRNA, and rRNA. Thus, statements 1 and 2 are correct.

Explanation:
Klinefelter syndrome (47,XXY) is a sex chromosome aneuploidy causing male hypogonadism, tall stature, gynecomastia, and infertility. Turner syndrome (45,X) affects females. Down syndrome is trisomy 21. Cri du chat is deletion in chromosome 5. Nondisjunction during meiosis leads to these aneuploidies.

Explanation:
Proteomics involves large-scale study of proteins, their structures, and functions. Genomics is DNA, transcriptomics RNA, metabolomics metabolites.
