The process that converts mRNA code into a sequence of amino acids is:
A. Translocation
B. Translation
C. Transcription
D. Replication
Answer: Option B
Solution (By JKExamLibrary)
Translation occurs at ribosomes, where tRNA anticodons recognize mRNA codons and add the corresponding amino acids to a growing polypeptide chain. Replication duplicates DNA, transcription synthesizes mRNA from DNA, translocation is movement of chromosomes or protein transport.
Explanation:
Follicle-stimulating hormone (FSH) from the anterior pituitary promotes the growth and maturation of ovarian follicles and stimulates estrogen secretion. LH triggers ovulation, estrogen proliferates endometrium, progesterone maintains it.
Explanation:
Relaxin is a peptide hormone produced by the corpus luteum and the placenta during pregnancy. Its primary roles are to relax the smooth muscles of the uterus (inhibiting contractions to maintain pregnancy) and to soften and increase the flexibility of the connective tissues in the pelvis, specifically the pelvic ligaments and the pubic symphysis. This relaxation and widening of the pelvic joints facilitate the passage of the baby through the birth canal during delivery.
Explanation:
Chloroplasts are the sites of photosynthesis in plant cells, converting solar energy into chemical energy (food). Hence they are called the kitchen of the cell. Mitochondria are the powerhouse, generating ATP; ribosomes are protein factories; Golgi apparatus is the packaging center.
