Answer:
The correct answer is d Lysosomes contain enzymes to breakdown damaged cellular material.
Explanation:
Lysosomes are called digestive organelle that contain many hydrolytic enzymes such as acid hydrolase ,peptidase, nuclease etc which aids in the digestion of various cellular components such as carbohydrates,protein,nucleic acid.
Lysosome perform the same function by the formation of auto phagolysosome which contain the those cellular molecules and organelles those are targeted for degradation.
Answer:
The answer would be,, <em>Cohesion</em> and <em>Surface Tension.</em>
Explanation:
Ans.1. False.
RNA or ribonucleic molecules are polymer of nucleotide molecules that perform various functions in a cell. rRNA is referred as ribosomal RNA and are involved in synthesis of ribosomes along with proteins. Ribosomes are described as molecular factory for protein synthesis, hence, rRNA plays an important role in protein synthesis.
Thus, given statement is false.
Ans.2.
Transcription is defined as a process, by which a parental DNA molecule gets transcribed into a RNA molecule with the help of RNA polymerase enzyme. The RNA molecule is then, translated into a specific polypeptide chain or protein.
According to central dogma of molecular biology, genetic information flows from a DNA molecule to a protein. During this, first step includes transcription (formation of RNA from DNA) and second step includes translation (formation of protein form RNA).
Thus, transcription plays an important role in the central dogma of molecular biology.
