Answer:
DNA is stored in the nucleus, the mRNA goes to the nucleus, making a copy of that DNA, since the actual DNA cannot come out.
Explanation:
Uniform cells are produced when cells differentiate.
Answer:
(E) left atrium.
Explanation:
Pulmonary veins are veins that carry oxygenated blood from the lungs to the heart (left atrium). These veins are part of the pulmonary circuit:
Venae cavae are a vessels (vena cava interior and superior) that carry deoxygenated blood from the body to the right atrium. From the right atrium through the tricuspid valve the blood goes into the right ventricle. Then, from the right ventricle through the pulmonary valve the blood goes into the main pulmonary artery which carries deoxygenated blood to the lungs (to recieve oxygen). Oxygenated blood from the lungs travels to the heart: two pulmonary veins from each lung to the left atrium.
The connecting piece of a sperm is packed with gonads that produce energy.
Sperm is the male reproductive cell and is derived from the Greek word "Sperma" Significance is Root.
Sperm cannot divide and have limited life span, but after fusion with egg cells through fertilization, a substitute orgasm begins developing, starting as a totipotent zygote
Answer:
C) Non-protein-coding DNA that is transcribed into several kinds of small RNAs with biological function.
Explanation:
The genome of humans consists of a variety of protein-coding and non-protein coding sequences. The protein-coding sequences are the sequences which can get translated into the protein sequences.
When the genome was sequenced, it was expected that the size of these coding sequences will be larger but the sequences came to be smaller. This shows that the rest of the genome is made of the non-coding sequences.
The importance of these non-coding sequences is that they do not form the proteins but they can undergo transcription and form the variety of RNA molecules like the regulatory RNA, the ribosomal RNA and others.
Thus, Option-C is the correct answer.
